Description

Technical Field

[0001] This invention relates to the field of natural plant extract technology, and in particular to a tea oil plant extract composition with weight loss function and its preparation method. Background Technology

[0002] Camellia oil, a high-quality woody plant oil, is rich in unsaturated fatty acids, vitamin E, tea polyphenols, camelliaside, and other active ingredients, possessing physiological functions such as anti-oxidation, regulating blood lipids, and promoting fat metabolism. Regarding the application research of camellia oil extract in the health care field, its weight-loss effect when used alone is relatively limited, failing to meet people's demand for efficient weight loss. Furthermore, some weight-loss products containing camellia oil extract suffer from problems in their formulation design, including unreasonable ingredient combinations, low utilization rates of active ingredients, and complex preparation processes, further restricting their industrial application.

[0003] In the prior art, the invention patent application with publication number CN116327844A discloses a method for preparing a lipid-lowering and weight-loss tea oil composition. However, by combining tea oil and Eucommia ulmoides, a multi-target synergistic system is not formed, and the preparation process uses traditional reflux extraction, which results in the loss of active ingredients. Summary of the Invention

[0004] The purpose of this invention is to provide a tea oil plant extract composition with weight loss function and its preparation method. The multiple natural plant extracts work synergistically to inhibit fat absorption, promote fat decomposition, and regulate lipid metabolism. It has high safety and the preparation process is simple and can be mass-produced.

[0005] To achieve the above objectives, the present invention provides a tea oil plant extract composition with weight-loss function, comprising the following components in parts by weight: Tea oil extract 8-15 parts, green tea extract 5-10 parts, Garcinia cambogia extract 3-8 parts, lotus leaf extract 2-6 parts, Poria cocos extract 1-5 parts, hawthorn extract 1-4 parts, licorice extract 0.5-2 parts.

[0006] Preferably, it comprises the following components in parts by weight: 10-12 parts of tea oil extract, 7-9 parts of green tea extract, 5-7 parts of Garcinia Cambogia extract, 3-5 parts of lotus leaf extract, 2-4 parts of Poria cocos extract, 2-3 parts of hawthorn extract, and 1-1.5 parts of licorice extract.

[0007] Among them, the main active ingredients of tea oil extract are unsaturated fatty acids (oleic acid content greater than 85%), tea polyphenols, and camelliaside; the main active ingredients of green tea extract are tea polyphenols (catechins) and caffeine; the main active ingredient of Garcinia cambogia extract is hydroxycitric acid; the main active ingredients of lotus leaf extract are lotus leaf alkaloids and flavonoids; the main active ingredients of Poria cocos extract are Poria cocos polysaccharides and triterpenoids; the main active ingredients of hawthorn extract are hawthorn flavonoids and organic acids; and the main active ingredients of licorice extract are glycyrrhizic acid and glycyrrhetinic acid.

[0008] High-purity oleic acid can inhibit the activity of acetyl-CoA carboxylase in the liver, reducing triglyceride synthesis, while promoting the secretion of leptin from adipocytes, thus reducing appetite. The unsaturated fatty acid structure can increase cell membrane permeability, making it easier for catechins and hydroxycitric acid to enter adipocytes. Catechins inhibit the activity of lipase in the intestine, reducing the breakdown and absorption of fat from food. Hydroxycitric acid competitively binds to ATP-citrate lyase, preventing the conversion of acetyl-CoA into fatty acids, further disrupting the fat synthesis pathway. The core regulatory effect of tea oil extract lies in avoiding an excessively high proportion that competes with Garcinia Cambogia extract for fat synthesis enzyme targets, and avoiding an excessively low proportion that weakens its effect on increasing cell membrane permeability, thus forming a dual blocking effect of inhibiting absorption and blocking synthesis.

[0009] Based on this, glycyrrhizic acid moderates the irritation and improves safety, while the active ingredients of lotus leaf, poria cocos and hawthorn are responsible for intestinal regulation and lipid metabolism optimization, constructing a three-dimensional weight loss system that inhibits absorption, blocks synthesis and promotes decomposition.

