摘　　要：通过单因素试验和正交试验方法确定枇杷叶中黄酮类化合物的最佳提取工艺。结果表明,用频率为69 kHz的超声波,以70%乙醇为溶剂,料液比为1∶10,处理时间45 min,温度为55℃,提取枇杷叶中总黄酮的浸出率最高。Using the single factor experiment and orthogonal experiment method,the optimum extracting condition of flavonoids in loquat leaves was investigated.The results showed that the optimum processing condition was ultrasonic-wave frequency of 26 kHz,extraction time of 45 min,ration of material to solvent of 1∶10,solvent of 70% ethanol and temperature of 55 ℃.
