Abstract The stem bark of a species of Garcinia (Guttiferae), provisionally identified as G. densivenia , has yielded a xanthone and two biflavonoids. The xanthone has been characterized as a novel 1,3,5,6-tetraoxygenated compound and has been assigned the trivial name pyranojacareubin (1,5-dihydroxy-6′,6′-dimethylpyrano (2′,3′:3,2)-6″,6″-dimethylpyrano (2″,3″:6,7)-xanthone). The biflavonoids were
摘要 一种藤黄科(Guttiferae)的茎皮,暂时鉴定为 G. densivenia,产生了一种呫吨酮和两种双黄酮。呫吨酮已被表征为一种新型的 1,3,5,6-四氧化化合物,并被指定为 pyranojacareubin (1,5-dihydroxy-6',6'-dimethylpyrano (2',3':3,2 )-6",6"-二甲基吡喃 (2",3":6,7)-氧杂蒽酮)。双黄酮类化合物被鉴定为羊肚菌黄酮及其甲基醚衍生物,O-甲基福吉丁。
