| Abstract: | Objective To establish a method for determination of the content of Nootkatone in Fructus Alpinia oxyphyllae,and to determine the content of Nootkatone in Fructus Alpinia oxyphyllae from different places by this new method.Methods The Diamonsil-C_(18)(5 μm,250 mm×4.6 mm) column was used. The mobile phase was CH_3CN-H_2O(65:35) and the detection wavelength was set at 235 nm.The flow rate was 1.00 ml·min~(-1) and the column temperature was 40℃. Results The Nootkatone content showed a good linear relationship within the range of 0.115 2～0.268 8μg(r=0.999 9).The average recovery was 97.34% and RSD was 1.48%(n=6). The content of Nootkatone in Fructus Alpinia oxyphyllae from different places was within the range of 1.50～2.10 mg·g~(-1).Conclusion The method is simple and the result was reliable. It can be used for the quality control of this herbal medicine. |
