Abstract

Objective To establish the chromatography fingerprint of Radix Scrophulariae by RP-HPLC.Methods HPLC was applied in this study.Kromasil KR100-5C18(4.6 mm× 250 mm,5 μ m)column and DAD detector were used with a mixture of methanol and 0.1 % methanoic acid as mobile phase in a gradient mode.Results The chemical substances of Radix Scrophulariae were optimally separated.Conclusion This method is simple,accurate with good reproducibility,thereby can be used specifically for the quality control of Radix Scrophulariae.
