- Abstract
Based on the high performance liquid phase method for the determination of furanone, a method for the determination of polyfuran (pentahydroxymethylfurfural, furfural, acetylfuran, furanone, pentamethylfurfural) was established.The column was an Ultimate XB-C 18 column(250 mm×4.6 mm, 5 μm)with a column temperature of 35 °C, an injection volume of 10 μL, a wavelength of 285 nm, and a flow rate of 0.8 mL/min. Dewashing gradient conditions: 0-2 min, methanol-0.5 % formic acid (15 : 85,volume ratio);2 min-24 min, methanol -0.5 % formic acid (50 : 50,volume ratio);24 min-27 min,methanol -0.5 % formic acid (100 : 0, volume ratio);27 min-29 min,methanol -0.5 % formic acid(100 : 0,volume ratio);29 min-33 min, methanol -0.5 % formic acid(15 : 85, volume ratio). The recovery rates of pentahydroxymethylfurfural,furfural,furanone, acetylfuran and pentamethylfurfural were measured:97.8 %-99.6 %,95.4 %-97.3 %,96.3 %-97.2 %,95.3 %- 98.3 %,94.3 %-97.9 %,The coefficient of variation was 3.3 %,4.3 %,0.89 %,5.3 %,1.4 %.The five furan substances (pentahydroxydroxymethyl -furfural, furfural,acetylfuran, furanone, pentamethylfurfural) were suitable for detection.
