Abstract
Description
Background Technology
[0001] This invention relates to the selection, preparation, and extraction of pistachio seed kernels to obtain standardized levels of melatonin from natural sources.
[0002] Melatonin has been widely used as a dietary supplement ingredient, primarily for supporting and regulating healthy sleep patterns, overcoming jet lag, and improving mild sleep disorders.
[0003] Melatonin was once commercially produced from the pineal glands of cattle and pigs, making it animal-derived. As concerns about animal-derived sources have grown, particularly with the emergence of viruses such as mad cow disease and foot-and-mouth disease, people have begun seeking alternative sources of melatonin. Most commercially available melatonin dietary supplements utilize synthetically produced melatonin.
[0004] As more people shift towards sustainable, plant-based diets, the demand for plant-based ingredients such as melatonin is growing. It has also been learned that the quality of synthetic melatonin varies significantly, both in the ingredient itself and in dietary supplements / food products containing it.
[0005] Sleep is a finely regulated process driven by complex neurochemical interactions within the brain's sleep-promoting and wakefulness centers. Melatonin is central to this regulation, influencing various bodily systems and physiological processes, triggering immediate physiological responses such as fatigue, and contributing to long-term health outcomes due to its powerful antioxidant properties. Melatonin exerts this effect by activating highly sensitive receptors MT1 and MT2, which respond to changes in the light-dark cycle and directly influence circadian rhythms, sleep-wake cycles, and the synchronicity of experienced sleep duration and stages. While melatonin can activate both receptors, they have been reported to elicit different physiological responses due to their unique expression patterns, signaling pathways, and pharmacological properties in different organs. Activation of the MT1 receptor reduces neuronal activity in the suprachiasmatic nucleus (SCN), promoting sleep initiation; while activation of the MT2 receptor regulates circadian rhythm synchronicity in response to environmental cues such as the light-dark cycle. The synergistic effect of these receptors in regulating sleep duration, duration, and circadian rhythms highlights their value as potential pharmacological targets for optimizing sleep management and quality.
[0006] Clinical studies have extensively explored the routes of melatonin administration, primarily focusing on oral and intravenous administration in healthy volunteers. However, results regarding its pharmacokinetic properties are inconsistent.
[0007] Studies have revealed that oral melatonin follows first-order kinetics, with an average bioavailability of approximately 15%, but significant individual variability exists. Multiple factors, including age, caffeine intake, smoking, oral contraceptive use, food intake, and concurrent drug intake (such as fluvoxamine), can affect its pharmacokinetics. Nevertheless, melatonin appears to maintain a constant half-life of approximately 45 minutes, and peak melatonin concentrations in the bloodstream have been reported approximately 50 minutes after oral administration.
[0008] This invention attempts to solve these problems, as well as others. Summary of the Invention

[0023] Description of the implementation method Generally, methods for preparing melatonin from pistachios provide a more effective dose / serving than synthetically derived melatonin, enabling sleep regulation in an easily accessible form and consumption in dietary supplements or food products. Pistachios are a widely consumed starting material worldwide and are widely accepted as a health food. However, the fact that pistachios are a rich source of melatonin is not widely known. This method maximizes the melatonin content in the final extract by enriching the starting material, allowing an appropriate amount of melatonin composition to be consumed in the form of dietary supplements or food products to provide meaningful effects. This is the first time that a melatonin-rich product has been extracted from pistachios and presented in a form suitable for pharmaceutical and / or food delivery.
[0024] Some pistachio varieties contain high levels of melatonin, exceeding 12,000 pg / g. Furthermore, compared to other nuts, pistachios contain significantly higher levels of phytomelatonin, with some varieties reaching up to 223 µg / g. These findings highlight pistachio-derived melatonin-rich foods as a potential therapeutic option. The following examples evaluate the efficacy of naturally sourced melatonin gummies versus synthetic melatonin gummies in terms of melatonin absorption and sleep quality.
[0025] In one embodiment, the melatonin composition is bound to a complex herbal matrix comprising complementary compounds such as arginine, tryptophan, lutein, and resveratrol, and possessing high ORAC antioxidant capacity. Compared to synthetic melatonin, the melatonin composition bound to the complex herbal matrix increases the bioavailability, absorption, and efficacy of melatonin. This melatonin extract exhibits bioactivity against MT1 and MT2 receptors in terms of binding and signal transduction. The melatonin extract increases the activity of endogenous melatonin and enhances exogenous melatonin, thereby having a synergistic effect in treating sleep disorders. In one embodiment, treating sleep disorders comprises administering a small amount of the melatonin extract, in an amount of about 0.03 g to about 0.5 g, equivalent to about 300 mcg to about 5 mg of natural melatonin, to induce physiological effects in the human body.
