| Objective To establish a HPLC method for simultaneous determination of the content of myricitrin,isoquercitrin and luteolin in extract of Urena lobata L. Methods The HPLC analysis was carried out on Kromasiol-C18 column (4.6 mm×250 mm,5 μm) with acetonitrile-0.25% acetic acid solution (31:69) as the mobile phase for isocratic elution at a flow rate of 1 mL·min-1.The detection wavelength was 351 nm and the column temperature was 30 ℃. Results Good linear relationship were found in the the range of 6.97-278.80 mg·L-1 for myricitrin,7.29-291.50 mg·L-1 for isoquercitrin,2.96-118.40 mg·L-1 for luteolin.Their average recoveries were 98.39%,98.53% and 97.41%,respectively. Conclusion The method is accurate,reliable,and can be used for the quality control and evaluation of extract of Urena lobata L. |
