Two new cytotoxic isoflavans, (3S)-7-hydroxy-2',3',4',5', 8-pentamethoxyisoflavan (1) and (3S)-3',7-dihydroxy-2',4',5', 8-tetramethoxyisoflavan (2), were isolated from the bark and trunks of Eysenhardtia polystachya (Leguminosae), together with the known constituents stigmasterol, isoduartin, cuneatin, 7-hydroxy-2',4', 5'-trimethoxyisoflavone, and 3,4-dimethoxy-8, 9-(methylenedioxy)pterocarpan. The
两种新的细胞毒性异黄烷醇(3S)-7-羟基-2',3',4',5',8-五甲氧基异黄烷(1)和(3S)-3',7-二羟基-2',4',5从八叶参(Eysenhardtia polystachya(Leguminosae)的树皮和树干)中分离出8'-四甲氧基异黄酮(2),以及已知的成分豆固醇,异杜瓦汀,库尼丁,7-羟基-2',4',5'-三甲氧基异黄酮和3,4-二甲氧基-8,9-(亚甲二氧基)罗丹果胶。根据光谱学方法阐明了1和2的结构。对其中某些化合物的抗微生物,细胞毒性和杀虫潜力进行了评估。异黄烷1、2和异杜artin(2',7-二羟基-3',4',8-三甲氧基异黄烷)对KB细胞系表现出中等的细胞毒活性。
