探索了吸附树脂柱色谱法脱除辣椒色素中辣椒素的新方法.该方法可将辣椒色素与辣椒素分离并对红、黄色素组分实现初步分离,辣椒色素产品色价高达105.用硅胶柱色谱法可分离辣椒色素精细组分.对所得色素精细组分进行了紫外-可见光谱分析表明:红色素组分的最大吸收波长为470 nm,黄色素组分的最大吸收波长为450 nm;各辣椒色素组分的光稳定性也存在较大的差异,为辣椒色素各精细组分充分而有效的利用提供了理论依据.

In this paper, a new method eliminating capsaicinoids from pepper pigment was studied by using adsorption resin column chromatography. Red colour and Yellow cnlour composition without capsaicinoids were obtained and the value of Red colour composition get to 105. Pigment ingredient could be separated finely by using Si-gel column chromatography . Several Red colnur with the maximum adsorption wavelength 470 nm and Yellow colnur with the maximum adsorption wavelength 450 nm in uv-vis spectra were obtained. Stability experiment showed that different eolour has different Stability under sun-light...
