辣椒的乙醇提取物经稀乙醇萃取后,用大孔吸附树脂柱以含水乙醇为洗脱剂富集辣椒素.研究了从辣椒提取物中初步分离辣椒素与色素的乙醇浓度,体积分数为40%的乙醇萃取物中辣椒素的含量达到0.42g/L,回收率为78%.考察了11种大孔吸附树脂对辣椒素类物质的静态吸附与解吸的分离性能,筛选了一种富集辣椒素的大孔吸附树脂D01,静态饱和吸附容量为26.1 mg/g.进一步研究了D01树脂对辣椒素的动态吸附与解吸性能,动态饱和吸附容量为16.0 mg/g,以体积分数40%乙醇溶解辣椒提取物后上D01型大孔吸附树脂柱,以体积分数70%乙醇解吸,回收溶剂后的油膏体经HPLC检测,辣椒素从辣椒提取物中的1.5%富集到81.7%,回收率为78....

Capsaicinoids was isolated and purified by 40% ethanol extraction, followed by macroporous adsorption resin column chromatography with 70% ethanol as elutent from extract of Capsicum frutescens L.. The concentration of ethanol, isolated capsaicinoids from pigment primarily, was studied. A solution contained capsaicinoids 0. 42 g/L was obtained by extraction separation with 40% ethanol from the extract of Capsicum frutescens L. with a recovery ratio of 78%. A macroporous adsorption resin was selected as the medium for the purification of capsaicinoids after comparing static adsorption and eluti...
