目的　研究醉鱼草 (Buddlejalindeyana)的活性成分。方法　应用多种色谱技术分离纯化 ,用IR ,MS和NMR等谱学方法解析化合物结构。结果与结论　从醉鱼草 (Buddlejalindeyana)的全草分离到 5个化合物 ,其中三个为环烯醚萜苷。它们的结构为 :6 氧 阿魏酰筋骨草苷 (1) ,赤式 6 氧 4′ (3 甲氧基 4 羟基苯丙三醇 8″) 阿魏酰筋骨草苷 (2 ) ,苏式 6 氧 4′ (3 甲氧基 4 羟基苯丙三醇 8″) 阿魏酰筋骨草苷 (3) ,二十四烷酸 α 单甘油脂 (4 ) ,半乳糖醇 (5 )。上述成分均为首次从醉鱼草中得到。且化合物 1,2和 3对神经细胞有保护作用 Objective To study the active ingredients of Buddlejalindeyana. Methods A variety of chromatographic techniques were used to separate and purify the compounds. IR, MS and NMR were used to analyze the structure of the compounds. Results and conclusions Five compounds were isolated from the whole grass of Buddlejalindeyana, of which three were iridoid glycosides. Their structures are: 6-oxo-feruloyl ajura glycosides (1), erythroxy 6-oxo 4’ (3 methoxy 4-hydroxy phenyl glycerol 8“), feruloyl acrorasin (2 ), and threo 6 Oxygen 4’ (3 methoxyl 4 hydroxyphenyl glycerol 8”) feruloyl acronosine (3), tetracosanoic acid alpha monoglyceride (4), galactitol (5). The above ingredients were first obtained from Buddleja. Compounds 1, 2 and 3 have protective effects on nerve cells.
