Abstract: Objective To establish an HPLC method for the content determination of gallic acid and kaempferol-3-O-rutinoside inNymphaea candida Presl..MethodsThe separation was carried out on a Wondasil C18 column (250 mm×4.6 mm, 5μm). The mobile phase was methanol-0.1% acetic acid solution, with gradient elution;the flow rate was 1.0 mL/min;the detection wavelength was set at 270 nm;the column temperature was 30℃.Results The linear ranges of gallic acid and kaempferol-3-O-rutinoside were 0.065-0.585μg (r=0.999 1), 0.133-1.197μg (r=0.999 5), respectively. The average recoveries of gallic acid and kaempferol-3-O-rutinoside were 102.71%, 102.08%, with RSD of 1.97%, 0.46%, respectively.Conclusion This method was rapid, accurate, and reliable. It can be used for the determination of allic acid and kaempferol-3-O-rutinoside in Nymphaea candidaPresl..
