Embodiment 1

[0042] Add 150 g of flaky Bletilla striata into pure water 10 times the weight of the raw material, extract at 70°C for 3 hours, and after the extraction is completed, filter and remove the residue while it is hot to obtain the coarse filtrate of Bletilla striata, adjust the temperature of the coarse filtrate to 60°C, and add 5wt% acid protease , keep warm for 1 hour for enzymolysis, when the enzymolysis is over, raise the temperature to 80°C, add 5wt% high-temperature amylase, and keep warm for 1 hour for enzymolysis. Enzymolysis ends, in enzymolysis solution, add 15wt% white diatomaceous earth filter aid, obtain fine filtrate, add the ion exchange resin (preferably 717 resin) of raw material weight 15wt% in fine filtrate, stir and adsorb for 1 hour, adsorption ends After filtration, HCl was added to the filtrate to adjust the pH value to 6. With the filtrate after adjusting the pH, adjust the temperature to 70°C, add raw material weight 8wt% activated carbon to the feed liqu...

Embodiment 2

[0044] Add 150 g of flaky Bletilla striata into pure water 15 times the weight of the raw material, and extract at 90°C for 1 hour. After the extraction is completed, filter and remove the slag while it is hot to obtain the coarse filtrate of Bletilla striata, adjust the temperature of the coarse filtrate to 40°C, and add 0.05wt% of Acid protease, keep warm for 6 hours for enzymolysis, after the end of the enzymolysis, raise the temperature to 80°C, add 0.05wt% high-temperature amylase, keep warm for 6 hours for enzymolysis. Enzymolysis ends, in enzymolysis solution, add 4wt% white diatomite to aid filter, obtain fine filtrate, add the ion exchange resin (preferably 717 resin) of raw material weight 4wt% in fine filtrate, stir and adsorb for 6 hours, adsorption ends After filtration, HCl was added to the filtrate, and the pH of the filtrate was adjusted to 6. With the filtrate after adjusting the pH, adjust the temperature to 50°C, add raw material weight 2wt% activated carbon...

Embodiment 3

[0046]Add 150 g of flaky Bletilla striata into pure water 12 times the weight of the raw material, and extract at 80°C for 2 hours. After the extraction is completed, filter and remove the slag while it is hot to obtain the coarse filtrate of Bletilla striata, adjust the temperature of the coarse filtrate to 50°C, and add 2.5wt% of Acid protease, keep warm for 3 hours for enzymolysis, after the end of the enzymolysis, raise the temperature to 90°C, add 2.5wt% high-temperature amylase, keep warm for 3 hours for enzymolysis. Enzymolysis ends, in enzymolysis solution, add 10wt% white diatomaceous earth to aid filter, obtain fine filtrate, add the ion exchange resin (preferably 717 resin) of raw material weight 10wt% in fine filtrate, stir and adsorb for 3 hours, adsorption ends After filtering, add HCl to the filtrate to adjust the pH value of the filtrate to 6. Adjust the temperature of the filtrate after pH adjustment to 60°C, add 6wt% activated carbon by weight of raw material...

Abstract

The invention discloses a preparation method of a bletilla striata extract with repairing and whitening effects and the bletilla striata extract. According to the preparation method of the bletilla striata extract, technologies of enzymolysis, resin adsorption, decoloration and the like are utilized, unstable components in bletilla striata can be removed, meanwhile, the effective component bletilla striata polysaccharide is reserved, a large amount of solvents such as ethyl alcohol, acetone and diethyl ether are not used in the preparation process, the processing cost is reduced, and meanwhile the extraction yield is high; tests prove that the bletilla striata extract prepared by the invention has the effects of whitening and repairing, and can be applied to cosmetics; and the prepared bletilla striata extract is liquid and is relatively stable.

Description

technical field [0001] The invention relates to the technical field of plant extracts, in particular to a preparation method of bletilla striata extract with repairing and whitening effects and the bletilla striata extract. Background technique [0002] Bletilla striata is a precious traditional Chinese medicine, which has the functions of reducing swelling and promoting muscle growth, astringent and hemostasis. Modern studies have shown that Bletilla striata has anti-tumor, immune-regulating, and wound-healing effects. [0003] Bletilla striata contains starches, macromolecular proteins, and polyphenols, which easily cause problems such as precipitation or discoloration in the solution. Therefore, it needs to be removed during processing to meet the requirements of cosmetics for product stability. [0004] At present, the research and extraction mainly focus on polysaccharides. For the preparation and purification of Bletilla striata polysaccharides, technical means such a...
