【摘要】 紫薇花天然色素因具有安全性和着色效果好,在食品与工业领域中应用广泛。本文以紫薇花为原料,对紫薇花色素进行了初步的纯化。在此基础上研究了紫薇花色素的化学性质、并采用紫外-可见光谱及液相色谱进行了分析。通过特征颜色反应、紫外光谱及液相色谱图,验证紫薇花色素属于花色苷类化合物,且存在6种花色苷成分,为进一步鉴定、分析花色苷组成垫定基础。更多还原

【Abstract】 As Crape myrtle flower pigments is safety and shading effect is good,it is widely used in food and industrial fields. Used crape myrtle flower as raw material,the preliminary purification of crape myrtle flower pigment was carried on. On the basis of the study,the chemical properties were studied and analyzed by UV- VIS spectra and liquid chromatography. Through the characteristics of the color reaction,ultraviolet spectrum and liquid chromatogram,the flower pigment was proved as part of the anthocyanins compounds,and there were 6 kinds of anthocyanins.更多还原
