Abstract:
Ten red wine samples from Helan Mountain in Ningxia were used as test materials.Simultaneous determination of 10 mono-phenols in wines by HPLC was studied.The results showed that chromatographic separation was performed by UltraⅡ-C18 precolumn (250 mm × 4.6 mm,5 μm).A gradient elution consisting of 〖JP〗solvent A (water∶acetic acid，98∶2，V/V) and solvent B (acetonitrile) was applied with flow rate at 1.0 mL?min-1 and detection wavelength at 280 nm.Under this chromatographic condition，the calibrations curves were linear with r>0.999 and recoveries of several mono-phenols>80%.The results showed that 10 mono-phenols were found in ten wines.Gallic acid and catechin content were higher than that of all the mono-phenols.
