Abstract Three new xanthone derivatives, 11-hydroxy-1-isomangostin, a xanthonolignoid (5′-demethoxycadensin G) and a bisxanthone, as well as the known compound 1,3,5,6-tetrahydroxyxanthone, were isolated from the bark of Cratoxylum cochinchinense. Their structures were elucidated mainly by a combination of high-field NMR spectroscopic techniques.
摘要 从 Cratoxylum 的树皮中分离得到 3 种新的呫吨酮衍生物,11-羟基-1-异芒果素,一种黄酮木素(5'-脱甲氧基卡登素 G)和一种双黄酮,以及已知的化合物 1,3,5,6-四羟基黄酮。胭脂虫。它们的结构主要通过高场核磁共振光谱技术的组合来阐明。
