Improvement of Quality Standard for Dashanzha Granules
Objective To improve the quality standard of Dashanzha Granules.Methods Crataegi Fructus in the samples was identified qualitatively by the thin-layer chromatography(TLC)method.The content of hyperoside in the samples was determined by the ultraviolet-visible spectrophotometry at a wavelength of 500 nm.Results The TLC chromatograms of Crataegi Fructus showed clear characteristic spots,good resolution,and there was no interference from the negative reference.The linear range of hyperoside was 0.004 9-0.049 0 mg/mL(R2=0.999 7,n=6).The RSDs of precision,stability and repeatability tests were all lower than 2.0%.The average recovery rate of hyperoside was 100.10%with an RSD of 0.64%(n=6).The average content of hyperoside in the samples was 38.26 mg per bag.Conclusion The established method is simple,accurate and reliable,which can be used for quality control of Dashanzha Granules.
