摘要
目的:研究了洋葱籽(The seeds ofAllium cepaL.)的化学成分。方法:运用硅胶柱色谱、大孔树脂HP-20、Sephadex LH-20、反相C-18柱层析进行分离纯化。结果:从洋葱籽乙醇提取物中分离得到了7个化合物,通过理化性质和波谱分析分别鉴定为天师酸(Ⅰ),N-trans-feruloyl tyramine(Ⅱ),β-sitosterol-3β-glucopyranoside-6’-palmi-tate(Ⅲ),β-谷甾醇(Ⅳ),胡萝卜苷(Ⅴ),色氨酸(Ⅵ),腺嘌呤核苷(Ⅶ)。结论:化合物Ⅴ~Ⅶ为首次从该植物中分离得到,化合物Ⅰ~Ⅳ是首次从该属中分离得到。
Objective: To study the chemical constituents from the seeds of Allium cepa L.,The constituents of the seeds of Allium cepa L..Methods: To isolate and purifie by silica gel,macroporous resin HP-20,Sephadex LH-20,RP-18 column.Results: Seven compounds were isolated from the EtOH extract of the seeds of Allium cepa.,their structures were elucidated by physico-chemical properties and spectroscopic analysis as tianshic acid(Ⅰ),N-trans-feruloyl tyramine(Ⅱ),β-sitosterol-3 β-glucopyranoside-6 -palmitate(Ⅲ),sitoster...
