Abstract

The invention discloses a preparation method of an eucommia extract product, comprising the following steps of: (1) extraction of a solvent, wherein the solvent is selected from water, methanol, ethanol, isopropanol, 1-butanol, glycol, 1,2-propylene glycol, 1,3-propylene glycol, 1,3-butylene glycol, acetone, ethyl acetate or their combination; (2) separation of an extract and residue so as to obtain the extract; (3) recovery of the optional solvent; and (4) optional dissolution or dilution. The eucommia extract product obtained by the method has antioxidation and UVA and UVB irradiation resistant effects, and can be used for ageing resistance of skin, especially light ageing resistance. The eucommia extract product can be used as a cosmetic additive or medicinal active component. The invention also discloses an application of the eucommia extract product in preparation of cosmetics or medicines for skin ageing resistance, especially for light ageing resistance.

Description

technical field [0001] The invention relates to the fields of natural medicinal chemistry and cosmetics, in particular to a Chinese herbal medicine Eucommia ulmoides used in cosmetics or medicines for anti-aging, preferably anti-photoaging. Background technique [0002] Studies have shown that both free radicals and ultraviolet rays are one of the factors of skin aging, and photoaging is mainly caused by medium-wave ultraviolet (UVB, 290-320nm) and long-wave ultraviolet (UVA, 320-400nm) in sunlight. Ultraviolet rays can significantly promote the aging of human skin. The risk of skin aging in high-exposure groups is twice that of low-exposure groups, and the aging occurs 10 years earlier. Long-term exposure to sunlight and ultraviolet rays can cause skin photoaging and cause serious cosmetic problems. Therefore, in recent years, it has attracted much attention from the industry. Anti-aging and anti-photoaging products have come out one after another. Related research is in fu...
