| Zusammenfassung: | The invention relates to a kind of effective constituent separation method in vegetation extract, especially the method of separating lycorine from vegetation extract containing amaryllidaceae alkaloid. The industrial art is as follows: make vegetation extract containing amaryllidaceae alkaloid have pretreatment; adsorb and elute with cation exchange resin; track and detect the elution flowing composition; make the flowing composition in lycorine have concentration and enrichment; after get virgin product of lycorine free alkali, make it have recrystallization with organic solvent; finally, the lycorine free alkali crystallization with about 99% purity can be acquired. |
