Abstract The structures of two neoflavonoids, isolated from a benzene extract of Coutarea hexandra have been established as 3′-hydroxy-5,7,8,4′-tetramethoxy-4-phenylcoumarin and 8,3′-dihydroxy-5,7,4′-trimethoxy-4-phenyl-coumarin. The substitution pattern of 8,3′,4′-trihydroxy-5,7-dimethoxy-4-phenylcoumarin, also isolated, was also confirmed by chemical reactions.
摘要 从 Coutarea hexandra 苯提取物中分离的两种新黄酮类化合物的结构已确定为 3'-羟基-5,7,8,4'-四甲氧基-4-苯基香豆素和 8,3'-二羟基-5,7, 4'-三甲氧基-4-苯基-香豆素。8,3',4'-三羟基-5,7-二甲氧基-4-苯基香豆素的取代模式也被分离出来,也通过化学反应得到证实。