[0010] This invention also provides a method for preparing a tea oil plant extract composition with weight loss function, comprising the following steps: S1. Raw material pretreatment: Remove impurities from camellia seeds, green tea, Garcinia cambogia peel, lotus leaf, Poria cocos, hawthorn, and licorice, dry them, pulverize them, and pass them through an 80-100 mesh sieve to obtain raw material powder. S2. Extract Preparation: Supercritical CO2 extraction was used to extract tea oil from camellia seed powder, yielding a tea oil extract with an oleic acid content greater than 85%. Ethanol reflux extraction was used to collect extracts from green tea powder, followed by filtration, concentration, and drying to obtain a green tea extract with a catechin content greater than 60%. Microwave-assisted extraction was used to collect extracts from lotus leaf powder, followed by filtration, concentration, and drying to obtain a lotus leaf extract. Water extraction and alcohol precipitation were used to collect extracts from Poria cocos powder, hawthorn powder, licorice powder, and Garcinia cambogia peel powder, followed by filtration, concentration, and drying to obtain Poria cocos extract, hawthorn extract, licorice extract, and Garcinia cambogia extract with a hydroxycitric acid content greater than 50%. S3. Mixing and Granulation: Mix tea oil extract, green tea extract powder, Garcinia cambogia extract powder, lotus leaf extract powder, Poria cocos extract powder, hawthorn extract powder, and licorice extract powder evenly according to the weight ratio to obtain a mixture.

The extract was collected to obtain camellia oil extract.

[0013] Preferably, in step S2, the preparation method of the green tea extract is as follows: Add green tea powder to a 70%–80% ethanol solution at a material-to-liquid ratio of 1:10–15, and reflux extract at 80–85 degrees Celsius 2–3 times, with each extraction lasting 1–1.5 hours. Combine the extracts, concentrate under reduced pressure until no alcohol odor remains, and then spray dry to obtain green tea extract powder.

[0014] Preferably, the concentration temperature of the vacuum concentration is 50~65 degrees Celsius and the vacuum degree is -0.08~-0.09 MPa, and the inlet air temperature of the spray drying is 180~200 degrees Celsius and the outlet air temperature is 75~90 degrees Celsius.

[0015] Preferably, in step S2, the lotus leaf extract is prepared as follows: Lotus leaf powder was added to deionized water at a material-to-liquid ratio of 1:10-14. Microwave-assisted extraction was performed with a microwave power of 500-600W, an extraction temperature of 70-75 degrees Celsius, and an extraction time of 30-40 minutes. The extraction was repeated 1-2 times. The extracts were combined, filtered at 60-65 degrees Celsius, and concentrated under reduced pressure to a relative density of 1.15-1.20. The extracts were then spray-dried to obtain lotus leaf extract powder.

[0016] Preferably, in S2, the preparation method of the Garcinia Cambogia extract is as follows: At a material-to-liquid ratio of 1:8-12, Garcinia Cambogia pericarp powder was added to deionized water and extracted 2-3 times at 90-95°C, with each extraction lasting 1.5-2 hours. The extracts were combined, and ethanol was added until the ethanol volume fraction reached 60%-70%. The mixture was allowed to stand for 12-16 hours, then centrifuged at 3000-4000 r / min for 10-15 minutes. The supernatant was collected and concentrated under reduced pressure at 60-65°C to a relative density of 1.20-1.25. The mixture was then vacuum dried at 55-65°C and a vacuum degree of -0.09--0.1 MPa, and pulverized to obtain Garcinia Cambogia extract powder.

[0017] Preferably, in S3, the adhesive is a 5-10% hydroxypropyl methylcellulose ethanol solution, and the amount of adhesive used is 8-12% of the total weight of the mixture.

[0018] Therefore, the present invention employs the above-mentioned tea oil plant extract composition with weight loss function and its preparation method, and the beneficial effects are as follows: (1) Significant weight loss effect and strong synergistic effect: The composition of the present invention uses tea oil extract as the main active ingredient, combined with various natural plant extracts such as green tea extract, Garcinia cambogia extract, and lotus leaf extract. Each component exerts its weight loss effect through different mechanisms of action, such as inhibiting fat absorption, inhibiting fat synthesis, promoting fat decomposition, and regulating lipid metabolism, forming a synergistic effect and significantly enhancing the weight loss effect.

[0034] Example 2 A tea oil plant extract composition with weight loss function comprises the following weight groups: 8 parts tea oil extract, 8 parts green tea extract, 6 parts Garcinia Cambogia extract, 2 parts lotus leaf extract, 1 part Poria cocos extract, 1 part hawthorn extract, and 0.5 parts licorice extract.

[0035] Its preparation method is the same as that in Example 1.

