Abstract

The invention discloses a method for extracting and separating the total alkaloids of shiny leaf pricklyash root; the method comprises the following steps: the shiny leaf pricklyash root is crushed, extracted for 1 time to 5 times with acid water-alcohol as a solvent and filtered; the filtrates are combined and decompressed, have the solution removed so that no alcoholic odor exists and are set stewing and delaminated; the supernatant fluid is fetched, and the sediment is repeatedly dissolved by acid water and filtered to obtain a filtrate which is combined with the supernatant fluid, adsorbed by a macroporous resin column and washed by an organic solvent, and then the solvent is recovered to obtain a crude alkaloid product. The method of the invention increases the extraction ratio to more than 93 percent by adding acid for extraction, and macroporous resin is used for separating alkaloids, simple and easy operated, achieving a yield rate about 93 percent.

Description

technical field

[0001] The invention relates to a method for extracting and separating traditional Chinese medicinal materials, in particular to a method for extracting and separating total alkaloids of liangmianzhen. Background technique

[0002] The existing method for extracting the total alkaloids of LMZ is reflux extraction with methanol, 60% ethanol or 95% ethanol. Methanol is highly toxic and is generally used for continuous reflux extraction, which is not suitable for industrial production; 95% ethanol reflux extraction is a method used by early researchers to study chemical components and their pharmacological activities, and the extraction rate of total alkaloids is relatively low. It is not suitable for industrial production; take a Ding-shaped double-sided needle medicinal material about 1 cubic centimeter in size and reflux twice with 60% ethanol, the first 9 times the amount of reflux for 2 hours, the second time 7 times the amount of reflux for 1.5 hours, the ...
