Abstract:

目的:研究版纳藤黄Garciniaxipshuanbannaensis枝叶的化学成分。方法:利用正相硅胶、反相RP-18柱色谱及葡聚糖凝胶SephadexLH-20等手段进行分离纯化,根据波谱数据鉴定化合物的结构。结果:分离鉴定了15个化合物,分别为bannaxanthoneE(1),大叶藤黄醇(xanthochymol,2),异大叶藤黄醇(isoxanthochymol,3),环大叶藤黄醇(cycloxanthochymol,4),osajaxanthone(5),gentisein(6),mangostinone(7),山柰酚(8),槲皮素(9),牡荆素(10),2″-O-acetylvitexin(11),3-乙酰齐墩果酸(12),(-)-表儿茶素[(-)-epicatechin,13],β-谷甾醇(14),胡萝卜苷(15)。结论:化合物4~9,11~13为首次从该种植物分离得到,化合物11~13为首次从该属植物分离得到。
