ABSTRACT
[Aim]To establish an HPLC method for determination of geniposide in Jieyu'anshen Granule Liquid.[Methods]A shimpack C18 column was used.The mobile phase was Acetonirile-water(15:85).The detection wavelength was 238nm.[Results]The linear range of geniposide was 0.0375~0.2250ug,r=0.9999(n=6).The average recovery was 98.67%.[Conclusion]This method is convenient,rapid and accurate.It can be for quality control in Jieyu'anshen Granules Oral Liquid.
ABSTRACT
AIM:To develop the quality standard for Capsicum Rheumatism Gel(Fructus Capsici extract,menthol,borneol). METHODS:HPLC was used to determine capsaicin in Capsaicum Rheumatism Gel.The se-(paration) was performed on zorbax C_(18) column with methanol-water-phosphoric acid (70∶30∶0.085) as a mobile phase.The flow rate was 0.8 mL/min,and the detection wavelength was at 280 nm.Menthol and borneol contents in Capsaicum Rheumatiosm Gel were determined by GC and naphthalene was adopted as internal standard substance. RESULTS:There was a good linear relationship for capsaicin at a range of 0.082 65-0.578 55 ?g and the average revovery was 97.86% with RSD=1.28%.There were good liner relationships for menthol and borneol at a range of 0.081 0-1.053 ?g,0.080 8-1.050 4 ?g and the average revovery was 98.668%,97.536%. CONCLUSION:The method proves to be simple,precise and reproducible and is suitable for quantitative control of Capsicum Rheumatism Gel.
