Physical and chemical identification:
Take the product powder 50g (40 mesh), use methanol in the Sabim extractor reflux 3b, recovery of methanol, the residual extract is distilled back to 100ml dissolved, extracted with n-butanol 3 times, 50ml each time, vacuum recovery n-butanol The extracts were washed 3 times with 5 ml of diethyl ether, the residue was digested with indole, passed through an activated charcoal column chromatography, and eluted with acetone. The elution solution was added with Godin's reagent (1% vanillin in ethanol and 3% high). An aqueous solution of chloric acid was mixed in equal amounts immediately before use to give a purple color.
