new prenyl(=3-methyl-2-butenyl)isoflavones, euchrenones b6-b9, were isolated from stems of Euchresta horsfieldii from Thailand in addition to four known isoflavones (warangalone, osajin, 6,8-di(3-methyl-2-butenyl)genistein and 8-O-methylretusin) and two pterocarpans (maackiain and sophoracarpan B). 1H NMR spectral properties of regio-isomers, such as warangalone and osajin, are also discussed.
摘要 除了四种已知的异黄酮(warangalone、osajin、6,8-di(3-methyl -2-丁烯基)染料木黄酮和 8-O-甲基维甲素)和两种翼果(maackiain 和 sophoracarpan B)。还讨论了区域异构体(例如 warangalone 和 osajin)的 1 H NMR 光谱特性。
