摘要
采用溶剂法、硅胶柱层析、Sephadex-LH20凝胶柱层析及重结晶等方法对鸡冠花(Celosia cristata L.)种子进行成分分离及纯化,并利用IR、1H-NMR、13C-NMR、MS等波谱技术鉴定提取物的化学结构。结果表明:从鸡冠花种子乙醇提取物中共分得6种化合物,经鉴定分别为对羟基苯乙醇(4-hydroxyphenethyl alcohol,1)、山奈酚(kaempferol,2)、槲皮素(quercetin,3)、β-谷甾醇(β-sitosterol,4)、2-羟基十八烷酸(2-hydroxyoctadecanoic acid,5)、豆甾醇(stigmasterol,6)。化合物1,4～6均为首次从该植物中分离得到。
To study the chemical chromatography, Sephadex LH-20 constituents of Celosia cristata Solvent extraction, silica gel column and recrystallization were used for the isolation and purification of the constituents. The structui＇es of the extracts were identified on the basis of spectral analysis, such as UV, IR,^1H-NMR,^13C-NMR and MS. Results showed： From the EtOH extract of Celosia cristata, 6 compounds were isolated and identified as 4-hydroxyphenethyl alcohol（1）, kaempferol（2）, quercetin（3）,β- sitosterol （4）, 2-hydrox-yoctadecanoic acid （5）, stigmasterol （ 6）. 1,4-6 compounds are isolated from Celosia cristata for the first time.
