				        	Objective: To determine the content of tetrahydropalmatine in Yuanhuzhitong Dropping Pills by TLC  scanning.  Methods: The extraction solution of the sample was analyzed on silica gel  G plate, with toluene  anhydrous alcohol (20∶2, saturating for 30 min) as the developing system. The spot was located under UV (at 254nm), then detected by dual wavelength scanning (?  S=280nm,?  R=310nm).  Results: The average recovery was 98.90%. RSD was 3.10%. Conclusion: The method is simple, accurate and available for the quality control of Yuanhuzhitong Dropping Pills.
