Abstract
Four hitherto unknown prenylated isoflavonoids, named derrisisoflavones H-K (1-4) and one new isoflavan, namely 6-hydroxyisosativan (5), were isolated from the ethanol extract of Derris robusta. Their structures were elucidated on the basis of extensive spectroscopic studies. To our knowledge, derrisisoflavones J (3) and K (4) are the first examples of hydroxyethylated isoflavonoid.
摘要
从毛鱼藤（Derris robusta）的乙醇提取物中分离出四种此前未知的异戊烯基化异黄酮，命名为鱼藤异黄酮H-K（1-4），以及一种新的异黄烷，即6-羟基异萨替烷（5）。通过广泛的光谱研究阐明了它们的结构。据我们所知，鱼藤异黄酮J（3）和K（4）是羟乙基化异黄酮的首个实例。
