Results TLC findings of Radix Sophorae Flavescentis and Radix Aucklandiae showed the spots of same colors as those developed in the corresponding places of control medical materials. Good liner was observed when the samplesize of dehydroandrographolide was within the range of 0.062～1.550 ?g (r =1.000 0). The average recovery rate was 98.00% with RSD=0.90%. Conclusion The method is simple, accurate, stable, reliable and with good reproducibility, which can be used for the quality control of Zhilining pill.
