摘　　要：用正交试验优化苜蓿黄酮的提取工艺。在不同的提取温度、提取时间和溶剂体积的条件下,对苜蓿总黄酮进行提取试验。结果表明:水提法的最佳工艺为提取温度90℃,提取时间4h,固液比1:40,该条件下苜蓿总黄酮的提取率为5.862mg/g。To optimize the best water extraction technics of total flavonoids in alfalfa by orthogonal test at different extraction temperature, extraction time and solvent volume conditions, the results showed that the optimal water extraction technics were as follows： extraction temperature was 90℃, extraction time was 4 h, and solid to liquid ratio was 1：40. Under this condition the water extraction rate of total flavonoid in alfalfa was 5.960 mg/g.
