摘要：Chemical identification of japanese cannabis was described. Hexane-extract of cannabis was fractionated by column chromatography to give a fraction containing the specific components by eluting with benzene. Since the ethanol-soluble portion of this fraction showed characteristic peaks at 277 and 284 mμ in U.V. absorption spectra and exhibited the typical color reactions, it was found to furnish more distinct results than whole extract for purpose of identification of cannabis.
