摘要:

采用化学模拟体系对青梅酒的总抗氧化能力、清除DPPH 自由基能力进行测定;并建立一种用XDB-C18柱(4.6mm × 250mm,5μm),以甲醇- 水溶液(25:75,V/V),流速1.0ml/min,检测波长202nm,柱温30℃条件下,用HPLC 测定Lyoniresinol 的方法。结果表明,青梅酒对DPPH 自由基清除能力IC50 为2.84%,总抗氧化能力(TAC)为(18.785 ± 0.722)mmol/ml(FARP 法),青梅酒中Lyoniresinol 含量为0.772mg/L。显示青梅酒具有较强的抗氧化能力。

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.
