Objective: To establish an HPLC method for the determination of loganic acid
gentiopicroside
swertiamarin
sweroside
shanzhiside methylester in Gentiana straminea. Method: The assay was performed on a Diamonsil C18 column (4.6 mm× 250 mm
5 μm) eluted with acetonitrile-0.05% phosphoric. The detection wavelength was 240 nm
the flow rate was 1.0 mL·min-1
and the column temperature was set at 30 ℃. Result: The calibration curves were linear in the ranges of 0.042 1-8.420 0 μg(r=0.999 7) for loganic acid
0.094 2-18.830 0 μg(r=1.000 0) for gentiopicroside
0.012 4-2.471 2 μg(r=0.999 9) for swertiamarin
0.009 9-1.971 2 μg (r=1.000 0) for sweroside
0.011 3-2.260 0 μg(r=0.999 0) for shanzhiside methylester. The average recoveries were 95.39%-103.75%(RSD≤2.6%). Conclusion: The method is simple and accurate for the quality control of G. straminea Radix.
