another known xanthonoid, tomentonone. Five known xanthones (3,8-dihydroxy-1,2-dimethoxy-, 1,3-dihydroxy-2,5-dimethoxy-, 1,5-dihydroxy-, 1,3,5-trihydroxy-2-methoxy- and 1,3,5-trihydroxyxanthone) and two flavonoids ((−)-epiafzelechin and (−)-epicatechin) were also characterized as constituents in the stem wood. Among them, apetalinone A was a novel xanthone with 1,1-dimethylallyl ether moiety, which indicated
摘要 从Calophyllum apetalum 的根中分离得到了三种新的类黄酮化合物apetalinones AC,以及已知的化合物calozeyloxanthone 和zeyloxanthonone。该物种的茎皮产生了一种新的类黄酮,apetalinone D 和另一种已知的类黄酮,tomentonone。五种已知的氧杂蒽酮(3,8-二羟基-1,2-二甲氧基-、1,3-二羟基-2,5-二甲氧基-、1,5-二羟基-、1,3,5-三羟基-2-甲氧基-和1,3,5-三羟基氧杂蒽酮)和两种黄酮类化合物((-)-epiafzelechin 和 (-)-epicatechin)也被表征为茎木中的成分。其中,apetalinone A 是一种具有 1,1-二甲基烯丙基醚部分的新型呫吨酮,表明了一种新的生物合成途径,包括 Claisen 重排和 Diels-Alder 反应。
