Abstract:
OBJECTIVE: To establish a RP-HPLC method for the simultaneous determination of Protocatechuic acid and Protocatechuic aldehyde in Fuxuekang granules. METHODS: The chromatography was carried on Achirom Bond-1 C18 column(250 mm?4.6 mm,5 ?m). The mobile phase was composed of methanol - water (20∶80,pH=2.80 adjusted by glacial acetic acid) at a flow rate of 1.0 mL?min-1. The detection wavelengths were programmed at 256 nm for Protocatechuic acid and at 280 nm for Protocatechuic aldehyde. RESULTS: The linear ranges for Protocatechuic acid and Protocatechuic aldehyde were 5.49～73.22 ?g?mL-1(r=0.999 9) and 4.81～64.13 ?g?mL-1(r=0.999 9), respectively, and their average recoveries were 96.86%(RSD=2.52%,n=9) and 97.55%(RSD=3.82%,n=9) respectively. CONCLUSION: The method is simple, sensitive, and reproducible, and it is applicable for the quality control of Fuxuekang granules.
