[Abstract] Objective: To study on quality standard of Hedyotis Diffusae Wild. in the Qingshen granule. Method:Thin-layer chrmatography was used to identidy Hedyotis Diffusae Wild.
The content of Deacetyl asperulosidicacid methyl ester was determined by HPLC. The HPLC consisted of Kromasil C18 (4.6 mm ? 250 mm
5 μm)
acetonitrile-water (3.5: 96.5) as mobile phase
flow rate of 1.0 mL?min-1
detection wavelength at 276 nm. Result:The study on the quality control showed that the characteristic of identification by HPLC was distinct
accurate and reproducible.The linear range of Deacetyl asperulosidicacid methyl ester was 0.042 μg ~ 1.35 4 μg(r = 1.000 0). the average recovery was 99.96% With RSD of 1.66%(n = 6). Conclusion: The methods are accurate and quick in qualitative identification and quantitative assay of this preparation
can be used for the quality control of Qingshen granule.
