Problems solved by technology

[0003] At present, there are many reports in the literature on the method of extracting the total saponins of Rhizoma Rhizoma Pedis, most of which adopt ethanol reflux extraction and then cooperate with macroporous resin as the separation and preparation method of the adsorbent, but the extraction efficiency of total saponins of Rhizoma Rhizome is low, and the process is not good. Stablize

Abstract

The invention discloses a process for fermenting and extracting picroside from rhizoma picrorhizae. The process comprises the following steps: crushing a rhizoma picrorhizae raw material; preparation of an enzyme preparation: dispersing cellulase, hemicellulase, protease, amylase and glycosidase in water to obtain the enzyme preparation; preparing a fermentation product: adding sucrose ester and ammonium oxalate into the enzyme preparation, uniformly mixing, adding the crushed rhizoma picrorhizae, and inactivating at high temperature; extracting a rhizoma picrorhizae extract: extracting a fermentation product by using an extraction solvent according to a percolation method, concentrating the extracted solution under reduced pressure, diluting, adsorbing by using purified macroporous adsorption resin, eluting, collecting eluent, concentrating under reduced pressure, drying and crushing; and obtaining picroside: dissolving the rhizoma picrorhizae extract with absolute ethyl alcohol, filtering, mixing filtrate into chromatographic silica gel for sample mixing, drying, eluting, and crushing to obtain the picroside. The process for extracting picroside from picrorhiza rhizome through fermentation is simple in preparation, high in picroside content, safe, easy to operate and low in cost.

Description

technical field [0001] The invention relates to the technical field of berberine extraction, in particular to a process for fermenting and extracting berberine from berberine. Background technique [0002] Huhuanglian is a perennial herb of Scrophulariaceae. It has a similar name to Coptis chinensis. Both of them are bitter cold, clearing away heat and dampness. They are good at removing dampness and heat in the stomach and intestines. At present, it has been found that the chemical components of Coptis chinensis mainly include iridoids, cucurbitacins, phenylethyl alcohol glycosides and phenolic glycosides, and also contain very small amounts of mannitol, berberine alcohol, berberine sterol, vanilla ethyl ketone and Aromatic acid, etc., iridoid glycosides (total saponins of Huhuanglian) as the main active ingredients have various pharmacological activities such as anti-hepatitis B virus, liver protection, and enzyme reduction. The effects of liver, gallbladder, and insectic...
