Processing method of common bletilla tuber crude medicine

Abstract

The invention discloses a processing method of a common bletilla tuber crude medicine. The processing method of the common bletilla tuber crude medicine comprises the following steps: harvesting common bletilla tubers; washing the harvested common bletilla tubers so as to have soil on the surface of the common bletilla tubers rinsed off; putting the washed common bletilla tubers into warm water, and adding baijiu of which the ethanol concentration is 52%vol at a warm water to ethanol volume-ratio of 1000 to 3 so as to be subjected to soaking; taking the soaked common bletilla tubers out, air-drying the common bletilla tubers, and removing fibrous roots and peel; slicing the dried common bletilla tubers, namely curing the common bletilla tubers without the fibrous roots and the peel, air-cooling the common bletilla tubers and carrying out slicing so as to obtain common bletilla tuber slices; crushing the common bletilla tuber slices, namely drying the common bletilla tuber slices by using hot air, and carrying out particle pulverization so as to obtain particle-pulverized common bletilla tuber powder; carrying out separation and extraction, namely adding purified water into the particle-pulverized common bletilla tuber powder, carrying out uniform stirring, carrying out ultrasonic treatment for 30 minutes, carrying out heating and extracting, separating residues from liquid after completion of the extraction, and repeatability extracting the residues for more than 3 times so as to obtain extracted liquid materials; concentrating the extract, namely mixing the liquid materials from the various times of extractions so as to obtain a mixture, concentrating the mixture so as to obtain a concentrate, hydrolyzing the concentrate so as to obtain a hydrolysate, performing decolorizing treatment on the hydrolysate, and carrying out centrifugal separation so as to obtain a liquid supernatant; and then, carrying out vacuum freeze-drying, namely freezing the liquid supernatant so as to have moisture sublimated, and carrying out high-pressure sterilization so as to obtain common bletilla tuber powder. The processing method of the common bletilla tuber crude medicine is capable of preserving gum components in common bletilla tubers to the maximum extent; and thus, the prepared common bletilla tuber crude medicine is high in biological activity and high in purity.

Description

technical field [0001] The invention relates to the technical field of processing bletilla striata medicinal materials, in particular to a method for processing bletilla striata medicinal materials. Background technique [0002] Bletilla striata is a traditional Chinese medicine. According to " Pharmacopoeia " record: Bletilla striata converges and stops bleeding, reduces swelling and promotes granulation. For hemoptysis and hematemesis, traumatic bleeding, ulcer swelling, skin rupture; tuberculosis hemoptysis, ulcer bleeding. Modern medical research shows that Bletilla striata has antibacterial, antitumor, and antiulcer effects [2-6]. In addition to its irreplaceable role in the field of medicine, it is also widely used in the food industry, tobacco industry, and chemical industry. It has a wide range of uses. Because of its irreplaceable miraculous curative effect and wide range of uses, the market demand for Bletilla striata is increasing, and the market mainly relies ...

AI Technical Summary

Problems solved by technology

During the processing of bletilla striata in the place of origin, according to their own processing habits and sales needs, some farmers directly dry or sun-dry some bletilla striata, some steam or boil them and dry them at will, some peel off the skin, some do not peel the skin, etc., resulting in the bletilla striata The quality is uneven, which affects the medicinal effect of bletilla striata