[0026] This melatonin composition includes melatonin-rich pistachio seed / kernel extract, designed to meet the demand for plant-based melatonin that can provide a meaningful and effective dose of melatonin at a convenient dosage / serving.
[0027] like Figure 1AAs shown, a method 100 for preparing a melatonin-rich pistachio seed / kernel extract includes the following steps: Step 130, supercritical CO2 extraction to remove fatty acids and oil fractions from the seeds / kernels, thereby generating a melatonin extract; Step 140, washing the melatonin extract with water; Alternatively, Step 142, fermenting the milled seeds / kernels using yeast / culture medium; Step 150, extracting melatonin with a suitable solvent, which may include ethanol, methanol, water, acetone, hexane, butanol, and / or other suitable solvent mixtures; Step 160, repeating the extraction until process testing confirms that the melatonin determination meets the acceptance criteria; Step 170, concentrating the liquid extract solution. In one embodiment, the acceptance criterion is: not less than about 1.0% (NLT), as determined by high performance liquid chromatography (HPLC).
[0028] like Figure 1B As shown, a method 100 for preparing melatonin-rich pistachio (pistachio) seed / kernel extract includes: step 110, selecting crude pistachio (pistachio) seed / kernel raw material with an endogenous natural melatonin content between about 0.02% and about 0.04%; step 120, crushing and removing the outer shell; step 130, supercritical CO2 fluid extraction to remove fatty acids and oil fractions from the seeds / kernels; step 140, washing with water; and step 150, extraction with a suitable solvent, which may include ethanol, methanol, water, acetone, hexane, butanol, and / or others. A mixture of suitable solvents; step 160, repeating the extraction until process testing confirms that the melatonin determination meets acceptance criteria; step 170, concentrating the liquid extract solution; step 180, drying by a suitable method; step 190, standardizing until the final composition contains at least 1% melatonin; and step 200, applying quality control measures including herbal identification, melatonin potency determination, radiocarbon dating to ensure avoidance of synthetic additives, and testing for general contaminants (i.e., solvent residues, pesticide residues, aflatoxin, microorganisms, heavy metals, pyrrolizidine alkaloids, and polycyclic aromatic hydrocarbons). Standardization can be achieved by sub-batch blending or by using a suitable carrier / excipient. In one embodiment, the ratio of melatonin extract to natural extract is from about 16:1 to about 20:1, and in another embodiment, the ratio of melatonin extract to natural extract is from about 15:1. In one embodiment, the solvent is ethanol and water in a ratio of about 30:70.
[0029] A process overview for implementing this disclosure is provided in the Manufacturing Flow Chart, document number NNPVE151-MFC (valid version).
[0030] melatonin structure The chemical structure of melatonin is described by the United States National Institutes of Health National Library of Medicine - https: / / pubchem.ncbi.nlm.nih.gov / compound / Melatonin.
[0031] The chemical structure of the synthesized melatonin is identical to that found in this disclosure.
[0032] dose Melatonin compositions are available in capsule form for oral consumption. The melatonin compositions are free from any contaminants, including foreign matter, pesticides, bacterial pathogens, mold, residual solvents, and heavy metals.

[0035] In some embodiments, the dosage form is formulated as granules, pills, microparticles, tablets, or hard-shell capsules suspended in a liquid, syrup, or enema. In some embodiments, the dosage form is formulated for oral or mucosal delivery. In some embodiments, the dosage form is formulated as lozenges, candies, gummies, chocolates, or cookies. In some embodiments, the tablets or pills are immediate-release, sustained-release, or controlled-release dosage forms. In some embodiments, the tablets are enteric-coated, or melt or dissolve in the mouth, or are mucosal adhesive dosage forms.
[0036] In some embodiments, the unit dosage form is a unit particle, such as a tablet, capsule, granule, pill, microparticle, or membrane, which is enterically coated or colonically coated to protect the unit dose from degradation in the acidic gastric pH and to allow timely swelling in a pH-controlled manner or both, to release the melatonin composition in the distal intestine.
