Abstract
AIM:To study the active constituents of the stems or root of Fissistigma oldhamii.METHOD:Compounds were isolated by means of column chromatography,and the structures were identified on the basis of MS and NMR spectral analysis.RESULT:Sixteen compounds were isolated and identified as:calycinine(1),N-methyl-2,3,6-trimethoxy morphinandien-7-one(2),aristololactam AⅢa(3),xylopine(4),crebanine(5),isolaureline(6),asimilobine(7),duguevanine(8),corytuberine(9),aristololactam AⅡ(10),isoboldine(11),goniothalactam(12),glaucine(13),(-)-epicatechin(14),aristololactam BⅡ(15),7′-(3′,4′-dihydroxyphenyl)-N-{(4-methoxyphenyl)ethyl}propenamide(16).CONCLUSION:Compounds 3,5,12,15 were isolated from this plant for the first time; compounds 6,7,8,9,11,13,14,16 were isolated from Fissistigma for the first time.
