| Abstract: | Objective To establish a method for determining gallic acid in Polygoni Cuspidati Rhizoma et Radix Compound burn gels by HPLC.Methods An HPLC method was performed on a Rromsil C18 column（150 mm×4.6 mm,5 μm） with methanol-0.1%phosphoric acid solution（15：85） as mobile phase.The detecting wavelength was set at 273 nm,the flow rate was 1.0 mL·min^-1 and the column temperature was 25 ℃.Results The calibration curve of gallic acid was linear in the range of 0.119～0.792 μg（r=0.999 7）and the average recovery rate was 99.5% with RSD of 1.93%（n=5）.Conclusion The method was simple,accurate and reproducible for the quality control of Polygoni Cuspidati Rhizoma et Radix Compound burn gels. |
