- W2373172325 abstract "OBJECTIVE:To establish an HPLC method for determination of protocatechuic acid in Pterospermum heterophyllum.METHODS: The separation was performed on Agilent TC C18(250 mm×4.6 mm,5.0 μm)column.Moblie phase consisted of acetonitrile-0.1% glacial acetic acid solution(pH 3.16,10 ∶ 90)with flow rate of 1.0 mL·min-1 and detection wavelength of 260 nm.The column temperature was set at 35℃ and injection volume was 10 μL.RESULTS:The linear range of protocatechuic acid was 0.007 76～0.310 4 μg(r=0.999 7) with an average recovery of 97.68% (RSD=1.51%,n=6).CONCLUSION:The method is simple,accurate and reproducible for the quality control of P.heterophyllum." @default.
