erocarpan and a new santal analogue were isolated from the heartwood of P. soyauxii. These are accompanied by several known pterocarpans, isoflavans, isoflavones and trans-pterostilbene. From the heartwood of P. marsupium were obtained 8-C-β- d -glucopyranosyl-3,7,4′-trihydroxy- and -3,7,3′,4′-tetrahydroxyflavone, representative of the first 5-deoxy C-C-coupled flavonol glucosides, and the rare 3′-C-β-
摘要 从P. soyauxii 的心材中分离到了两种新型翼果木,8-羟基-3,9-二甲氧基-和3,8-二羟基-9-甲氧基翼果木以及一种新的檀香类似物。这些伴随着几种已知的紫檀、异黄烷、异黄酮和反式紫檀芪。从 P. marsupium 的心材中获得了 8-C-β-d-吡喃葡萄糖基-3,7,4'-三羟基-和 -3,7,3',4'-四羟基黄酮,代表第一个 5-脱氧 CC -偶联的黄酮醇糖苷,和罕见的 3'-C-β-d-吡喃葡萄糖基-α-羟基二氢查尔酮,它们的结构是通过高分辨率 NMR 技术确定的。
