Description

Technical Field

[0001] The present invention relates to the field of skin care products, in particular to an anti-aging plant extract composition and application thereof in anti-aging skin care products. Background Art

[0002] As we age, our metabolism slows and collagen is lost. Furthermore, uncontrollable environmental factors such as sunlight, air pollution, smoking, and pesticides increase the production of reactive oxygen species (ROS) in the body, accelerating skin aging. Anti-aging has become a hot topic. The mechanisms of aging have been extensively studied. The free radical theory of aging posits that degenerative changes during aging are caused by the harmful effects of free radicals produced during normal cellular metabolism. The aging process is the result of the accumulation of free radicals continuously produced by tissue cells. Free radicals are intermediate products of normal metabolism, possessing certain immune and signaling functions. Their highly reactive nature allows them to act destructively, oxidizing various substances within cells, damaging biological membranes, and even damaging normal cells and tissues. This can lead to a variety of skin health problems, including dry skin; decreased elasticity, thinning skin, and wrinkles; decreased sebaceous gland activity and secretion; pigmentation; and slower recovery from skin injuries and increased bruising.

[0003] The main active ingredients in current anti-aging products include fullerenes, superoxide dismutase, nerve growth factor, collagen, and epidermal growth factor. These ingredients, combined with anti-aging vitamins, minerals, and amino acids, promote cell metabolism and increase skin elasticity and radiance. Furthermore, a variety of anti-aging plant extract combinations have emerged. These extracts, such as those obtained by processing and extracting peony, gardenia, Astragalus membranaceus root, and Ligustrum lucidum seed, combine their active ingredients to scavenge superoxide anion free radicals and hydroxyl free radicals, exerting anti-aging effects.

[0004] The above-mentioned anti-aging active ingredients are expensive, and the anti-aging effects of Chinese herbal extracts are poor. Therefore, it is necessary to develop a plant extract composition that is safe, stable, and has good anti-aging effects. Summary of the Invention

[0076]

[0077] Table 5: Results of human skin patch tests on the anti-aging essence obtained in Application Examples 1-8 and Control Groups 1-7

[0078]

[0079]

[0080] As can be seen from Table 5, the anti-aging essences obtained in Application Examples 1-8 and the anti-aging essences obtained in Control Groups 1-7 of the present invention have no irritation to the skin.

[0081] 2. Antioxidant performance test:

[0082] Preparation of the sample solution: Weigh 0.08 g of the anti-aging essence obtained in the above application examples 1-8 and control groups 1-7, add 100 ml of distilled water and stir evenly to prepare a 0.8 mg / ml sample solution.

[0083] Hydroxyl free radical scavenging rate experiment

[0084] Reagents: 1.865 mmol / L phenanthroline solution in anhydrous ethanol, 0.2 mol / L pH 7.4 phosphate buffer, 1.865 mmol / L FeSO4·7H2O solution, 0.03% (v / v) H2O2, distilled water, and sample solution.

[0085] Method: Take 1.0mL of 1.865mmol / L phenanthroline anhydrous ethanol solution in a stoppered test tube, add 2mL of 0.2mol / L pH 7.4 phosphate buffer and 1mL of the sample solution, mix thoroughly, then add 1.0mL of 1.865mmol / L FeSO4·7H2O solution, mix again, and add 1.0mL The samples were added with 0.03% (v / v) H2O2 and placed in a constant temperature water bath at 37°C for 60 minutes to obtain a mixed solution. The absorbance value of each mixed solution was measured at 536 nm as As; the blank group was replaced with distilled water to measure the absorbance value Ab; the damaged group was replaced with distilled water to measure the absorbance value An. The hydroxyl radical scavenging rate of the antioxidant was calculated according to the following formula: Hydroxyl radical scavenging rate (%) = [(As-An) / (Ab-An)] × 100. The average value of three measurements was taken. The test results are shown in Table 6.

[0086] DPPH free radical scavenging rate experiment

[0087] Reagents: 0.0178mmol / L DPPH-anhydrous methanol solution, anhydrous ethanol, 0.8mg / ml of the above sample solution.

[0088] Method: 3 ml of a 0.0178 mmol / L DPPH-anhydrous methanol solution was placed in a cuvette. 3 ml of the sample solution was then added. The mixture was mixed and the absorbance was immediately measured at a wavelength of 517 nm, with the absorbance value recorded as Ai. The sample was then stored in the dark at 37°C for 30 minutes before the absorbance was measured again, with the absorbance value recorded as Aj. A blank control was prepared by adding only the DPPH-anhydrous methanol solution without the sample solution. The mixture was mixed and the absorbance was immediately measured at a wavelength of 517 nm, with the absorbance value recorded as Ac. The DPPH free radical scavenging rate was calculated as follows: DPPH free radical scavenging rate (%) = [1-(Ai-Aj) / Ac] × 100%. The average of three measurements was taken. The test results are shown in Table 6.

[0089] Table 6 Free radical scavenging rate test results

[0090]

[0091] As can be seen from Table 6, compared with Control Group 7 (which does not contain the anti-aging components of the present invention), the free radical scavenging rates of Application Examples 1-8 (containing the anti-aging components of the present invention) and Control Groups 1-6 (containing some anti-aging components) were significantly higher than those of Control Group 7, demonstrating significantly better anti-aging effects. This demonstrates that the medicinal plant extracts in the skin care products of the present invention have excellent free radical scavenging properties. Furthermore, the free radical scavenging rate of the skin care product in Application Example 1, which simultaneously incorporates three medicinal plant extracts, was higher than that of Control Groups 1-6, demonstrating that these three medicinal plant extracts synergistically enhance each other's effectiveness and provide enhanced anti-aging efficacy.

[0092] 3. Human skin test:

[0093] Pre-test treatment: 300 subjects with healthy, wrinkled skin, aged 35-45, were randomly divided into 15 groups of 20 each. The subjects were treated with the anti-aging essence prepared in Examples 1-8 and Control Groups 1-7. The subjects applied the test sample to their faces twice daily, morning and evening. During the experimental period, the subjects were prohibited from applying any other skincare products to the experimental areas. Testing was performed after 0 and 4 weeks of continuous use of the test sample.

[0094] Skin elasticity test: Skin elasticity was measured using the German CK company's MPA580 skin elasticity tester and a Reviscometer RV600 probe. Wrinkles and skin texture were measured using a skin analyzer, specifically the Visia skin analyzer. The data from each group of 20 people before and after using the corresponding application example and control product were calculated according to the formula:

[0095] Change rate = (average value of 20 people in each group after use - average value of 20 people in each group before use) / average value of 20 people in each group before use.

[0096] The data in Table 7 were obtained by calculation.

[0097] Table 7 Skin changes after using the essence of application examples 1-8 and control groups 1-7 for 4 weeks compared with before use

[0098]

[0099] As can be seen from the data in Table 7, the essence prepared using the plant extract composition provided by the present invention can effectively improve the area of skin wrinkles, reduce wrinkles, increase skin elasticity, and reduce skin texture, indicating that firmness and fineness are significantly improved.
