从乌藨子根皮中分得两个新的外消旋C-苄基化二氢黄酮。番荔枝科（番荔枝科）[一种可能的药用植物]。根据光谱数据和转化为已知化合物，提出其结构为二金刚烷和金刚烷的5-甲基醚衍生物。本文讨论了几种金刚烷甲醚衍生物和金刚烷甲醚衍生物的~（13）C NMR数据。
Two new racemic C-benzylated flavanones were isolated from the root bark of U. chamae (Annonaceae) [a possible medicinal plant]. The structures were proposed as the 5-methyl ether derivatives of dichamanetin and chamanetin based on spectral data and conversion to known compounds. The 13C NMR data for a number of methyl ether derivatives of chamanetin and dichamanetin are discussed.
