摘 要:目的:研究扁担杆的化学成分,寻找生物活性物质。方法:采用硅胶柱、MCI柱、Sephadex LH-20柱和Rp-18柱层析法分离、重结晶纯化化合物,根据理化性质、标准品薄层对照、波谱数据分析鉴定化合物结构。结果:从扁担杆根皮乙醇提取物的乙酸乙酯部位分离得到6个化合物,分别鉴定为木栓酮(1)、表木栓醇(2)、二十一烷酸(3)、β-谷甾醇(4)、棕榈酸丙酯(5)、儿茶素(6)。结论:化合物1—6均为已知化合物,其中1~3,5,6为首次从该属植物中分离得到,4为首次从该植物中分离得到。Objective: To investigate the chemical constituents of Grewia biloba and find its bioactive compounds. Methods:Compounds were isolated by silica gel, MCI,Sephadex LH-20 and Rp-18 column chromatography, and purified by recrystallization. Their structures were elucidated by spectral analysis and other methods. Results:Six compounds were isolated and identified as friedelin( 1 ), epi-friedelan-3-ol ( 2 ), heneicosanoic acid ( 3 ) , β-sitosterol (4), Propyl palmitate ( 5 ) , eatechin ( 6 ), respectively. Conclusion : Compounds 1 - 3,5,6 are isolated from Grewia genus for the first time and compounds 4 is isolated from Grewia biloba for the first time.
