ABSTRACT
Objective To control the quality of Gongyankang granule.Methods Paconiflorin in Gongyankang granule was determined by HPLC,using a Phenomenex Prodigy Thermouest(250×4.6 mm 5μm BDS C18).Mobile phase was consisted of CH_2OH-H_2O-H_3PO_4(30:70:0.1)with the UV detector set at 230 nm.Results The paeoniflorin showed linear correlation(r=0.9998)within the range of 0.01026～0.06156mg.The average recovery rate was 99.12%with RSD of 1.61%.Conclusion This method was simple,accurate and with good reproducibility,thus it can be used for quality control of Gongyankang Granule.
ABSTRACT
Objective To control the quality of GongYanKang Granule. Methods Radix Paeoniae Rubra, Corydalis and Radix Angelicae Sinensis of Gongyankang Granules were identified by TLC. Results Qualitative identification to Radix Paeoniae Rubra, Corydalis and Radix Angelicae Sinensis in GongYanKang Granules by TCL showed that this method has negative interference, clear spots and good resolving powder. Conclusion This method is simple and accurate with good reproducibiliy, being suitable for quality control of Gongyankang Granule.
