Five xanthones have been isolated from Garcinia cowa Roxb. (Guttiferae): cowanin (1), cowanol (2), cowaxanthone (3), 1,3,6-trihydroxy-7-methoxy- 2-5-bis(3-methyl-2-butenyl)xanthone (4), and norcowanin (5). The structures were assigned by spectroscopic studies. Xanthones 2 and 3 showed moderate antimicrobial activity against Staphylococcus aureus.
从山竹子科的柯氏藤黄（Garcinia cowa Roxb.）中分离出了五种氧杂蒽酮：柯氏藤黄宁（1）、柯氏藤黄醇（2）、柯氏藤黄氧杂蒽酮（3）、1,3,6-三羟基-7-甲氧基-2,5-双（3-甲基-2-丁烯基）氧杂蒽酮（4）和去甲柯氏藤黄宁（5）。通过光谱研究确定了其结构。氧杂蒽酮2和3对金黄色葡萄球菌显示出中等抗菌活性。
