摘　　要：以玫瑰花为原料提取色素,对浸提剂种类、pH值、浓度、物料比、提取温度、提取时间进行了研究,通过正交试验优化了玫瑰花色素的提取工艺,结果表明,体积分数为70%乙醇、pH值为1、物料比为1 g 8 mL、浸提温度为60℃、时间为60 min为最佳提取条件.This paper has taken the red rose as raw material to extract rose pigment, and studied the type of extraction solvent, the pH value, the density of extraction solvent, the material rate, extraction temperature, and extraction time. In order to optimize the rose pigment extraction process, the orthogonal test was adopted. The research obtained the optimal extraction conditions, as following： the most suitable extraction solvent is 70% （V/V） ethyl alcohol, the pH value is 1, the material rate （m/V） is 1：8, the temperature is 60℃, and the time is 60 min.
