ABSTRACT
Objective To develop an HPLC method for the quantitative analysis of tricin in malt. Methods HPLC method was used. Analysis was performed on Spherigel C_ 18 column (150 mm?4.6 mm, 5 ?m) with acetonitrile-water-tetrahydrofuran-methanoic acid (26∶74∶10∶1) as mobile phase. The detection wavelength was 350 nm, flow rate was 1.0 mL/min, and the analysic volumn was set at 20 ?L. Results The calibration curve of tricin was linear in the range of 0.22-2.15 mg/L (r=0.999 8). The average recovery rate of tricin was 97.4% (RSD=1.7%) (n=9). Conclusion The method can be used to determine tricin in raw malt quantitatively.
