[0012] Furthermore, the multi-effect skin care herbal extract composition is obtained by premixing each extract at 40~50℃ for 20 min, and then dispersing it at low speed of 300~500 rpm for 30 min.

[0013] Furthermore, the extraction process steps of the water shield extract are as follows: Step 1: Raw material pretreatment Remove impurities from fresh or dried water shield raw materials, wash them, dry them at a low temperature of 40~50℃ until the moisture content is ≤10%, and then crush them through a 40~60 mesh sieve; Step 2: Low-temperature complex enzymatic hydrolysis Add purified water at a material-to-liquid ratio of 1:(12~18), adjust the pH to 4.8~5.5, add a compound enzyme (cellulase: pectinase = 1:1, the total enzyme content is 0.8%~1.5% of the raw material mass), and enzymatically hydrolyze at 45~52℃ for 1.5~3.0 h to break the cell wall and release polysaccharides and gums. Step 3: Segmented hot water extraction After enzymatic hydrolysis, the temperature is raised to 75~85℃ for two-stage hot water extraction: first extraction: material-to-liquid ratio 1:(10~12), extraction time 1.0~1.5 h; second extraction: material-to-liquid ratio 1:(8~10), extraction time 0.8~1.2 h, and the extracts are combined. Step 4: Membrane separation and purification Ultrafiltration membrane (molecular weight cutoff 10~30 kDa) is used for separation to remove small molecule impurities and some pigments, while retaining large molecule polysaccharides and colloidal active components; Step 5: Vacuum low-temperature concentration and spray drying The filtrate was concentrated under vacuum at a temperature below 55°C to a solid content of 15% to 25%, and then spray-dried at an inlet air temperature of 140 to 165°C and an outlet air temperature of 75 to 90°C to obtain water shield extract powder.

[0014] Furthermore, the extraction process steps of the Scutellaria baicalensis extract are as follows: Step 1: Raw material pretreatment After washing, the Scutellaria baicalensis root is dried at a temperature below 60°C, then pulverized and passed through a 40-mesh sieve. Step 2: Eutectic solvent-assisted alcohol extraction Prepare a green eutectic solvent (choline chloride-lactic acid system, molar ratio 1:2), add 5%~15% by volume to 50%~70% ethanol, extract at a material-liquid ratio of 1:(8~12), and perform ultrasonic-assisted extraction at 60~75℃ for 30~60 min. Step 3: Reflux and secondary extraction The residue was then refluxed with 50%–70% ethanol 1–2 times, each time for 1.0–1.5 h, and the extracts were combined. Step 4: Reduce pressure to recover ethanol Ethanol was recovered to a content of less than 10% under conditions of 45~55℃ and -0.08~-0.095 MPa. Step 5: Macroporous resin enrichment Adsorption was performed using AB-8 or D101 macroporous resin, with the sample loading flow rate controlled at 1.0~2.0 BV / h. After washing with water to remove impurities, the sample was eluted with a gradient of 50%~80% ethanol to collect the flavonoid-rich fraction of Scutellaria baicalensis. Step 6: Concentration and Drying The eluent was concentrated under reduced pressure and then dried under low temperature vacuum or spray-dried to obtain Scutellaria baicalensis extract powder.

[0015] Furthermore, the extraction process steps of the ginseng extract are as follows: Step 1: Raw material pretreatment After ginseng slices are dried at low temperature, they are pulverized and passed through a 20-40 mesh sieve. Step 2: Gradient alcohol extraction Use 30%~60% ethanol as the extraction solvent, with a solid-liquid ratio of 1:(10~15), and reflux extraction at 50~65℃ for 1.5~2.5 h, for 2 extractions; Step 3: Ultrasonic Enhanced Extraction The second extraction can be performed with ultrasound assistance, using an ultrasound power of 200-500 W, a temperature of 45-60℃, and a time of 20-40 min, to promote saponin release. Step 4: Membrane fractionation purification After combining the extracts, the extracts are fractionated by nanofiltration or ultrafiltration to preferentially retain saponins and polysaccharide complex active components with relatively high molecular weight, while removing some pigments and small molecule impurities. Step 5: Low-temperature concentration and freeze-drying After concentration at below 50°C, the extract was pre-frozen at -40°C and then freeze-dried under vacuum to obtain a highly active ginseng extract powder.

