Abstract From the unripe seeds of Cassia torosa three new dimeric hydroanthracene derivatives were isolated along with stigmasterol, sitosterol, campesterol, physcion-9-anthrone, torosachyrsone and the phlegmacins A 2 and B 2 . The structures of the new derivatives were established as physcion-10, 10′-bianthrone, anhydrophlegmacin B 2 [2-(6′-methoxy-3′-methyl-3′, 8′, 9′-trihydroxy-1′-oxo-1′, 2′, 3′
摘要 从决明子的未成熟种子中分离到了三种新的二聚氢蒽衍生物以及豆甾醇、谷甾醇、菜油甾醇、physcion-9-蒽酮、牛角草酮和粘液素A 2 和B 2 。新衍生物的结构确定为physcion-10, 10'-bianthrone, anhydrophlegmacin B 2 [2-(6'-methoxy-3'-methyl-3', 8', 9'-trihydroxy-1'-oxo -1', 2', 3', 4'-四氢蒽-10'-基)-1, 8-二羟基-3-甲氧基-6-甲基-9-氧代-9, 10-二氢蒽] 和 torosanin [2- (6'-甲氧基-3'-甲基-3', 8',9'-trihydroxy-1'-oxo-1', 2', 3',4'-四氢蒽-5'-yl)-1, 8 -二羟基-3-甲氧基-6-甲基-9-氧代-9,10-二氢蒽],分别。
