ABSTRACT
Objective To establish a method for the simultaneous content determination ofquercetin,kaempferol and pinocembrin in Penthorum Chinense Pursh.Methods The HPLC analysis was carried out on Alltima C18 (250 mm × 4.6 mm,5 μm) with a mixture of methanol-0.2% phosphate (45:55) as the mobile phase.The determination wavelength was set at 270 nm with the flow rate of 1.0 ml/min.The column temperature was set at 30 ℃.Results The quercetin,kaempferol and pinocembrin showed good linearity in the range of 0.316-10.120 μg (r=0.999 9),0.012-0.397 μg (r=0.999 6) and 0.063-2.016 μg (r=0.999 8) respectively.The average recovery rates of quercetin,kaempferol and pinocembrin were 99.34% (RSD=1.51%),99.76% (RSD=l.96%) and 98.34% (RSD=1.56%) respectively.Conclusions The method is accurate and sensitive,which can be used for the content determination of quercetin,kaempferol and pinocembrin in Penthorum Chinense Pursh.
