Abstract From the stem bark of three previously uninvestigated Garcinia species a number of xanthones have been isolated including three that appear to be novel. The novel compounds are characterized as isocowanin (8-geranyl-4-(3,3-dimethylallyl)-7-methoxy-1,3,6-trihydroxyxanthone), isocowanol (8-geranyl-4-(3-hydroxymethyl-3-methylallyl)-7-methoxy-1,3,6-trihydroxyxanthone) and nervosaxanthone (4,8-di(3
摘要 从三个以前未经调查的藤黄属植物的茎皮中分离出许多氧杂蒽酮,其中三个似乎是新的。新化合物的特征为异豆蔻苷(8-香叶基-4-(3,3-二甲基烯丙基)-7-甲氧基-1,3,6-三羟基氧杂蒽酮)、异可豆醇(8-香叶基-4-(3-羟甲基-3-甲基烯丙基)-7-甲氧基-1,3,6-三羟基氧杂蒽酮)和神经黄嘌呤酮(4,8-二(3,3-二甲基烯丙基)-2-(1,1-二甲基烯丙基)-1,3,5,6-四羟基氧杂蒽酮) )。简要讨论了这些氧杂蒽酮中氧合模式的化学分类学意义。
