Abstract Two novel lactones have been isolated from the stem barks of Garcinia conrauana and G. mannii . The major component of the bark of G. conrauana was identified as 3-(3 , 3″-dimethylallyl)-conrauanalactone [4-hydroxy-3-(3″, 3″-dimethylallyl)-6-pentadecylpyran- 2-one] by comparison of spectral data of the isolated compound and two methylethers with that obtained for the previously isolated conrauanalactone
摘要 从Garcinia conrauana 和G. mannii 的茎皮中分离到了两种新的内酯。G. conrauana 树皮的主要成分被鉴定为 3-(3 , 3″-二甲基烯丙基)-conrauanalactone [4-hydroxy-3-(3″, 3″-二甲基烯丙基)-6-pentadecylpyran-2-one]通过将分离的化合物和两种甲基醚的光谱数据与先前分离的康劳内酯的光谱数据进行比较。G. mannii 树皮的一个次要成分被初步鉴定为 3-α-hydroxy-5-(heptadec-8'-enyl)-tetrahydro-furan-2-one。单醋酸盐。报道了这两个物种的茎皮、心材、种子和叶子中双黄酮类化合物和相关化合物和二苯甲酮的分布。
