摘要:Objective To study the chemical constituents in Rubus corchorifolius. Methods Chromatography on silica gel column, Sephadex LH-20 columm, recrystallization and preparative HPLC technique were used to isolate and purify the compounds. Spectroscopy methods including UV, IR, EI-MS, ES-MS and NMR were used to elucidate the structures of compounds. Results Ten compounds were obtained and identified as : stigmasterol ( 1 ) , beta-sitosterol ( 2) , daucosterol ( 3 ) , 4-hydro-3-methlbenzal acid ( 4) , apigenin ( 5 ) , luteolin ( 6 ) , Homofukinolide ( 7 ) , Bakkenolide-B ( 8) , Bakkenolide-D ( 9) , 3 ,5 ,9-trihydroxy-7 ,8-dihydrocyclopenta [g]chromene-2 ,6-dione(10). Conclusion Compound 4, 5, 6, 7, 8, 9 were isolated from Rubus corchorifolius for the first time. Compound 10 was a new compound.%目的 对山莓的化学成分进行研究.方法 采用硅胶柱色谱、Sephadex-20柱色谱、重结晶,并经高效液相色谱等技术提取分离山莓的化学成分,用UV、IR、EI-MS、ES-MS及NMR等光谱方法鉴定化合物结构.结果 从山莓乙醇提取物的石油醚部位分离得到化合物1~6,分别鉴定为豆甾醇(1)、β-谷甾醇(2)、胡萝卜苷(3)、Homofukinolide(4)、Bakkenolide-B(5)、Bakkenolide-D(6);从二氯甲烷部位分离得到化合物7~10,分别鉴定为4-羟基-3-甲氧基苯甲酸(7)、芹菜素(8)、木樨草素(9)、山莓素(10).结论 化合物4、5、6、7、8、9首次从山莓子中分离得到,化合物10是新化合物.
