EGCG, namely epigallocatechin gallate, with molecular formula of C22H18O11, is the main component of green tea polyphenols, and is a catechin monomer isolated from tea, with antibacterial, antiviral, antioxidant and other functions. The role of EGCG in cosmetics is summarized as follows: (1) anti-wrinkle and beauty effect; (2) Sunscreen and anti-spot effect; (3) Relieve toxic effects of heavy metals; (4) Antimicrobial and anti-inflammatory effects; (5) Promoting skin microcirculation; (6) It can be used as anti-oxidant, bacteriostatic, fresh-keeping and deodorant in the food industry
Tea polyphenols can significantly reduce the content of serum total cholesterol, triglyceride and low density lipoprotein cholesterol in hyperlipidemia, and have the effect of restoring and protecting vascular endothelial function. The hypolipidemic effect of tea polyphenols is also one of the main reasons why tea can make obese people lose weight without rebound.
Resveratrol was discovered in 1924 and was first isolated from the root of Veratrum grandiflorum by the Japanese in 1940. In 1976, Res (resveratrol) was also found in the leaves of grapes. It is an antitoxin secreted by plants in adverse circumstances or when they are attacked by pathogens. The synthesis of Res (resveratrol) is sharply increased in ultraviolet radiation, mechanical damage and fungal infection, so it is called phytoalexin. Res has been found in more than 700 plants, including 12 families, 31 genera and 72 species of plants, of which grape, polygonum cuspidatum, peanut and other human foods have a higher content.

Ghana seed extract generally refers to 5-hydroxytryptophan (5-HTP), which is an amino acid substance. It can be used as a precursor of 5-hydroxytryptamine (serotonin, 5-HT) in human body (and then as a precursor of melatonin). Some double-blind studies have shown that 5-HTP can increase the concentration of serotonin in the brain, improve depression, promote the formation of melatonin, improve sleep quality, and inhibit appetite, but these studies still have problems. Therefore, more research is still needed to confirm whether 5-HTP has these physiological effects.
Ghana seeds are rich in 5-hydroxytryptophan, which is the main natural source of 5-HTP at present.
5-HTP is classified as a pharmaceutical ingredient in some countries. In the United States, the United Kingdom and Canada, 5-HTP is sold as a dietary supplement (health product).
Rutin, also known as rutin and vitamin P, with the molecular formula of C27H30O16, is a natural flavonoid glycoside, belonging to the flavonol glycoside that widely exists in plants. The two glycosides are glucose and rhamnose. The appearance is light yellow or light green crystalline powder. It is soluble in pyridine, formyl and lye, slightly soluble in ethanol, acetone and ethyl acetate, and almost insoluble in chloroform, ether, benzene, carbon disulfide and petroleum ether. It has anti-inflammatory, antioxidant, anti-allergic, anti-viral and other effects.
Epimedium is a common Chinese traditional medicine with high medicinal value. It is a perennial herb with a plant height of 20-60 cm, a thick and short rhizome, lignified, dark brown, upright stem, angular, hairless, and usually without basal leaves. It is distributed in Jilin, Liaoning, Shandong, Jiangsu, Jiangxi, Hunan, and other places, and is born on the hillside, in the grass under the forest, and likes wet areas. Nourishing yin and yang, strengthening the body.
Epimedium is a traditional Chinese medicine tonic, which has the functions of tonifying the kidney, strengthening the bone, removing wind and dampness, and is used for impotence and ejaculation, flaccidity of the bone, rheumatism, pain, numbness and contracture, and menopausal hypertension. It can effectively inhibit staphylococcus and resist aging. Icariin is one of its effective ingredients, which can effectively improve the cardiovascular system, regulate the endocrine, and improve the endocrine. In addition, it is particularly noteworthy that Epimedium also has anticancer effect and is regarded as the most potential anticancer drug.
Coenzyme Q10, with the chemical name of 2 - [(all-E) 3,7,11,15,19,23,27,31,35,39-decamethyl-2,6,10,14,18,22,26,30,34,38-tetradecyl}-5,6-dimethoxy-3-methyl-p-benzoquinone, is one of the substances involved in the electron transfer chain and aerobic respiration in eukaryotic mitochondria. It is a yellow to orange crystalline powder, odorless and odorless, and easy to decompose when exposed to light.
α- Lipoic acid is light yellow powder crystal, almost tasteless. The solubility in water is small, about 1 g/L (20 ° C). It is soluble in 10% NaOH solution and aliphatic solvent. It is soluble in methanol, ethanol, chloroform and ether.
Lipoic acid α- Lipoic acid.
Since lipoic acid has a chiral center, it has two configurations: R and S.
Natural lipoic acid is a white crystal with only R configuration, and only R configuration lipoic acid can be covalently conjugated to lysine residues through amide bonds to play the role of coenzyme.
However, the synthetic lipoic acid is a mixture of equal proportion of R and S configurations, which is a light yellow powdery substance, and is extremely soluble in lipid solvents.
