目的:研究鸭跖草科裸花水竹草的化学成分。方法:采用硅胶柱色谱、重结晶等方法分离和纯化,并通过IR,EIMS及NMR等波谱学方法对分离得到的化学成分进行结构鉴定。结果:从裸花水竹草中共分离得到15个化合物,分别为正三十九烷(1),二十烷酸辛酯(2),胆甾-7-烯-3-酮(3),22,23-二氢菠菜甾酮(4),二十四烷酸(5),三十烷酸(6),谷甾醇(7),菜油甾醇(8),豆甾醇(9),麦角甾醇(10),豆甾-7-烯-3-醇(11),豆甾醇-3-O-葡萄糖苷(12),胡萝卜苷(13),二十七烷酸甘油酯(14),bracteanolide A(15)。结论:其中化合物1~15均为首次在该植物中分离得到。
OBJECTIVE: To study the chemical composition of Hydrangea japonica in Compositae. Methods: The constituents were separated and purified by silica gel column chromatography and recrystallization. The chemical constituents were identified by IR, EIMS and NMR spectroscopy. Results: A total of 15 compounds were isolated from Phragmites australis, n-nonacosane (1), octyl estradiol (2), cholest-7-en-3-one (4), lignoceric acid (5), triacontanoic acid (6), sitosterol (7), campesterol (8), stigmasterol (9), ergosterol 10), stigmasterol-7-en-3-ol (11), stigmasterol-3-O-glucoside (12), daucosterol (13), glyceryl heptacosane (14) 15). Conclusion: Compounds 1-15 were isolated from this plant for the first time.
