Background
With the aging, the body functions are reduced, the skin epidermis tissue is dried and thinned, collagen and elastin are gradually lost, the fine mesh structure formed by interweaving collagen fibers and elastic fibers is damaged, wrinkles with different thicknesses can occur, and besides the natural aging of the body skin, many factors in the environment can accelerate the skin aging process, such as excessive sugar intake, ultraviolet radiation, bad life style and the like. Based on the factors influencing skin aging, active substances with functions of resisting saccharification, resisting oxidization, resisting photoaging, promoting skin repair and the like are of great significance for resisting skin aging.
The collagen has the stretching capability, can keep skin elasticity and promote cell growth, can play roles in moisturizing, repairing, resisting wrinkles and the like when being applied to skin care products, and has good biodegradability and biological cosmetology, so that the collagen is also increasingly applied to skin care products.
The ancient magnolia-assuo fruit is a fruit growing in the tropical rain forest of North Amazon of Brazil. Its fruit contains rich vitamins, cellulose and amino acids, and is a natural antioxidant. The natural grease similar to butter can be extracted from seeds, has rich vitamins (especially vitamin A and vitamin C), mineral substances, amino acids, fatty acids and flavonoids, has great benefits to human bodies, can lead the skin to be fine, moist and smooth after being smeared for a long time, has excellent moisturizing and skin repairing promoting effects, has good absorption to ultraviolet rays, has no stimulation to the skin, has good safety, can effectively absorb the ultraviolet rays in sunlight, has a certain nursing effect on preventing sunburn and redness of the skin after sun, and is an unprecedented food material and natural skin care product for local people.
The kapok extract is rich in triterpene components and flavonoid compounds, can remove free radicals, promote the synthesis of aquaporin 3 and hyaluronic acid, rapidly supplement moisture for skin cells, improve skin elasticity, and repair fine wrinkles. Meanwhile, the kapok is used as a traditional Chinese medicine component, has sweet and cool taste, has the effects of clearing heat and promoting diuresis, removing toxicity and stopping bleeding, and has certain anti-inflammatory and repairing effects after being externally applied.

Test example 1
Antioxidant test
DPPH radical scavenging ability evaluation: the ability to scavenge DPPH (1, 1-diphenyl-2-trinitrophenylhydrazine) free radical is the antioxidant ability of the reactive species to some extent. The higher the free radical scavenging rate, the stronger the antioxidant capacity and the stronger the anti-aging capacity. Thus, the anti-aging effect of the anti-aging composition can be judged by studying the DPPH radical scavenging ability of the composition.
The compositions prepared in examples and comparative examples were diluted with DMSO to a test sample of 2% by mass, and the following tests were performed:
Adding 2.0mL of DPPH test solution with the mass concentration of 45.8mg/L and a sample to be tested into a test tube, supplementing the total volume to 3mL by absolute ethyl alcohol, shaking uniformly, carrying out light-shielding reaction for 30min, and measuring absorbance at 517nm wavelength by using A1 cm cuvette, and marking as A10; adding 2mL of absolute ethyl alcohol and a sample to be detected with a corresponding volume into a test tube, supplementing the total volume to 3mL by using the absolute ethyl alcohol, and recording the measured absorbance as A11; adding 2mL of DPPH test solution and 1mL of absolute ethyl alcohol into the test tube, recording the measured absorbance as A12, and calculating the clearance (Y') of the solution to be tested to DPPH free radicals;
The calculation formula of the DPPH free radical clearance is as follows:
wherein A 10 is the absorbance value of the system after DPPH is removed by the sample to be detected, A 11 is the absorbance value of the system after DPPH is removed by the sample blank control, and A 12 is the absorbance value of the reaction system before adding the medicine.
The test results are shown in Table 1.

Taking out each sample solution, detecting the sample solution by using an enzyme-labeled instrument, and recording the fluorescence absorption value, wherein the fluorescence excitation/emission wavelength is 370/440 nm. 3 replicates were made for each sample and the results averaged, wherein AEGs inhibition was calculated using the following formula:

TABLE 1
According to the table data, when the multiple-effect composition adopts recombinant collagen, guo's-Apostigma nano capsule, supermolecule kapok and supermolecule carnosine to be matched according to a specific proportion, the four raw materials act synergistically to jointly promote the effects of antioxidation, saccharification resistance and moisture preservation, and the effect is optimal.
From examples 1 and 4-5, it is known that the antioxidant, anti-glycation and moisturizing effects are affected when the amount of the ancient apo-su fruit nanocapsules, the supramolecular kapok or the supramolecular carnosine in the composition is too much or too little; from examples 1 and 6, acetone is used as a solvent in the preparation of the gupo-assuo nanocapsules, the activity is best, the bioavailability is high, ethanol is used instead, and the skin care effect is affected to a certain extent.
From example 1 and comparative examples 1 to 3, it is understood that when crude oil of ancient hackberry, crude extract of kapok and crude carnosine are directly used as raw materials, the biological activity of the effective molecules in the multi-effect composition is reduced, and the effects of antioxidation, anti-glycation and moisture preservation are greatly reduced.
From example 1, comparative examples 4-7, it is apparent that the antioxidant, anti-glycation and moisturizing efficacy of the composition is greatly reduced when recombinant collagen, cupola sachalinensis nanocapsules, supramolecular kapok or supramolecular carnosine is arbitrarily absent from the composition.
