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．
