Objective: To establish a method for determination of specnuezhenide in Nuzhen granules. Method: Samples were analyzed on a Waters-C18 column (4.6 mm×250 mm
5 μm) using methanol-water (40: 60) as mobile phase. Flow rate was 1.0 mL·min-1 and examination wavelength was set at 224 nm. Result: Specnuezhenide showed a good linearity in the range of 0.306 25-0.918 75 μg
regression equation was Y=4×10-7X-1.51×10-2(r=0.999) and the average recovery was 98.00% (RSD 1.48%
n=6). Conclusion: The established methods are simple
accurate
reliable and can be used for the quality control of Nuzhen granules.