[0037] In some embodiments, the melatonin composition is formulated as a semi-solid or liquid dosage form, such as a cream, lotion, ointment, dispersant, suspension, gel, foam, spray, syrup, liquid, eye drops, ear drops, enema, or oral dosage form, or topical dosage form, or topical ophthalmic or optical, or oral, vaginal, rectal, or uterine dosage form. Liquid formulations include solutions, suspensions, and emulsions, such as water or water-propylene glycol solutions. For example, parenteral liquid formulations can be formulated as solutions in aqueous polyethylene glycol solutions. Thus, compounds according to the invention can be formulated for parenteral administration (e.g., by injection, such as bolus injection or continuous infusion) and can be present in unit doses in ampoules, pre-filled syringes, small-volume infusion sets, or in multi-dose containers with added preservatives. The composition can be in the form of a suspension, solution, or emulsion in an oily or aqueous load and may contain formulations such as suspending agents, stabilizers, and / or dispersants. Alternatively, the active ingredient may be in powder form, obtained by aseptic separation of sterile solids or lyophilization from solution, for reconstitution with a suitable carrier, such as sterile, pyrogen-free water, prior to use.
[0038] In some embodiments, any of the above compositions or any of the above dosage forms are used in methods for treating insomnia or sleep disorders.
[0039] Preferred dosage forms include, but are not limited to, any liquid, semi-solid, or solid dosage form. Melatonin compositions can be formulated into pharmaceuticals by preparing topical, mucosal, or oral delivery systems. Topical delivery systems may be in the form of eye drops, suspensions, ointments, creams, foams, sprays, or topical patches. Oral delivery systems may be tablets, capsules, soft capsules, sachets, granules, or syrups. Mucosal delivery systems may be gels, vaginal suppositories, enemas, douches, lotions, foams, mucosal adhesive gels, or tablets for immediate release or sustained or controlled release. The loading medium may include any acceptable solvent and inactive ingredients, as well as preservatives, antioxidants, and colorants. Delivery forms may be single-dose or multi-dose and may include microparticles, nanoparticles, microcapsules, liposomes, micelles, etc., known in the pharmaceutical, cosmetic, veterinary, and formulation fields. Further details on suitable dosage forms are available from any standard reference work in the field, including, for example: Remington's Pharmaceutical Sciences, Mack Publishing Co, Easton, Pa, USA (1980).
[0040] Therefore, in some embodiments of the invention, the source of the melatonin composition further includes one or more excipients selected from the group consisting of solvents, stabilizers, suspending agents, emulsifiers, release modifiers, targeting agents, and viscosity agents, and combinations thereof. In one embodiment, the excipient is about 10% to about 25% maltodextrin.
[0041] Treatment The terms “treatment” or “enhancement” are used interchangeably herein. These terms can refer to methods of achieving beneficial or desired outcomes, including but not limited to therapeutic benefits and / or preventive benefits. A therapeutic benefit can refer to the eradication or improvement of the underlying disease being treated. Furthermore, a therapeutic benefit can be achieved by eradicating or improving one or more physical symptoms associated with the underlying disease, resulting in an improvement observed in the subject, although the subject may still suffer from the underlying disease. Preventive effects include delaying, preventing, or eliminating the onset of a disease or condition, delaying or eliminating the onset of symptoms of a disease or condition, slowing, halting, or reversing the progression of a disease or condition, or any combination thereof. For preventive benefits, subjects at risk of developing a specific disease, or subjects reported to have one or more physical symptoms of a disease, may receive treatment even if they have not yet been diagnosed with that disease.
[0042] As used herein, the term "synergistic" refers to the phenomenon where the cumulative pharmacological effect of two or more components used in combination is greater than the sum of the effects tested individually. As used herein, the term "enhancing" refers to the phenomenon where the efficacy of an active ingredient is significantly enhanced when combined with a second ingredient, wherein the second ingredient itself does not show any efficacy in the same pharmacological test. In some cases of enhancing effects, the second ingredient, when measured alone, may not only fail to produce a pharmacological effect but may even cause the opposite effect. An example of this is as follows: ingredient A has an anxiolytic effect; ingredient B has an anxiolytic effect; when A and B are combined, the combined anxiolytic effect is greater than that of A alone. In the context of this invention, enhancing effects are considered a special case of synergistic effects. Therefore, the term "synergistic effect" (or synergistic, etc.) in defining the properties of the compositions of this invention also includes, within its meaning, the enhancing effects just described above.
