To study xanthones from the barks of Garcinia xanthochymus, the constituents were isolated by normal-phase and reverse-phase silica gel column chromatography from the EtOAc extract. Their structures were elucidated by spectral analysis. Three new xanthones were purified and identified as 1,2,5-trihydroxy-6-methoxyxanthone (1), 1,4,6-trihydroxy-5-methoxyxanthone (2), 1,2,7-trihydroxy-4-(1,1-dimethylallyl) xanthone (3).
为了研究山竹子树皮中的氧杂蒽酮，通过正相和反相硅胶柱色谱法从乙酸乙酯提取物中分离出其成分。通过光谱分析阐明了它们的结构。纯化并鉴定出三种新的氧杂蒽酮，分别为1,2,5-三羟基-6-甲氧基氧杂蒽酮（1）、1,4,6-三羟基-5-甲氧基氧杂蒽酮（2）、1,2,7-三羟基-4-(1,1-二甲基烯丙基)氧杂蒽酮（3）。
