摘　　要：优选桃花红色素的最佳提取工艺。方法:优选溶剂后,采用正交试验,以提取桃花红色素的得率为指标,对桃花浸泡时间、提取温度及超声时间进行优选研究。结果:浸提桃花红色素宜选溶剂为50%的乙醇溶液,在所考察因素中,桃花红色素的最佳提取工艺是A2B2C2。结论:优选所得工艺稳定可行。Objective： To explore an optimum extraction technology of red pigment from peach blossom. Methods： After the 50% ethanol was chosen as the solvent, orthogonal design was carried out to find the optimum extraction technology by detecting the extracting ratio, among the breaking-up degree of the blossoms, soaking time, extracting time and adding water. Results： The optimum extraction technology was A2B2C2. Conclusion： The optimized technology was stable and feasible.
