摘要
在不同乙醇浓度（30％、60％、95％），不同固液比（1：8、1：10、1：2），不同温度（50℃、70℃、90℃）和不同提取时间（1h、2h、3h）等条件下，通过正交实验，对苦荞麦黄酮提取最佳条件进行了研究。结果表明：最佳提取工艺条件是60％乙醇，固液比为1：10，在50℃下振荡提取1h。
This paper studied the optimum technology condition of extracting tartary buckwheat flavonoid by means of normal experiment at thre elevel, that is, alcohol concentration (30%,60%,95% ), Solid - Liquid ratio (1: 8, 1: 10, 1: 12), extracting temperature (50℃,70℃, 90℃ ), and extracting time (1h, 2h, 3h). The result showed that the optimum extracting condition is ten times volumes 60% alcohol - water, temperature 50℃, vibrating extracting 1h.
