摘要
目的:研究彝药透骨草的化学成分,为探究其活性物质奠定基础。方法:反复运用正相硅胶柱色谱、重结晶、制备高效液相等手段,从透骨草的乙醇提取物中分离纯化单体化合物,并运用MS、1H-NMR、13C-NMR、2D-NMR等波谱方法鉴定所分离化合物的结构。结果:从透骨草的乙醇提取物中分离得到5个化合物,分别鉴定为:熊果酸(1)、槲皮素(2)、异香草酸(3)、对羟基苯甲酸(4)、阿糖腺苷(5)。结论:其中,化合物2~5均为首次从该属植物中分离得到。
Objective: To study the chemical constituents of Phryma leptostachya. Methods: The chemical constituents were isolated and purified by silica gel column,recrystallization and Pre-RP-HPLC and their structwes were elucidated by spectroscopic methods. Results: Five compounds were obtained and identified as ursolic acid(1),quercetin(2),isovanillic acid(3),p-hydroxybenzoic acid(4),adenine arabinoside(5).Conclusion: Compounds 2~5 are isolated from this genus for the first time.
