摘要
本文研究了川山紫薯色素(purple-fleshed sweet potato anthocyanin, 简称PSA)乙醇提取最佳工艺条件,分析了紫薯色素主要组成成分。实验结果表明:乙醇提取PSA的最佳条件为:提取酸浓度2.0 %、提取时间为60min、提取固液比1:30。反相高效液相色谱法(RPHPLC)分析表明,PSA主要含矢车菊色素-3-葡萄糖,酰化酸为绿原酸和芥子酸。
The optimal ethanol extraction technical conditions and main constituent analysis of purple-fleshed sweet potatoanthocyanin (PSA) from species originally produced in Japan were studied in this paper. The results suggested that the optimalethanol extraction technical conditions were 2.0% of the extraction acid concentration, 60minutes of extraction time and 1:30 ofthe rate of solid to liquid. The reverse phase HPLC (RPHPLC) investigation showed that the main constituent of PSA wascyanidin-3-glucoside, which was acylated mainly by chlorigenic acid and sinapinic acid.
