Abstract:

The total antioxidant capacity (TAC) and DPPH· scavenging activity of plum fermented wine were measured using chemical simulation system. A HPLC method was developed for the determination of content of lyoniresinol in plum fermented wine. The HPLC separation was preformed on a XDB-C18 (4.6 mm × 250 mm, 5 μm) at 30 ℃ using a mobile phase composed of a mixture of methanol and water (25:75, V/V) at a flow rate of 1.0 ml/min, and lyoniresinol was detected at 202 nm. The IC50 of scavenging DPPH· radicals was 2.84% and the TAC was measured as being (18.785 ± 0.722) mmol/ml by FARP method. The lyoniresinol content was 0.772 mg/L. In general plum fermented wine has stronger antioxidant activity.

Key words: plum fermented wine, antioxidation, lyoniresinol, DPPH radical, TAC
