| Abstract: | OBJECTIVE： To establish the HPLC fingerprints of Apocynum Venetum leaves, determine the content of Quercetin in the sample and evaluate the variety and quality of commercial Apocynum Venetum leaves. METHODS： Quercetin was separated on Zorbarx - C18（250mm×4.6mm,5μm）, and the mobile phase consisted of methanol and 0.4% H3PO4（gradient elution） at a flow rate of 0.9 mL · min^ -1 with the detective wavelength set at 360 nm. RESULTS： The pre- cision of Quercetin was satisfactory（RSD = 0.21%, n = 6）, and the solution of Apocynum Venetum leaves was reproducible and stable within 10 hours. CONCLUSION： This study serves as a scientific basis for the identification and quality evalution of Apocynum Venetum leaves. |
