In addition to the known Compounds senegalensin, lupinifolin, erythrisenegalone, and auriculatin, two new isoflavones named erysenegalensein H and erysenegalensein I were isolated from the dichloromethane extract of the stem bark of ERYTHRINA SENEGALENSIS DC. On the basis of spectroscopic methods their structures were elucidated as 5,2',4'-trihydroxy-8-(gamma,gamma-dimethylallyl)-2''-hydroxyisopro
除了已知的塞内加仑素,羽扇豆酚,赤藓烯酮和奥耳菌素化合物外,还从ERYTHRINA SENEGALENSIS DC茎皮的二氯甲烷提取物中分离出了两种新的异黄酮,分别名为erysenegalensein H和erysenegalenseinI。根据光谱方法,其结构被阐明为5,2',4'-三羟基-8-(γ,γ-二甲基烯丙基)-2''-羟基异丙基二氢呋喃[4'',5'':6,7]-异黄酮和5,2',4'-三羟基-8-(γ,γ-二甲基烯丙基)-3''-羟基-2'',2''-二甲基二氢吡喃[5'',6'':6,7] -异黄酮。
