OBJECTIVE:To establish a TLCS method for determination of Rutin in Flos sophorae.METHOD:A TLCS method was used.The developer was ethyl accetate butanone butanol formic acid water(10∶6∶1∶2∶2)and the determination wavelength was 360nm.RESULTS:The regression equation was Y=0.3422+2 1917×10 -4 x.(r =0 9997).the average recovery was 98 55%, RSD =1 39%( n =5)。CONCLUSION:This method is simple and sensitive with good repeatability.
