摘要
目的:从狗尾草果实中提取总鞣质并测定其含量。方法:采用超声波法提取狗尾草果实的总鞣质,用络合滴定法测定其总鞣质的含量。结果:狗尾草果实总鞣质的含量为0.4650%。结论:采用超声法提取操作程序简便、迅速,络合滴定法含量测定方法安全可靠,准确度和精密度较高,可用于狗尾草果实中总鞣质的提取及含量测定。
Objective：To extract total tannin from Setaria viridis（L.）Beauv.ripe fruits and determination the content of total tannin.Methods：It was adopted the optimum ultrasonic extraction technique to extract the total tannin from Setaira viridis（L.）Beauv.ripe fruits.Compleximetry was applied to determine the content of total tannin.Results：The content of total tannin was 0.4650%.Conclusion：Ultrasonic extraction technique is simple and rapid,Content determination of complexometric titration method is safe and reliable.The method was available for extraction and content determination of total tannin from Setaria viridis（L.）Beauv.ripe fruits.
