板栗种皮化学成分的分离与鉴定

目的研究板栗种皮的化学成分。方法采用硅胶柱色谱、凝胶柱色谱、氧化铝柱色谱和重结晶等多种分离方法对板栗种皮的体积分数为75%的乙醇提取物进行分离,通过化合物理化性质、谱学数据分析鉴定化合物结构。结果分离得到8个化合物,分别鉴定为软脂酸-1-甘油单酯(hexa-decanoic acid-2,3-dihydroxypropyl ester,1)、滨蒿内酯(scoparone,2)、异泽兰黄素(eupatilin,3)、5,7,4′-三羟基-6,3′-二甲氧基黄酮(jaceosidin,4)、5,7,4′-三羟基-6,3′,5′-三甲氧基黄酮(5,7,4′-trihy-droxy-6,3′,5′-methoxyflavone,5)、clovane-2,9-diol(6)、β-谷甾醇(β-sitosterol,7)、胡萝卜苷(dau-costerol,8)。结论化合物3~6为首次从栗属植物中分离得到。

Isolation and identification of chemical constituents from testa of Castanea mollissima Blume

Objective To study the chemical constituents from the testa of the Castanea mollissima Blume and elucidate their structures.Methods The compounds were isolated by column chromatography on silica gel,Al2O3 columns,together with recrystallization methods.NMR spectral analysis and physical-chemical properties were employed for the structural identification along with the data in the reference.Results Eight compounds were obtained and elucidated as hexadecanoic acid-2,3-dihydroxypropyl ester(1),scoparone(2),eup...