[0016] Furthermore, the extraction process steps of the Atractylodes lancea extract include: Step 1: Raw material pretreatment After cleaning, the rhizome of Atractylodes lancea is dried at low temperature and then pulverized and passed through a 20-40 mesh sieve. Step 2: Supercritical CO2 extraction of volatile components Supercritical CO2 extraction was employed at a pressure of 20–30 MPa, a temperature of 35–45 °C, a CO2 flow rate of 15–30 kg / h, and an extraction time of 1.5–3 h. 5%–10% ethanol was used as an entrainer to improve the extraction efficiency of polar components. Step 3: Secondary extraction with ethanol The residue was then refluxed with 60%~80% ethanol at a material-to-liquid ratio of 1:(8~12) 1~2 times, each time for 1~1.5 h, to obtain Atractylodes polyphenols and auxiliary active ingredients; Step 4: Low-temperature solvent removal and standardization After combining the extracts, the concentration was carried out under reduced pressure to control the final volatile oil content and total solids content. If necessary, microencapsulation or cyclodextrin inclusion treatment was performed to improve stability and odor compatibility.

[0017] Furthermore, the extraction process of the licorice extract includes: Step 1: Raw material pretreatment Licorice root and stem are washed, dried, and pulverized through a 40-mesh sieve; Step 2: Acid-base regulation - combined water and alcohol extraction Add the raw material to 40%~60% ethanol at a material-to-liquid ratio of 1:(10~15), add 0.05%~0.20% citric acid or lactic acid to adjust the pH of the system to 5.0~6.0, and reflux extract at 55~70℃ for 1~2 h; Step 3: Ultrasonic-assisted extraction Ultrasound was applied during the extraction process at a power of 150-400 W for 20-45 min to enhance the dissolution of glycyrrhizic acid and flavonoids. Step 4: Macroporous resin enrichment and decolorization Adsorption was performed using AB-8, HPD-100 or XAD series macroporous resins. Sugar impurities were first removed by washing with water, and then eluted with 40%~75% ethanol to obtain a component rich in glycyrrhizic acid and flavonoids. Step 5: Concentration and Drying The licorice extract was obtained by concentration under reduced pressure and vacuum drying.

[0018] Furthermore, this invention also discloses the application of a multi-effect skin care herbal extract composition in the preparation of cosmetics, wherein the herbal extract composition accounts for 1.5-12% by mass in the cosmetics, and the remainder is conventional cosmetic excipient matrix.

[0019] Furthermore, the herbal extract composition constitutes 2-6% by mass in the cosmetic; the dosage forms of the cosmetic include, but are not limited to, moisturizing and repairing lotions, multi-effect repairing serums, repairing creams, soothing and repairing masks, oil-controlling gels, and anti-allergic soothing sprays.

[0020] By employing the above technical solution, the present invention has the following beneficial technical effects: 1) This invention utilizes targeted and innovative extraction of water shield, scutellaria baicalensis, ginseng, atractylodes lancea, and licorice, followed by scientific compounding, to obtain a multi-effect skincare herbal extract composition suitable for cosmetics.

[0022] To better illustrate the present invention, the following detailed description is provided in conjunction with specific embodiments. However, these specific embodiments are merely for illustrative purposes and are not intended to limit the scope of the invention.

[0023] With the increasing demand from consumers for gentle, safe, and natural cosmetics, skincare active ingredients derived from traditional Chinese medicine have gained widespread attention due to their high biocompatibility, low irritation, and multi-target effects. Existing single-plant extracts often suffer from narrow scope of action, limited efficacy, insufficient stability, or insignificant synergistic effects when combined with other ingredients. Especially in multi-functional skincare scenarios, a single ingredient struggles to simultaneously address multiple aspects such as moisturizing, soothing, anti-oxidation, oil control, and skin barrier repair.

[0024] This invention relates to the field of natural plant active substance extraction and cosmetic technology, specifically to a multi-effect skin care herbal extract composition composed of water shield extract, scutellaria baicalensis extract, ginseng extract, atractylodes lancea extract, and licorice extract, and its application in cosmetics such as moisturizing, soothing, anti-oxidation, repairing, oil control, and improving skin texture.

[0025] Water shield (Brasenia schreberi) is rich in polysaccharides and pectin, possessing excellent film-forming and moisturizing potential; Scutellaria baicalensis contains baicalin and baicalein, exhibiting antioxidant and soothing effects; Ginseng contains ginsenosides, possessing repair-promoting and anti-aging value; Atractylodes lancea contains volatile components and sesquiterpenes, offering both refreshing oil control and skin conditioning effects; Licorice contains glycyrrhizic acid and glycyrrhizin flavonoids, providing soothing, anti-inflammatory, and skin-conditioning effects. Through rational extraction, targeted enrichment, and scientific compounding, multi-component and multi-pathway synergy can be achieved, resulting in a stronger multi-effect skincare regimen.

