Objective To establish the quality standard of Folium Eucommiae Extract Dropping Pills and to investigate the stability un-der the condition of the room temperature and accelerated testing. Methods Chlorogenic acid in Folium Eucommiae Extract Dropping Pills was qualitatively identified by TLC;its content was determined by adopting HPLC. The chromatographic column was the Hypersic C18(250 mm × 4. 6 mm,5 μm),acetonitrile-0. 4% phosphoric acid solution(13 :87) was used as the mobile phase at the rate of 1. 0 mL/min. The detection wavelength was 327 nm and the column temperature was the room temperature. Results The chromato-graphic spots of samples were distinct with strong specificity and good reproducibility. The sample size of chlorogenic acid in the range of 1. 3 -130 μg/mL showed good linear relation with the peak area( r=0. 999 9 );the average recovery rate was 99. 81%( RSD=1. 28%,n=9);after the accelerated testing and the long-term testing,the various indexes of 3 batches of pilot test samples accorded with the quality standard of Folium Eucommiae Extract Dropping Pills. Conclusion Folium Eucommiae Extract Dropping Pills is excellent in stability;the established identification method is simple,accurate and reliable,and can be used for quality control of Foli-um Eucommiae Extract Dropping Pills.
