The nicotinamide of the invention is prepared by oxidizing beta-picoline into nicotinic acid by air, reacting the nicotinic acid with ammonium hydroxide, and heating and dehydrating. Nicotinamide is a derivative of vitamin B3, is involved in the transport of melanin and accelerates the rate of melanosome movement in melanocytes, and has regulatory effects on calcium pump, the expression of the cell motor protein Dynein and melanosome movement, and the concentration of nicotinamide is an important regulatory factor. Niacinamide prevents the appearance of pigments on the skin surface, and in particular inhibits the migration of melanosomes to the skin surface. The topical niacinamide can improve dark yellow and dull skin due to aging. By insisting on using the nicotinamide stock solution, the skin texture is obviously improved, fine lines and wrinkles are obviously reduced, the skin becomes rich in elasticity, pigmentation and erythema are obviously reduced, dark yellow is obviously reduced, and the skin is rich in luster.
The glutathione of the present invention was purchased from japan pill company. Glutathione is small molecular peptide combined by glutamic acid, cysteine and glycine, has strong reducing effect, can reduce melanin in cells into light pigment, and can inhibit the formation of color spots.
The grape ferment-glutathione is obtained by compounding ferment fermented grape juice and glutathione. The grape ferment in the grape ferment-glutathione can activate dermal cells and promote the osmotic absorption of glutathione, thereby not only greatly solving the technical application problem of the glutathione, but also having the inhibition effect on tyrosinase and promoting metabolism.
The alpha-arbutin is obtained by fermenting natural active substances derived from green plants. Alpha-arbutin is white needle-shaped crystal or powder, which directly inhibits tyrosinase activity instead of inhibiting cell growth or tyrosinase gene expression to reduce melanin generation. The arbutin is a natural active substance derived from green plants, integrates the green plants, the safe and reliable and the efficient decoloration into a whole, can quickly permeate into the skin, can effectively inhibit the activity of tyrosinase in the skin and block the formation of melanin while not influencing the cell proliferation concentration, and accelerates the decomposition and excretion of the melanin by directly combining the arbutin with the tyrosinase, thereby reducing the skin pigmentation, removing color spots and freckles, and generating no toxic, irritant, sensitizing and other side effects on the melanocyte. The melanin inhibiting effect of alpha-arbutin is about 10 times stronger than that of beta-arbutin, and the whitening effect and safety of alpha-arbutin are higher than those of beta-arbutin.
The phenethyl resorcinol is prepared by carrying out Friedel-Crafts alkylation reaction on 1, 3-benzenediol and styrene to generate a phenethyl resorcinol crude product, and carrying out purification steps of cleaning, distilling, crystallizing and the like on the reaction crude product to obtain a final product. The phenethyl resorcinol is a novel efficient skin whitening agent, has good stability and safety, can improve uneven skin color and reduce skin coloring caused by ultraviolet irradiation on the skin. The phenethyl resorcinol is one of tyrosinase inhibitors with the highest activity, the activity of inhibiting the tyrosinase is 22 times that of kojic acid, the activity of inhibiting the B16V cell from synthesizing melanin is 210 times that of the kojic acid and 32 times that of arbutin, and the antioxidant activity of the phenethyl resorcinol is better than that of conventional antioxidants VE, VC and BHT.
The preparation of the vitamin C polypeptide comprises the following steps: the temperature is raised to 37 to 40 ℃ in a suitable stainless steel fermenter, the freshly harvested citrus fruit is first cut to very small pieces and the ascorbic acid synthesis reaction is then carried out with the ascorbic acid-conjugated citrus fruit and bioflavonoids until the reaction is stopped when no free ascorbic acid is detectable in the fermenter, which usually takes 4 to 6 hours. Then, filtering the remaining solid matter, washing the remaining slurry, wherein the washing liquid already contains the initial extraction component, then making the washing liquid into a concentrated solution by vacuumizing or under the protection of nitrogen, and finally, spraying the concentrated solution to free flowing white or cream powder to obtain the vitamin C polypeptide. The vitamin C polypeptide is a stable and non-discoloring vitamin C derivative containing a plurality of short peptides, can be conveniently added into cosmetics, can keep the activity of the vitamin C for a long time, and is not easy to be oxidized.
The invention relates to an extraction method of a fallen rhizogenesis leaf extract, which comprises the following steps: screening raw materials, crushing, sieving, fermenting, centrifuging, separating supernatant, and performing supercritical extraction to obtain the extract of the leaves of the rhizomes fallen to the ground. The extract of the fallen rhizomes leaf is also called raw Sichuan lotus and large-size yellow chicken claw in the fallen rhizomes of Taiwan area, and the effective components of the extract comprise: ferulic acid, syringic acid, caffeic acid, p-coumaric acid, friedelin, kaempferol, garcinia camomila flavin, quercetin, campesterol, stigmasterol, taraxasterol, mucinol, kaempferol-3-rhamnoside. The effective components in the extract of the leaves of the rhizomes fallen onto the ground can effectively prevent the skin from being oxidized.

1. Analysis of antioxidant component of extract of leaves of Farfarae
In this example, the antioxidant component of the extract of the leaves of the rhizomes of fallen flowers was analyzed, and the analysis results are shown in table 1.
TABLE 1 Main antioxidant ingredient list of extract of Salvia miltiorrhiza leaves
Figure BDA0002685410950000111
Polyphenols: phenolic compounds are the largest group of phytochemicals and are believed to have anti-radical and anti-aging effects.
Flavonoid: flavonoids, the largest group of polyphenols, are believed to have a strong antioxidant capacity, which is two to three times that of red wine or green tea, and can capture free radicals and chelate magnesium-contacting metal ions required for peroxidation, especially for some dark chocolates containing the flavonoid epicatechin.
Anthocyanins: anthocyanins, also known as anthocyanidins, are water-soluble natural pigments, which are one of the bioflavonoids, and are believed to have very strong antioxidant and anti-inflammatory properties, and are capable of resisting free radicals and delaying aging.
Antioxidant principle of the extract of the leaves of the rhizomes fallen to the ground: the lipid will generate free radicals during the oxidation process, and the free radicals will combine with the oil to generate more free radicals, so as to further scavenge the free radicals in the environment by the antioxidant, and stop the continuous reaction of peroxidation, i.e. scavenge the free radicals to provide the antioxidant effect.
2. Method for measuring oxidation resistance
DPPH radical scavenging capacity: DPPH is a violet-black radical solution having the highest absorbance at a wavelength of 517nm, and after reacting with hydrogen ions or electrons, its color becomes pale yellow, so that the absorbance becomes lower and lower, and thus is often used in the measurement of antioxidant ability.
ABTS+The determination and analysis method comprises the following steps: ABTS in proper location, also known as total antioxidant capacity determinationABTS oxidized into green under the action of oxidant+ABTS in the presence of antioxidants+Can be suppressed. Ability to chelate ferrous ions, Fe2+(ferrous ion) is the most influential pro-oxidant, which promotes lipid oxidation, to Fe2+The chelating ability of (ferrous ions) is often closely related to its resistance to oxidation.