[0026] This invention aims to provide a multi-effect skin care herbal extract composition and its preparation method. By selectively and innovatively extracting water shield, scutellaria baicalensis, ginseng, atractylodes lancea, and licorice, a highly active, low-impurity plant extract suitable for cosmetic applications is obtained. Through scientific compounding, the synergistic effects of moisturizing, soothing, anti-oxidation, repairing, oil control, and improving skin texture are achieved.

[0027] The multi-effect skincare herbal extract composition of this invention consists of five extracts: water shield extract; scutellaria baicalensis extract; ginseng extract; atractylodes lancea extract; and licorice extract. Each extract is prepared using a specific innovative extraction process, and then blended in a certain proportion to obtain the multi-effect skincare herbal extract composition.

[0028] 1. Innovative extraction process of water shield extract Water shield is rich in polysaccharides, colloids, amino acids and a small amount of phenolic substances. It is suitable for low-temperature enzymatic hydrolysis-segmented water extraction-membrane separation-low-temperature concentration process to maximize the preservation of its natural polysaccharides and moisturizing film-forming activities.

[0029] Process steps: Step 1: Raw material pretreatment Remove impurities from fresh or dried water shield raw materials, wash them, and dry them at a low temperature of 40~50℃ until the moisture content is ≤10%. Then, crush them and pass them through a 40~60 mesh sieve.

[0030] Step 2: Low-temperature complex enzymatic hydrolysis Add purified water at a material-to-liquid ratio of 1:(12~18), adjust the pH to 4.8~5.5, add a compound enzyme (cellulase: pectinase = 1:1, the total enzyme content is 0.8%~1.5% of the raw material mass), and enzymatically hydrolyze at 45~52℃ for 1.5~3.0 h to break the cell wall and release polysaccharides and gums.

[0031] Step 3: Segmented hot water extraction After enzymatic hydrolysis, the temperature is raised to 75-85℃ for two-stage hot water extraction: First extraction: material-to-liquid ratio 1:(10~12), extraction for 1.0~1.5 h; Second extraction: material-to-liquid ratio 1:(8~10), extraction for 0.8~1.2 h.

[0032] Combine the extracts.

[0033] Step 4: Membrane separation and purification Ultrafiltration membranes (with a molecular weight cutoff of 10-30 kDa) are used for separation to remove small molecule impurities and some pigments, while retaining large molecule polysaccharides and colloidal active components.

[0034] Step 5: Vacuum low-temperature concentration and spray drying The filtrate was concentrated under vacuum at a temperature below 55°C to a solid content of 15% to 25%, and then spray-dried at an inlet air temperature of 140 to 165°C and an outlet air temperature of 75 to 90°C to obtain water shield extract powder.

[0035] Innovations: Low-temperature compound enzymatic hydrolysis combined with segmented hot water extraction is used to increase the release rate of water shield polysaccharides; ultrafiltration membrane separation is used to reduce low-molecular-weight impurities and improve the applicability to cosmetics; low-temperature concentration and spray drying conditions are optimized to reduce the loss of heat-sensitive components.

[0036] 2. Innovative extraction process of Scutellaria baicalensis extract The main active components of Scutellaria baicalensis are flavonoids such as baicalin, baicalein, and wogonin. The method of "low-alcohol extraction-deep eutectic assisted extraction-macroporous resin enrichment" is suitable for improving the yield and purity of total flavonoids.

[0037] Process steps: Step 1: Raw material pretreatment After washing, the Scutellaria baicalensis root is dried at a temperature below 60°C and then pulverized and passed through a 40-mesh sieve.

[0038] Step 2: Eutectic solvent-assisted alcohol extraction Prepare a green eutectic solvent (such as a choline chloride-lactic acid system, molar ratio 1:2), add it to 50%-70% ethanol at a volume fraction of 5%-15%, and extract at a material-to-liquid ratio of 1:(8-12). Extract with ultrasound at 60-75℃ for 30-60 min.

[0039] Step 3: Reflux and secondary extraction The residue was then refluxed with 50%–70% ethanol 1–2 times, each time for 1.0–1.5 h, and the extracts were combined.

[0040] Step 4: Reduce pressure to recover ethanol Ethanol was recovered to a content of less than 10% under conditions of 45~55℃ and -0.08~-0.095 MPa.

