Abstract

The invention discloses a preparation method of a Gynostemma pentaphylla extract product. The method comprises the following steps: 1, extracting a raw material with 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 a combination thereof; 2, separating the obtained extract liquid and residues to obtain the extract liquid; 3, optionally recovering the solvent; and 4, optionally dissolving or diluting. The invention also discloses the Gynostemma pentaphylla extract obtained through using the method. The invention further discloses an application of the Gynostemma pentaphylla extract in the preparation of skin light ageing resistance cosmetics or medicines.

Description

technical field [0001] The invention relates to the fields of natural medicine chemistry and cosmetics, in particular to a Chinese herbal medicine Gynostemma pentaphyllum for anti-photoaging in cosmetics or medicines. 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 full swing, but natural C...
