摘　　要：采用超声波法设计其正交试验,以大别山区金樱子多糖的含量检测为指标,在超声温度80℃,大别山金樱子原料液比1∶20,超声功率180 W,超声时间20 min条件下,测得金樱子多糖的平均含量为30.56%,与实验中最佳条件下测定值基本一致。通过探讨其回收和稳定性实验效果,进一步说明此方法准确度较高、重现性较好。In order to detection the content of polysaccharide form the fructus of Rosa laevigata Michx in the dabie mountain area,the orthogonal experiment should be designed by ultrasound method.The average content was 30.56% of the polysaccharide from Rosa laevigata Michx,under the determination conditions of 80 ℃,the ratio of liquid raw material about 1∶20,with ultrasonic power of 180 W,ultrasonic time of 20 min.The result was closed with the best possible experimental conditions.Therefore,by discussing the recovery and stability of the experiment effect,the result showed that this method was high accuracy and good reproducibility.