[0041] Step 5: Macroporous resin enrichment Adsorption was performed using AB-8 or D101 macroporous resins, with the sample loading flow rate controlled at 1.0~2.0 BV / h. After washing with water to remove impurities, the sample was eluted with a gradient of 50%~80% ethanol to collect the flavonoid-rich fraction of Scutellaria baicalensis.

[0042] Step 6: Concentration and Drying The eluent was concentrated under reduced pressure and then dried under low temperature vacuum or spray-dried to obtain Scutellaria baicalensis extract powder.

[0043] Innovations include: using eutectic solvent-assisted extraction to improve flavonoid dissolution efficiency; combining ultrasound and reflux to shorten extraction time; and using macroporous resin for enrichment to improve flavonoid purity and compatibility stability.

[0044] 3. Innovative extraction process of ginseng extract The main active components in ginseng are ginsenosides, along with polysaccharides, amino acids, and small amounts of volatile compounds. To balance the activity of both saponins and polysaccharides, a low-temperature directional extraction and membrane separation process is employed.

[0045] Process steps: Step 1: Raw material pretreatment After ginseng is sliced, it is dried at low temperature and then pulverized and passed through a 20-40 mesh sieve.

[0046] Step 2: Gradient alcohol extraction Use 30%~60% ethanol as the extraction solvent, with a solid-liquid ratio of 1:(10~15), and reflux extraction at 50~65℃ for 1.5~2.5 h, for a total of 2 extractions.

[0047] Step 3: Ultrasonic Enhanced Extraction The second extraction can be performed with ultrasound assistance, using an ultrasound power of 200-500 W, a temperature of 45-60℃, and a time of 20-40 min, to promote saponin release.

[0048] Step 4: Membrane fractionation purification After merging the extracts, the fractions are separated by nanofiltration or ultrafiltration to preferentially retain the saponins and polysaccharide complex active components with relatively high molecular weight, while removing some pigments and small molecule impurities.

[0049] Step 5: Low-temperature concentration and freeze-drying After concentration at below 50°C, the extract was pre-frozen at -40°C and then freeze-dried under vacuum to obtain a highly active ginseng extract powder.

[0050] Innovations: Gradient alcohol extraction combined with ultrasonic enhancement improves saponin extraction rate; membrane fractionation purification improves component uniformity; freeze drying preserves ginseng's thermosensitive activity.

[0051] 4. Innovative extraction process of Atractylodes lancea extract The main active ingredients in Atractylodes lancea include atractylone, atractylol, and volatile oil components, which have oil-controlling, antibacterial, and skin-conditioning effects. The processing method must balance the retention of volatile components with the removal of irritating impurities.

[0052] Process steps: Step 1: Raw material pretreatment After cleaning, the rhizome of Atractylodes lancea is dried at low temperature and then pulverized and passed through a 20-40 mesh sieve.

[0053] Step 2: Supercritical CO2 extraction of volatile components Supercritical CO2 extraction was employed at a pressure of 20–30 MPa, a temperature of 35–45 °C, a CO2 flow rate of 15–30 kg / h, and an extraction time of 1.5–3 h. 5%–10% ethanol was used as an entrainer to improve the extraction efficiency of polar components.

[0054] Step 3: Secondary extraction with ethanol The residue was then refluxed with 60%~80% ethanol at a material-to-liquid ratio of 1:(8~12) 1~2 times, each time for 1~1.5 h, to obtain Atractylodes polyphenols and auxiliary active ingredients.

[0055] Step 4: Low-temperature solvent removal and standardization After combining the extracts, the concentration was carried out under reduced pressure to control the final volatile oil content and total solids content. If necessary, microencapsulation or cyclodextrin inclusion treatment was performed to improve stability and odor compatibility.

[0056] Innovations: Supercritical CO2 is used to preferentially extract volatile active ingredients, avoiding high-temperature loss; secondary ethanol extraction retains auxiliary active ingredients; further encapsulation can be performed to improve applicability in cosmetics.

[0057] 5. Innovative extraction process of licorice extract The main active ingredients in licorice are glycyrrhizic acid, glycyrrhetinic acid, and glycyrrhizin flavonoids, which have soothing, anti-inflammatory, and antioxidant effects.

[0058] Process steps: Step 1: Raw material pretreatment Licorice root and stem are washed, dried, and pulverized through a 40-mesh sieve.

[0059] Step 2: Acid-base regulation - combined water and alcohol extraction Add the raw material to 40%~60% ethanol at a material-to-liquid ratio of 1:(10~15), add 0.05%~0.20% citric acid or lactic acid to adjust the pH of the system to 5.0~6.0, and reflux extract at 55~70℃ for 1~2 h.

