METHODS: Hypersil ODS2 C_18(4.6 mm?250 mm,5 ?m) column was used,with mixtures of 0.1%TFA solution and acetonitrile as mobile phase in a gradient mode.The flow rate was 1.0 mL/min,the column temperature was at 30 ℃,detection wavelength was at 254 nm. RESULTS: HPLC fingerprint determination with 22 common peaks gained from 10 batches of self-made Tonfengyu Dropping Pill,there were 9 components identified,including caffeine,EGCG,ferulic acid,oxypeucedanin,imperatorin,phellopterin,cnidilin,isoimperatorin and oxypeucedanin hydrate.
