amino-substituted isoflavones and one with an oxazole ring were isolated from the root bark of Piscidia erythrina . Their structures were established as 4′-amino-5,7,3′-trihydroxy-5′-methoxy-2′,6′-di-(3,3-dimethylallyl)isoflavone, 4′-amino-5,7,3′-trihydroxy-5′-methoxy-8,2′-di-(3,3-dimethylallyl)isoflavone and 7-hydroxy-5′-methoxy-2′-(3,3-dimethylallyl)-oxazolo-[4‴,5‴:4′,3′]isoflavone by spectroscopic
摘要 从赤藓霉的根皮中分离得到2种氨基取代的异黄酮和1种带有恶唑环的异黄酮。它们的结构被确定为 4'-氨基-5,7,3'-三羟基-5'-甲氧基-2',6'-二-(3,3-二甲基烯丙基)异黄酮, 4'-氨基-5,7, 3'-三羟基-5'-甲氧基-8,2'-二-(3,3-二甲基烯丙基)异黄酮和7-羟基-5'-甲氧基-2'-(3,3-二甲基烯丙基)-恶唑并-[4 ‴,5‴:4',3']异黄酮光谱法和化学法。这些异黄酮中的第一个被化学转化为一种化合物,该化合物也可以从相应的 4'-羟基异黄酮,红花红素中获得。