[0060] Step 3: Ultrasonic-assisted extraction Ultrasound was applied during the extraction process at a power of 150-400 W for 20-45 min to enhance the dissolution of glycyrrhizic acid and flavonoids.

[0061] Step 4: Macroporous resin enrichment and decolorization Adsorption was performed using AB-8, HPD-100 or XAD series macroporous resins. Sugar impurities were first removed by washing with water, and then eluted with 40%~75% ethanol to obtain a component rich in glycyrrhizic acid and flavonoids.

[0062] Step 5: Concentration and Drying The licorice extract was obtained by concentration under reduced pressure and vacuum drying.

[0063] Innovations: The acid-base micro-regulation water-alcohol extraction method improves the extraction efficiency of glycyrrhizic acid; the ultrasonic-assisted resin enrichment method balances purity and yield; and it is more suitable for mild and soothing applications in cosmetics.

[0064] The five extracts mentioned above possess the theoretical principle of synergistic effect of multiple skin care benefits. The synergistic effect of the multi-effect skin care composition of this invention mainly originates from the following mechanisms: (1) Synergistic effect of moisturizing and repair Water shield extract, rich in polysaccharides and colloidal components, can form a flexible moisturizing film on the skin surface, reducing transepidermal water loss (TEWL); the polysaccharides and saponins in ginseng extract can promote barrier repair and stratum corneum hydration; licorice extract helps soothe micro-inflammation caused by dryness and improves barrier stability. The combination of these three can form a closed loop of "moisturizing-repairing-soothing".

[0065] (2) Antioxidant synergy Flavonoids, ginsenosides, and licorice flavonoids in Scutellaria baicalensis all have the effect of scavenging free radicals and inhibiting lipid peroxidation; Polysaccharides from water shield can reduce oxidative stress exposure through protective film formation; and synergistic effects can enhance the skin's antioxidant defense system.

[0066] (3) Synergistic effect of soothing and anti-stimulation Baicalin and glycyrrhizic acid have typical soothing activities and can reduce redness and discomfort caused by external stimuli; the volatile components of Atractylodes lancea have an auxiliary effect on skin condition regulation and microecological balance; the combination can enhance the gentle and soothing experience of cosmetics.

[0067] (4) Oil control and skin cleansing synergistic effect Atractylodes lancea extract has good oil-controlling and skin-conditioning effects; Scutellaria baicalensis extract has the potential to improve sebum oxidation and oily environment; when combined with licorice, water shield, and ginseng, it can control oil while avoiding excessive dryness.

[0068] (5) Signal path coordination Scutellaria baicalensis flavonoids, glycyrrhizic acid, and ginsenosides can collectively influence pathways related to inflammatory responses, oxidative stress, and skin repair, such as NF-κB, MAPK, and Nrf2, thereby enhancing overall skincare efficacy.

[0069] In the herbal extract composition of the present invention, the preferred mass fraction ranges of each component are as follows: Water shield extract: 10-35 parts; Scutellaria baicalensis extract: 10-30 parts; Ginseng extract: 10-25 parts; Atractylodes lancea extract: 5-20 parts; Licorice extract: 10-30 parts When the total mass of the above five extracts is 100 parts, it can also be converted into their respective mass percentages.

[0070] The composition of the present invention can be applied to a variety of cosmetic systems, with an addition range of 0.2-8%, preferably 0.2-5%; or 0.5-3%.

[0071] The amounts added in different dosage forms of cosmetics are as follows: Toner / Serum: 0.2-5%; Lotion / Cream: 0.5-5%; Face Mask: 0.5-8%; Cleanser: 0.1-2%; Body Lotion and Repairing Skincare Products: 0.5-5%.

[0072] The following are examples of compounding processes for multi-effect skincare herbal extract compositions. The units for the following weight parts can be g or kg.

[0073] Example 1 Weigh out the following amounts by weight: 20 parts of water shield extract, 20 parts of scutellaria baicalensis extract, 20 parts of ginseng extract, 10 parts of atractylodes lancea extract, and 30 parts of licorice extract.

[0075] Key points of the process: This embodiment uses isothermal low-shear mixing, which is suitable for use in conventional aqueous, emulsion and mask systems.

[0076] Example 2 Weigh out the following amounts by weight: 25 parts of water shield extract, 20 parts of scutellaria baicalensis extract, 18 parts of ginseng extract, 12 parts of atractylodes lancea extract, and 25 parts of licorice extract.
