Abstract

The invention relates to a method for preparing a cosmetic extract, which belongs to the field of natural extract preparation. The method comprises the following steps: 1) crushing the dried bletilla striata root, wetting it with citric acid solution, spreading the moistened bletilla striata root on the silk screen, erecting the silk screen in an airtight box, and laying a layer of fresh cloves on the bottom of the screen Flowers, the temperature in the box is heated to 40-60°C and kept for 1-3 days; 2) Take out the root of Bletilla striata, soak it in water at 50-65°C for 1-2 hours, add cellulase and pectinase in the water; then heat the water After reaching 70-80°C, perform ultrasonic treatment for 10-30 minutes; finally carry out distillation and extraction at 100-110°C for 3-5 hours, collect the oily substance in the distillation condensate, and obtain a crude extract; After the resin is purified, it is allowed to stand still to take the oily substance to obtain the product. The method can effectively extract the volatile oil components in the roots of the bletilla striata and the flowers of the lilac flowers, so as to prepare the natural extracts with the functions of beautifying and skin care.

Description

technical field [0001] The invention relates to a preparation method of a plant extract, in particular to a preparation method of a cosmetic extract.
