Objective:
To establish a method for isolating and identifying koumine.
Methods:
Koumine was first extracted from Gelsemium alkaloids by using chloroform, which was further separated and purified by column chromatograph, and identified by thin-layer chromatography.
Results And Conclusion:
Koumine crystals were isolated and purified from Gelsemium alkaloids effectively.
