摘要
目的:研究白花蛇舌草水提取部位的化学成分。方法:药材水提取液用大孔吸附树脂、硅胶、MCI、Sephadex LH-20柱色谱、ODS中压液相色谱及半制备HPLC进行分离,并通过理化性质和波谱数据鉴定化合物结构。结果:从白花蛇舌草中分离得16个化合物,分别鉴定为:车叶草苷(1)、去乙酰车叶草苷(2)、京尼平苷(3)、10-去氢京尼平苷(4)、交让木苷(5)、diffusoside A(6)、diffusoside B(7)、松柏苷(8)、鸡屎藤次苷甲酯(9)、乙酰鸡屎藤次苷甲酯(10)、去乙酰车叶草酸苷甲酯(11)、羟异栀子苷(12)、水晶兰苷甲酯(13)、galioside 10-acetate(14)、地芰普内酯(15)、(+)-neo-olivil(16)。结论:其中,化合物3、8、14~16均为首次从该植物中分离得到。
Objective: To study the chemical constituents of water extracted fraction from Oldenlandia diffusa. Methods: The compounds were isolated and purified by column chromatography on macroporous resin,silica gel,MCI gel,Sephadex LH-20,ODS medium pressure liquid chromatography and RP-semi-preparative HPLC. The structures of compounds were elucidated on the basis of physicochemical and spectral analysis. Results: 16 compounds were isolated from the water extract of Oldenlandia diffusa,and their structures were identified as asperuloside( 1),deacetyl asperuloside( 2),geniposide( 3),10-dehydrogeniposide( 4),daphylloside( 5),diffusoside A( 6),diffusoside B( 7),coniferin( 8),scandoside methyl ester( 9),acetyl scandoside methyl ester( 10),deacetylasperulosidic acid methyl ester( 11),gardenoside( 12),galioside( 13),galioside 10-acetate( 14),loliolide( 15) and( +)-neo-olivil( 16),respectively. Conclusion: Compounds 3,8 and 14 ~ 16 are obtained from Oldenlandia diffusa for the first time.
