Abstract
作者从Goniothalamus tamirensi 叶子中分离得到3个新化合物Gonitamirine、Goniotamiric acid、3,5-Demethoxypiperolide以及1 6个已知化合物.除化合物4,其余化合物均未显示出抗癌细胞活性. Goniothalamus tamirensis干燥粗粉(5.0 Kg)经25%氨水碱化,以乙酸乙酯室温提取,得乙酸乙酯提取物.乙酸乙酯提取物混悬于盐酸溶液中,以乙酸乙酯萃取,浓缩,得不含生物碱部分(54 g).剩余水液以10%碳酸钠水溶液中和至PH 8,分别以乙酸乙酯、二氯甲烷萃取,浓缩,分别得乙酸乙酯生物碱萃取物(43 g)、二氯甲烷生物碱萃取物(4.3 g).