[0043] As used herein, the term "composition" refers to a pharmaceutically acceptable composition and means compounds, materials, compositions, and / or dosage forms that, within reasonable medical judgment, are suitable for contact with the tissues of mammals (especially humans) without excessive toxicity, irritation, allergic responses, or other problematic complications commensurate with a reasonable benefit / risk ratio. Formulations include configurational isomers (such as cis and trans isomers) and all optical isomers (such as enantiomers, diastereomers), racemic isomers, diastereomers, and other mixtures of these isomers, as well as solvates, hydrates, isomers, polymorphs, tautomers, esters, salt forms, and prodrugs. The term "prodrug" refers to a compound that serves as a drug precursor, releasing the drug in vivo through some chemical or physiological process after administration (e.g., the prodrug is converted to the desired drug form upon reaching physiological pH or by enzymatic action). Exemplary prodrugs release the corresponding free acid and hydrolyzable esterifying residues of the compounds of the present invention upon cleavage.
[0044] In this disclosure, the “effective amount” or “effective dose” of a melatonin extract or composition refers to the amount of melatonin extract extracted from pistachios that, once administered to a subject, would reach the subject’s bloodstream, intestines and / or body tissues.
[0045] In one embodiment, the method includes administering or ingesting a melatonin composition as a single formulation to enhance the synergistic effect between exogenous and endogenous melatonin. The method also includes combining the melatonin composition with an herbal matrix to form a formulation to enhance the synergistic effect in treating sleep disorders or improving sleep quality.
[0046] The methods described herein may include administering an effective dose of a melatonin composition having an herbal base daily, every other day, or weekly. In embodiments, according to the invention, daily administration of a melatonin composition having an herbal base may be continued for 1-2 weeks, 1-3 weeks, 1-12 weeks, 4-8 weeks, 8-12 weeks, 1-12 weeks, 4-12 weeks, 8-12 weeks, or 12-15 weeks or longer, or other time periods.
[0047] Treatment of sleep disorders involves administering an effective amount of pistachio melatonin extract and an effective amount of herbal matrix. "Sleep disorder" is any condition that causes difficulty in falling asleep and maintaining sleep, such as insomnia, and includes conditions related to: difficulty falling asleep due to anxiety, stress, and depression; difficulty falling asleep leading to poor concentration; difficulty falling asleep due to age-related memory loss, dementia, or other cognitive impairment; difficulty falling asleep due to substance abuse, mental illness, respiratory disorders, or other sleep disorders such as periodic limb movement disorder; and difficulty falling asleep or maintaining sleep due to other sleep-related problems such as poor sleep hygiene, including alcohol consumption. Consuming caffeinated beverages, eating large meals, or engaging in physical or mentally stimulating activities shortly before bedtime; poor sleep hygiene including extremely irregular bedtimes, or unsuitable temperature, poor ventilation, noise, or light in the sleep environment; including narcolepsy and rapid eye movement (REM) sleep behavior disorders; disorders associated with neurodegenerative diseases such as Alzheimer's, Parkinson's, and multiple sclerosis; REM sleep disorders associated with drug withdrawal (especially alcohol or sedative-hypnotic drug withdrawal); and circadian rhythm disorders associated with sleep apnea, shift work, and jet lag.
[0048] Complex herbal matrix The complex herbal matrix includes complementary compounds such as arginine, tryptophan, lutein, and resveratrol, and has high ORAC antioxidant capacity.
[0049] Arginine is an amino acid with the formula (H2N)(HN)CN(H)(CH2)3CH(NH2)CO2H. L-arginine is considered safe (GRAS status) when the daily intake is up to 20 grams. L-arginine (0.15-0.60 μmol) is a nitric oxide precursor and can regulate sleep, such as increasing slow-wave sleep and reducing wakefulness.
[0050] Tryptophan is an α-amino acid used in protein biosynthesis. It comprises an α-amino group, an α-carboxyl group, and an indole side chain, making it a polar molecule with nonpolar aromatic β-carbon substituents. Tryptophan is also a precursor to the neurotransmitter serotonin, the hormone melatonin, and vitamin B3. Tryptophan contributes to good sleep because the body uses it to synthesize serotonin (a neurotransmitter). Serotonin helps regulate sleep and is used in the synthesis of melatonin (a hormone that promotes sleep).
