【Abstract】 Objective:A HPLC method is established to determine the content of trigonelline in Trigonella foenum-graecum .Method:The medicinal material was extracted by petholeum ether-ethanol. Asahipak NH 2P-50 column was used,mobilephase consisted of acetonitrile-water(75∶25) and detection wavelength was set at UV 265 nm.Result:The standard curve was linear in the range of 3.68～73.60 μg·mL -1 with the correlation coefficient of 0.9999. The average recovery rate and RSD were 97.4 %and 1.83%( n =6) respectively.Conclusion:It provides scientific indexes for quality control of T. foenum-graecum .更多还原
