Embodiment 1

[0013] Take 200 mg of the methanol extract of Corydalis Corydalis made from vinegar and dissolve it in 10 mL of 5% methanol water to obtain a 20 mg / mL extract solution. 10g of C18 / WCX filler (particle size 40μm) was filled in an open SPE column tube, first activated with 30mL of methanol, then equilibrated with 30mL of water, and set aside. Pour 10mL of sample into the empty tube above the SPE column, and load the sample onto the SPE column at a speed of about 2mL / min. After the sample is loaded, rinse it with 60mL of 10% methanol water to remove the more polar impurities; then Use 60mL of 80% methanol to elute the tertiary amine alkaloid in two tubes; then wash with pure methanol until the eluate is colorless, and remove other non-alkaloid components with weak polarity; finally, use 1% formic acid The quaternary ammonium alkaloids were eluted with methanol until the eluent was colorless (about 20 mL). After elution, the SPE column returns to white, and after equilibrating wi...

Abstract

The invention provides a method for classifying and preparing tertiary amine alkaloid and quaternary ammonium alkaloid from corydalis extract. The method comprises the following steps of eluting different solvents according to a like component preparation method by adopting a C18/WCX (Weak cation exchange) type separating material with the combination of the hydrophobic effect and a weak cation exchange function, removing impurities, and enriching tertiary amine alkaloid and quaternary ammonium alkaloid, which are completely different in functional activity, contained in the corydalis extract respectively, wherein the total alkali contents in two like components can reach more than 65% and more than 90% respectively through HPLC (High Performance Liquid Chromatography) analysis. The preparation method has simple process, and has high efficiency and high recovery rate, the used separating material can be used repeatedly, the production cost is low, and the method can provide a good technical scheme for developing safe, efficient and controllable Chinese herbal preparations with alkaloids components.

Description

Technical field: [0001] The invention belongs to the technical field of separation and purification of alkaloids, and in particular relates to a method for preparing traditional Chinese medicine alkaloid components. Background technique: [0002] Corydalis yanhusuo (Yuanhu) is the tuber of Corydalis yanhusuo W.T.Wang, a plant of the poppy family. It is warm in nature and bitter in taste, can promote blood circulation and disperse blood stasis, benefit qi and relieve pain. It is one of the famous "eight flavors of Zhejiang" and has high medicinal value. Modern medicinal chemistry and pharmacology experiments have shown that the main active ingredients in Corydalis are two types of alkaloids, tertiary amine and quaternary ammonium, of which the content of tertiary amine base is about 0.65%, and the content of quaternary ammonium base is about 0.3% (He Kai, Gao Jianli , Zhao Guangshu. Corydalis chemical constituents, pharmacological effects and quality control research progress...
