A kind of extraction process of total triterpenes of fern

Abstract

The present invention relates to a process for extracting total triterpenoids of Junima, which comprises the following steps: (1) Junima root is pulverized and sieved to obtain Junima root powder; (2) Junua root powder is extracted with ethanol solution to obtain an extract , the extract is filtered and concentrated under reduced pressure to obtain an extract; (3) add water to the extract to settle, leave it at room temperature after stirring, and then filter to obtain a sediment; (4) add absolute ethanol to the sediment to dissolve, To obtain a solution, add activated carbon to the solution to decolorize and remove impurities, recover ethanol, dry to constant weight under reduced pressure, and obtain a crude extract; (5) add ether to extract after dissolving the crude extract, stand at room temperature for stratification, repeat 3 Combined after ~5 times to obtain the extract; (6) add n-butanol to the extract for extraction, leave to stand at room temperature for stratification, take the n-butanol solution, repeat the extraction for 4 to 7 times, and combine to obtain the n-butanol solution, the n-butanol solution The butanol solution was dried under reduced pressure to constant weight to obtain the total triterpene extract of Bracken. The invention is simple, efficient and low in cost.

Description

technical field [0001] The invention relates to a process for extracting total triterpenes, in particular to a process for extracting total triterpenes of Bracken. Background technique [0002] The scientific name of Potentilla velvet is Potentilla velvet, a perennial herb belonging to the Rosaceae Potentilla genus. "Potentilla velvet" generally refers to the enlarged root tubers of Potentilla velvet, one of the more commonly used varieties of Tibetan medicine in my country. Root tubers have the effects of promoting body fluid and relieving cough, invigorating the spleen and stomach, astringent and hemostasis, etc. The triterpenoids contained in the root tubers are mainly triterpene acids and triterpene glycosides, which have pharmacological activities such as anti-inflammatory, anti-tumor, antibacterial, and immune regulation . At present, it has been applied in the field of medicine. However, the current extraction process of total triterpenes has cumbersome steps and do...

AI Technical Summary

Problems solved by technology

However, the current extraction process of total triterpenes is cumbersome and does not involve the removal of starch and sugar

Due to the low content of total triterpenes and high content of starch and sugar in Bracken, a large amount of starch and sugar will be extracted during the extraction process, which will cause great trouble to the purification of total triterpenes in the later stage.
