Objective:To establish a method for determination of gallic acid in [WTBX]Saxifraga stolonifera Curt.Method: The analysis was performed on a Kromasil C18 column
with the mixture of methanol and water with 0.1% phosphoric acid(10[DK]∶90)as mobile phase. The detection wavelength was at 271 nm.Result: The linear range of gallic acid was 0.117 2~0.703 2 μg. The average recovery was 96.48%. Conclusion:The method is simple and repeatable
and it co uld be used for the quantitative analysis of gallic acid in Saxifraga stolonifera Curt.
