摘要:
利用Sephadex LH-20及硅胶等柱色谱技术从药用民族植物角蒿(Incarvillea dissectifoliola Q.S.Zhao)的根茎中分离得到了11个环己乙醇类化合物.经理化数据对照和波谱分析,确定它们的结构分别为rengyolone(1), (3aS, 6R)-2,3,3a,6,7,7a-hexahydrobenzofuran-3a,6-diol (2),(3aR)-hexahydro-3a-hydroxybenzofuran-6(2H)-one(3),(3aR,6R)-octahydrobenzofuran-3a,6-diol (4),(3aR,6S)-octahydrobenzofuran-3a,6-diol (5),4-hydroxy-4- (2-hydroxyethyl) cyclohexanone (6),(3aS,4S)-hexahydro-3a,4-dihydroxybenzofuran-6(2H)-one (7),(3aR,4S)-hexahydro-3a,4-dihydroxy benzofuran-6(2H)-one (8),rengyol (9),isorengyol (10)和rengyoside B (11).这11个化合物均为首次从角蒿中分离得到.化合物4,5,6,7,8,9,10的细胞毒活性未见报道,对它们的细胞毒活性进行了测定,结果表明它们对HL-60细胞株的IC50分别为102,44.7,24.6,98.0,47.8,25.3,92.3和47.2 μmol/L.