[0051] Lutein is a xanthophyll compound and one of the 600 known naturally occurring carotenoids. It has been shown to reduce the duration of sleep deprivation, i.e., less than 7 hours of sleep per day. Lutein and zeaxanthin are isomers, differing only in the position of a single double bond. Lutein and zeaxanthin can interconvert in vivo via an intermediate called meso-zeaxanthin. 100 g of pistachios contain 1,205 mcg of lutein.
[0052] Resveratrol (3,5,4'-trihydroxy-trans-stilbene) is a stilbene, belonging to the class of natural phenols or polyphenols and phytoprotective agents. Resveratrol exists in two geometric isomers: cis (Z) and trans (E), with the trans isomer shown in the image above. Resveratrol is usually conjugated with glucose. Resveratrol is known to induce sleep and reduce active-wake time and abnormal sleep patterns. Sleep observations and electroencephalogram (EEG) measurements indicate that resveratrol significantly improves non-REM sleep, which is considered the most important aspect of normal sleep.

[0073] A cannula is inserted into the antecubital vein to collect baseline blood samples.
[0074] Participants took the assigned IP with 250 mL of water.
[0075] Blood samples were collected at 10, 20, 30, 45, 60, 75, 90, 120, and 150 minutes, as well as at 3, 4, 6, and 8 hours after ingestion.
[0076] After all samples were collected, the cannula was removed.
[0077] Meals will be provided as follows: Breakfast: after taking IP; Lunch: 4 hours after blood sample collection; and snacks: in the afternoon (all food intake will be recorded by the trial coordinator).
[0078] Drinking water is unrestricted (you can drink as much as you want).
[0079] 5. Supplementation Phase 1: Take the assigned IP at home for 7 days. 6. Cleaning period: Two weeks between replenishment stages. 7. Baseline 2: Sleep records were taken for 3 days prior to visit 3. 8. Visit 3: PK 2: The procedure is the same as Visit 2. 9. Supplementation Phase 2: Take the assigned IP at home for 7 days.
[0080] 10. Final interview: conducted by telephone.
[0081] Participant Requirements: Participants were required to complete a 3-day baseline sleep diary before both Visit 2 and Visit 3 to establish a stable sleep pattern. Daily online sleep diaries were also required during each 7-day supplementary period. Unused IPs after Visit 2 were returned at Visit 3. Unused IPs after Visit 3 were destroyed at the end of the study.
[0082] Blood Sampling and Measurement: During the PK visit, blood samples were collected over 8 hours using the method described above. After the last sample was collected, the cannula was removed, and participants were monitored throughout the process. All dietary and fluid intake was controlled and recorded during the PK visit.
[0083] A stable 3-day sleep record was taken before each PK visit to ensure a baseline sleep pattern for comparison during the supplementary phase.

[0085] 1 The height and weight reported during the telephone screening will be confirmed during the first visit. 2 Excluding height, 3 After sitting quietly for 5 minutes Result measurement Main results: Total melatonin uptake was measured via AUC0-8 in blood samples.
[0086] Secondary results: C via blood samples 最大 T via blood sample 最大 The study included changes in sleep quality as assessed by a sleep diary (T1 / 2 via blood sample), changes in sleep attack time as assessed by a consensus sleep diary (CSD-M), changes in sleep disturbances as assessed by a sleep diary, and the number and severity of adverse events as monitored by adverse events (AEs). result Demographic data This study recruited twenty-six participants, of whom twenty-four completed the pharmacokinetic (PK) component of Product 1 (Prosomnial) and twenty-three completed the PK component of Product 2 (Comparative). Among the participants who completed the PK component, 21 completed a 7-day sleep diary for both Product 1 (Prosomnial) and Product 2 (Comparative).
[0087] Because this study was a crossover design, there were no significant differences in characteristics between the groups at any point (Tables 3 and 4).

[0095] Sleep Diary There were no significant differences between the groups at baseline (Table 7). When considering the relative changes of each group relative to baseline, there were no significant differences between the groups for any measurement. Compared with baseline, the Prosomnial group showed significant changes in sleep latency, total sleep time, sleep quality, and perceived rest, while the comparison substance melatonin showed significant changes in perceived wakefulness and rest compared with baseline.
