Determination of Content of Rutin in Rose Flowers of Miaofeng Mountainin of Beijing by HPLC
Abstract:Objective:To determine the content of rutin in rose flowers of Miaofeng Mountain in Beijing by HPLC.Methods:The samples were extracted by ultrasonic,column chromatography of Agilent Zorbax SB-C18 (250 mm×4.6 mm,5 μm) was used in the study,the detection wavelength was 310 nm,the column temperature was 25 degrees,the mobile phase was 0.2% acetic acid acetonitrile (90∶10),elution rate was 0.8 mL·min-1.Results:The content of rutin in rose flowers of Miaofeng Mountain in Beijing was 1.254 9 mg·g-1.Conclusion:The method is simple,rapid,accurate and reproducible.So it is suitable for the determination of the content of rutin in rose flowers.