[0036] Example 3 A tea oil plant extract composition with weight loss function comprises the following weight groups: 15 parts tea oil extract, 8 parts green tea extract, 6 parts Garcinia Cambogia extract, 4 parts lotus leaf extract, 3 parts Poria cocos extract, 5 parts hawthorn extract, and 1 part licorice extract.

[0037] Its preparation method is the same as that in Example 1.

[0038] Example 4 A tea oil plant extract composition with weight loss function comprises the following weight groups: 13 parts tea oil extract, 8 parts green tea extract, 6 parts Garcinia Cambogia extract, 2 parts lotus leaf extract, 1 part Poria cocos extract, 2.5 parts hawthorn extract, and 1.3 parts licorice extract.

[0039] Its preparation method is the same as that in Example 1.

[0040] Comparative Example 1 A tea oil extract, the preparation method of which is basically the same as that in Example 1, except that green tea extract, Garcinia Cambogia extract, lotus leaf extract, Poria cocos extract, hawthorn extract, and licorice extract are not added.

[0041] Comparative Example 2 A tea oil plant extract composition with weight loss function differs from Example 1 in that the tea oil extract is replaced with 16 parts and the green tea extract is replaced with 4 parts in the raw material components.

[0042] Comparative Example 3 A tea oil plant extract composition with weight loss function differs from Example 1 in that the tea oil extract in the raw material components is replaced with 7 parts and the green tea extract is replaced with 11 parts.

[0043] Test 1. Animal experiments verifying the weight loss effect: Eighty male SD rats, weighing 180-220g, were purchased from an experimental animal center. After one week of acclimatization feeding, they were randomly divided into eight groups of ten rats each: blank control group, control group 1, control group 2, control group 3, experimental group 1, experimental group 2, experimental group 3, and experimental group 4. The experimental groups used granules prepared according to Examples 1-4, the control groups used granules prepared according to Comparative Examples 1-3, and the blank control group used physiological saline.

[0044] Except for the blank control group, which was given a normal diet, all other groups were given a high-fat diet (45% fat content) to establish an obesity model and were fed continuously for 4 weeks. After successful modeling, the blank control group was given physiological saline by gavage, while experimental groups 1-4 and control groups 1-3 were given the corresponding granular suspension by gavage (dose of 100 mg / kg body weight per day) once a day for 8 weeks.

[0045] The rats were weighed weekly, and the weight loss rate was calculated. The results are shown in Table 1.

[0046] Table 1. Statistical results of weight loss rate

[0047] Table 1 shows that the weight loss rate in the blank control group and control group 1 was close to 0 (0.05%~0.65%). Comparative group 1, with its single tea oil extract, had no weight loss effect. Comparative groups 2 and 3, due to unreasonable ingredient combinations, had weaker overall effects than the experimental group. Increasing the proportion of tea oil and slightly adjusting the proportions of other active ingredients led to significant differences in synergistic efficiency. The weight loss rate in each group gradually increased with the extension of the administration time, with a faster increase in weeks 1-4, representing the initiation period of fat decomposition. The rate of increase slowed down in weeks 5-8, and body fat tended to stabilize, verifying that the composition has a significant synergistic weight loss effect.

[0048] 2. Acute toxicity test verification: Forty mice (half male and half female, weighing 18-22g) were used and acclimatized for 3 days. They were randomly divided into two groups of 20 mice each (10 males and 10 females): the experimental group was given the granules prepared in Example 1, which were prepared into a granule suspension with a concentration of 200mg / mL using physiological saline and administered by gavage (dose of 4000mg / kg body weight per day for both groups), while the blank control group was given an equal volume of physiological saline by gavage.

[0049] After gavage, the mice were observed for 14 consecutive days. The general condition (mental state, diet, water intake, defecation, activity level), weight changes and mortality were recorded daily. The results are shown in Table 2.

[0050] Table 2 Statistical results of acute toxicity

[0051] Table 2 shows that no mice died in the experimental group within 14 days, and their general condition was no different from that of the blank control group. Therefore, the LD50 was determined to be... 50 >2000mg / kg.

[0052] Therefore, the present invention uses the above-mentioned tea oil plant extract composition with weight loss function and its preparation method. The synergistic effect of multiple natural plant extracts can inhibit fat absorption, promote fat decomposition, regulate lipid metabolism, and has high safety. Moreover, the preparation process is simple and can be mass-produced.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
