分心木化学成分的研究

Chemical Constituents from Diaphragma Juglandis Fructus

目的研究分心木的化学成分。方法应用柱色谱法分离和纯化,通过理化常数和波谱分析鉴定化合物的结构。结果从分心木乙醇提取物中分离得到12个单体化合物,分别鉴定为:胡桃苷A(1),核桃素D(2),没食子酸(3),没食子酸乙酯(4),原儿茶酸(5),槲皮素(6),二氢槲皮素(7),儿茶素(8),槲皮苷(9),槲皮素-3-O-(6''-没食子酰基)-β-D-半乳糖苷(10),β-谷甾醇(11)和胡萝卜苷(12)。结论化合物1,5,6,9,10,12为首次从分心木中分离得到。

Objective To investigate the chemical constituents of Diaphragma juglandis Fructus.Methods The compounds were isolated and purified by column chromatography and their structures were elucidated on the basis of physical characteristics and spectral data.Results Twelve compounds were isolated and their structures were identified as juglanin A（1）,juglanin D（2）,gallic acid（3）,progallin A（4）,protocatechuic acid（5）,quercetin（6）,dihydroquercetin（7）,catechin（8）,quercitrin（9）,quercetin-3-O-（6＇＇-galloyl）-β-D-galactopyranoside（10）,β-sitosterol（11） and daucosterol（12）.Conclusion Compound 1,5,6,9,10 and 12 can be isolated from Diaphragma juglandis Fructus for the first time.
