Quality standard for Yinhua Mangguo Granule / 中成药

AIM: To establish the HPLC-FPC of Yinhua Mangguo extract(Flos lonicerae japonicae,Folium Mangiferae,Pericarpium Citri reticulate,etc.). METHODS: The gradient elution was adopted with acetonitrile,methanol and 0.05% phosphoric acid as a mobile phase.The detection wavelength was at 238 nm. RESULTS: The components of Yinhua Mangguo extract were well separated on HPLC,and the HPLC-FPC of 10 batches of samples was established.The results showed that this method had a good repeatability,and the 12 common peaks had an exclusive properties. CONCLUSION: The method developed can evaluate the quality of Yinhua Mangguo extract.

Fingerprint of Flos Lonicerae by HPLC-FPC / 中成药

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.
