A new bitetrahydroanthracene derivative, torosaol-III, was isolated from the flowers of Cassia torosa Cav. along with physcion, 5,7'-physcionanthrone-physcion, 5,7'-biphyscion, torosanin-9,10-quinone, 5,7-dihydroxy-chromone, naringenin, and chrysoeriol. The structure of torosaol-III was established as 3,3'-4,4'-tetrahydro-3,3'8,8'9,9'-hexahydroxy-6,6'-dimethoxy-3,3'- dimethyl-1(2H),1'(2H)-5,7'-bianthracenone
从决明子桃冠花的花中分离出一种新的双四氢蒽衍生物,即桃冠酚-III。以及physcion,5,7'-physcionanthrone-physcion,5,7'-biphyscion,torananin-9,10-quinone,5,7-dihydroxy-chromone,naringenin和chrysoeriol。甲苯酚-III的结构确定为3,3'-4,4'-四氢-3,3'8,8'9,9'-六羟基-6,6'-二甲氧基-3,3'-二甲基-根据光谱和化学证据,得出1(2H),1'(2H)-5,7'-联蒽酮。二聚四氢蒽在组织培养物中对KB细胞表现出细胞毒活性。
