Fingerprint of Flos Lonicerae by HPLC-FPC / 中成药

ABSTRACT

AIM To establish the HPLC-FPC of Flos Lonicerae . from different growing areas. METHODS The gradient was adopted elution with methanol and 1 % acetic acid, at detection wavelength was at 254 nm. RESULTS The constitutents of Flos Lonicerae were well separated on HPLC, and the HPLC-FPC of 10 batchs of samples was established. The results showed that this method had a good repeatability, and the 11 common peak’s had an exclusive properties. CONCLUSION The method developed can evaluate the quality of Flos Lonicerae conveniently.
