Embodiment 1

[0056] Take 50g of paeonol, dissolve it with 100mL of absolute ethanol, add dropwise to 4L of 5wt% bletilla striata polysaccharide aqueous solution at a constant temperature of 40°C, stir at 300rpm for 5h, cool to room temperature, and freeze-dry to obtain a white powder. The solid was washed with 2 times the volume of petroleum ether, the supernatant was discarded by centrifugation, and the precipitate was freeze-dried to obtain 181.8 g of powder, which was clathrate. The yield was 72.7%, and the encapsulation rate was 30.2%.

Embodiment 2

[0058] Take 50g of paeonol, dissolve it in 80mL of anhydrous methanol, add dropwise to 3L of 10wt% Achnatherum polysaccharide aqueous solution at a constant temperature of 55°C, stir at 600rpm for 3h, cool to room temperature, spray dry, and control the temperature of the air outlet at 65°C to 70°C. °C, a white powder was obtained, which was washed with 3 times the volume of acetone of the white powder, the supernatant was discarded by centrifugation, and the precipitate was freeze-dried to obtain 267.1 g of the powder, which is the clathrate. The yield was 76.3%, and the encapsulation rate was 32.4%.

[0059] Identification of paeonol and its inclusion complex differential analyzer:

[0060] Four samples of paeonol, bletilla striata polysaccharide, physical mixture, and clathrate were taken for differential scanning thermal analysis on a differential thermal analyzer (CDR-4P type): weigh about 5.0 mg of sample, the range is ±50 μV, and the temperature rises The range is 40°C...

Abstract

The invention pertains to the field of cosmetics, and discloses a paeonol-bletilla striata polysaccharide inclusion compound, a preparation process and the application thereof. Two components of the inclusion compound have the weight percentage as follows: 70%-95% of the bletilla striata polysaccharide and 5%-30% of the paeonol. The inclusion compound can be taken as a cosmetic additive, and has obvious effects of removing spot and whitening skin, delaying skin senility, moistening skin, resisting bacteria and relieving inflammation, and the like, after being added to relevant cosmetic products.

Description

technical field [0001] The invention belongs to the field of cosmetics, and relates to paeonol bletilla striata polysaccharide inclusion compound and its preparation process and application. Background technique [0002] The application of natural plants in beauty and skin care has a long history. It appeared as early as the Qin and Han Dynasties, and became very popular in the Tang Dynasty. Organic acids, oils, alkaloids, essential oils, mucus, proteins, amino acids, vitamins, minerals, trace elements, plant hormones and other substances contained in plants can all have different effects and influences on human skin. For example, tannins have the effect of astringent skin, saponins have the effect of decontamination and descaling, acids have anti-inflammatory and bactericidal effects, mucopolysaccharides have moisturizing effects, amino acids can nourish the skin and reduce wrinkles, and protein is also good for enhancing skin elasticity. With the advancement of science an...
