Objective: To establish a HPLC method for determination of trigonelline in Baogan granulas. Method: The content of trigonelline was determined by HPLC. The Agilent ZORBA×NH2 column (4.6 mm×250 mm
5 μm) was used and mobile phase was composed of water-methanol-acetonitrile(20 : 40 : 40). The flow rate of mobile phase was 1 mL·min-1 and detection wavelength was at 265 nm and the column temperature was maintained at 40 ℃. Result: The linear response range was from 5-25 μL(r=0.999 9). The recovery rate was 98.3%(n=9)
RSD was 1.63%. Conclusion: HPLC method is simple
accurate and exclusive
which can provide the scientific basis for quality control of the Baogan granulas.
