Abstract:Objective To investigate the change rule of 5-hydroxymethyl furfural (5-HMF) in the processing of "Jiao Sanxian". Methods The samples of "Jiao Sanxian" were fired with different processing time and the contents of 5-HMF in each sample were detected by high performance liquid chromatography (HPLC). The HPLC analysis was performed on an Agilent C18, column (250 mm×4.6 mm, 5 μm) and the mobile phase consisted acetonitrile-water (8∶92), the detection wavelength was set at 283 nm. Results The linear range of 5-HMF was in the range of 0.2-64.0 μg/mL (r = 0.9997), average recovery was 99.74%, and RSD was 1.37%. The contents of 5-HMF were increased remarkably at the 8 min and 6 min for Fructus Crataegi and Fructus Hordei Germinatus, respectively, while it showed a steady pattern for medicated leaven. Conclusion "Jiao Sanxian" has a Maillard reaction in the processing, which produces common element 5-HMF. The contents of 5-HMF in Fructus Crataegi and Fructus Hordei Germinatus are increased obviously with the extension of processing time, while it is not obvious for medicated leaven.
