Embodiment 1

[0017] Example 1 Extraction process of Gorcia root dried medicinal material

[0018] The genus root extract mentioned in the present invention is extracted from the root or root bark of the medicinal plant Caragana japonica through multiple reflux extractions with organic solvents. The solvent-extracted components are further purified by chromatography or fractional distillation, and the product is isolated. The crushed particle size of the gorse root is 100um-5000um; 30-90% ethanol aqueous solution is used for heating and reflux extraction; the ratio of gorse root powder to solvent is 1:10; the extraction temperature is kept between 20-90°C; the extraction The time is between 8-24 hours; the ethanol extract is decolorized with 1-40% activated carbon, concentrated, dried, and set aside. process such as figure 1 shown.

[0019] The sample liquid is further concentrated and dried to obtain the ethanol extract of Gorcia root. The appearance of the product is brown powder (i...

Abstract

The invention relates to cosmetics industry, in particular to a method for extracting caragana sinica rehd and application of caragana sinica rehd extract to cosmetics. The method comprises the following steps of: mechanically grinding and crushing root or velamen of medicinal plant caragana sinica into powder; refluxing and extracting the powder by using an organic solvent for multiple times; and purifying components which are obtained through solvent extraction by chromatography or a fractionation method further, and separating to obtain the caragana sinica rehd extract. The extract has the activity of inhibiting trypsin, so the extract has the effects of preventing skin wrinkling and can be used as a natural plant additive in daily cosmetics.

Description

technical field [0001] The invention relates to the cosmetics industry, in particular to an extraction method of gorse root and the application of the extract in cosmetics. Background technique [0002] Skin is an important part of maintaining human life and health. It is in direct contact with the outside world and is the first barrier of the body. It is extremely vulnerable to damage caused by environmental factors. In addition to aging factors caused by physiological factors such as age and hormone levels, stress response, pollution, sunlight and ultraviolet radiation are all important causes of skin wrinkles. [0003] Skin aging is mainly manifested in two aspects. One is that collagen is degraded and lost under the action of various proteases, and the skin loses elasticity to form wrinkles; stains. During the aging process of the skin, trypsin and matrix metalloproteinase not only participate in the degradation of matrix protein and collagen in the skin structure, but...
