Three prenylated flavonoid derivatives; 5,7,4'-trihydroxy-8-(3"'-methylbut-2"'-enyl)-6-(2"-hydroxy-3"-methylbut-3"enyl) isoflavone (isoerysenegalensein E), 5,7,2'-trihydroxy-4'-methoxy-5'-(3"-methylbut-2"-enyl) isoflavanone (lysisteisoflavanone), 5, 4'-dihydroxy-6-(3"'-methylbut-2"'-enyl)-2"-hydroxyisopropyl dihydrofurano [4",5":8,7] isoflavone (isosenegalensin), together with the four known flavonoids abyssinone V-4'-methylether, alpinumisoflavone, wighteone and burttinone were isolated from the stem bark of Erythrina lysistemon Hutch. (Leguminosae). Structures were elucidated by spectroscopic methods.
从刺桐属植物刺桐（豆科）的茎皮中分离出三种异戊烯基黄酮衍生物：5,7,4'-三羟基-8-(3"'-甲基丁-2"'-烯基)-6-(2"-羟基-3"-甲基丁-3"烯基)异黄酮（异刺桐塞因E）、5,7,2'-三羟基-4'-甲氧基-5'-(3"-甲基丁-2"-烯基)异黄烷酮（刺桐异黄烷酮）、5,4'-二羟基-6-(3"'-甲基丁-2"'-烯基)-2"-羟基异丙基二氢呋喃并[4",5":8,7]异黄酮（异刺桐素），以及四种已知黄酮阿比西酮V - 4'-甲基醚、高山异黄酮、维特酮和布廷酮。通过光谱方法阐明了其结构。
