RESUMO
Objective To establish a method for the determination of forsy thin in Baohe Oral Liquid by HPLC.Methods The determination was carried out on a Diamonsil C18 column,with mobile phase of acetonitrile-water(29∶71) at room temperature.The flow rate was 1.0mL?min-1 and the detective wavelength at 277 nm.Results The calibration curves was linear in the range of 0.068～ 0.340 ? g(r=0.9996).The average recovery rate of tested sample was 99.7 %(RSD=2.1 %).Conclusion The method was specific,accurate and precise.It can be used for the quality control of Baohe Oral Liquid.
RESUMO
Objective To determine the content of anabasine in Fengshiding tablets.Methods RP-HPLC method was established.Diamonsil-C18 was used as chromatographic column,the mobile phase consisted of methanol and 0.1 %triethylamine(5 ∶95,adjust pH to 3.6 with H3PO4),the flow rate was 1.0 mL?min-1 and the detection wavelength at 259 nm.Results The average recovery for Anabasine was 99.0 %,RSD=2.8 %(n=6).Conclusion The method can be used to determine the content of anabasine in Fengshiding tablets.
