本文对红花红色素的超声提取方法进行了研究，通过单因素试验和正交设计试验确定超声提取红花红色素的影响因素并筛选其优化提取条件，采用分光光度法测定其含量，并用色价来衡量。实验结果表明，提取红花红色素的最佳溶剂为70%丙酮，其最佳提取条件为：超声时间30 min，提取两次（30 min，30 min），超声温度40 ℃，固液比1:12（m/v）。

This paper studied the ultrasonic wave extraction process of Safflower Red from safflower. Single factor test and orthogonal test were applied to analyze the effects of the key factors. Spectroscopic analysis and Color value method were adopted to determine the absorbency and to measure the content of Safflower Red, respectively. The optimal acetone concentration, extraction time, extraction times, temperature and the ratio of sold/liquid were 70%, 30 min, 2, 40 ℃ and t 1:12, respectively.
