摘要
目的对板栗种仁的药用保健部位进行化学成分的研究。方法从板栗药用保健部位的乙酸乙酯提取部位经过多次硅胶柱色谱和薄层色谱分离化学成分,经理化常数测定、波谱分析、标准品比较和文献等鉴定出结构。结果分离得到7个化合物,分别为尿嘧啶(uracil,1)、正丁基-吡喃果糖苷(n-butyl-β-D-fructopyranoside,2)、壬二酸(azelaic acid,3)、异庚酸(isoenanthic acid,4)、蔗糖(su-crose,5)、β-谷甾醇(-βsitosterol,6)、胡萝卜苷(daucosterol,7)。其中化合物1-4为属内首次分离得到,化合物5为种内首次分离得到。
Objective To isolate and identify the compounds from the EtOAc fraction of 90 % EtOH extract mollissima Blume. Methods Compounds were isolated by the silica gel and Sephadex their structures were identified by the physicochemical characters and spectral analysis.Results Seven compounds were obtained and identified as uracil （1）, n-butyl-β-fructopyranoside （2）, azelaic acid （3）, isoenanthic acid （4）, sucrose （5）, β-sitosterol （6）, daucosterol（7）. Conclusions Compounds 1-4 are obtained from Cstanea genus for the first time.
