【Plant origin】Fallopia multiflora (Thunb.) Harald.

【Application】
Stilbene glycoside is identified as a plant antitoxin, which is produced by plants under the adverse conditions of fungal infection, ultraviolet radiation, mechanical damage and so on. It has been found that stilbene glycoside has a variety of physiological activities and medicinal value, and has shown its function in anti-aging, lipid-lowering, anti-oxidation and tumor inhibition.
Cosmetics application
Stilbene glycoside, the extract of Polygonum multiflorum Thunb, can significantly reduce the oxidative damage of superoxide radicals and has a strong anti-aging effect. At the same time, stilbene glycoside can effectively inhibit the decrease of SOD content in the body caused by ultraviolet rays, inhibit the increase of MDA content in the body caused by ultraviolet rays, protect the skin from physical damage caused by ultraviolet rays, improve the self-healing ability of the skin, so as to solve the problem of skin damage caused by ultraviolet radiation. Polygonum multiflorum has been widely used as cosmetics by oral or external use because of its proliferation effect on B-16 melanocytes, which can increase the secretion of melanin and make hair dark and bright. Anthraquinone derivatives of Polygonum multiflorum Thunb can inhibit bacteria such as Staphylococcus aureus, Streptococcus, diphtheria, anthrax, influenza virus, fungi and other pathogens to varying degrees.

【Test Method】 Determination of stilbene glycoside by HPLC-UV
【Storage Instructions】 Strictly protected from light, low temperature and dry environment

Note: if the temperature of stilbene glycoside is above 80 ℃, or it is unstable in the environment with strong acidity, the content and activity of stilbene glycoside should be reduced.
