摘要
目的:从蒙药山川柳嫩枝叶中提取总鞣质并测定其含量。方法:采用浸泡与超声波相结合法提取山川柳嫩枝叶的总鞣质,用配位滴定法测定其总鞣质的含量。结果:总鞣质的含量为4.728%。结论:采用浸泡、超声法提取操作程序简便、实用,本文采用配位滴定法含量测定,方法独特、细致全面,准确度和精密度较高,可用于山川柳嫩枝叶中总鞣质的提取及含量测定。
Objective：To extract total tannin from Mongolian medicine （ramulus Tamarixis＇ tender foliage ） and determination the content of total tannin. Methods： It was adopted soaking with the optimum ultrasonic extraction technique to extract the total tannin from Ramulus Tamarixis＇ tender foliage. Complexometry was appliedto determine the content of total tannin. Results： The content of total tannin was 4. 728%. Conclusion ：The method of soaking with ultrasonic extraction technique is simple and practical, Content determination of compleximetric titration method is unique and considerate. The method was available for extraction and content determination of total tannin from Ramulus Tamarixis＇ tender foliage.
