Objective: To develop an HPLC-DAD fingerprint to conduct a quantitative analysis on the 14 index ingredients of Gegen Tang (GGD) and provide a method for the quality control for the water extracts from GGD. Method: The AgelaVenusil MP-C18was adopted and eluted in gradient with acetonitrile and water (consisting 0.1% formic acid) at 30 ℃. The flow rate was 1.0 mL · min-1
and the detection wavelength was set at 207
230
254 and 275 nm. Result: Totally 38 common peaks were marked and 10 were identified in this fingerprint
with a good similarity (≥0.978) and less difference among the 11 batches. Specifically
14 index components in the 11 batches of GGD feature even and stable content
stable sample preparation method and controllable quality. Conclusion: The combination of fingerprint and quantitative analysis can roundly reflected the quality of GGD and can be taken as an effective method for controlling the quality of the water extracts from GGD.
