실험 절차
About 0.25 g. of leurosine sulfate were converted to the free base by dissolving the salt in water and making the resulting solution alkaline. The free base was insoluble in the aqueous alkaline layer and was extracted with chloroform. Evaporation of the chloroform yielded leurosine free base as a residue.
