Study On The Mulberry Vinegar Antioxidation Effect

In this paper, the content of polyphenol in mulberry vinegar extract was measured.This study evaluated antioxidative activities of methanol extractant, ethanol extractant, acetone extractant and ethyl acetate extractant from mulberry vinegar in four kinds of antioxidative systems.The main results are listed as follows:1.The optimal conditions to identify polyphenol in mulberry vinegar as the follows,in room temperature,add some pattern solution; 1ml Folin-phenol developer; 5ml1mol/L sodium carbonate solution and constant volume to 10ml with distilled water,mix the solution and placed in black place for 1 hour,then identified using colorimentry method.2.The volume of polyphenol , rutin and T-AOC in four mulberry vinegar extracts were measured. The different extract has different totale antioxidant capacity and rutin number , that is methanol extractant > acetone extractant > ethanol extractant >ethyl acetate extractant ,and has different polyphenol number, that is methanol extractant >ethanol extractant >acetone extractant >ethyl acetate extractant.3.Polyphenol extracts in mulberry vinegar showed strong clear effect on super oxidized anionic radical,hydroxyl radical and lipid radical and DPPH radical. In methanol,ethanol,acetone and ethyl acetate extracts, methanol extract showed stongest clear effect on radical and ethyl acetate extract showed thinner clear effect on radical than other three extracts. Clear effect on super oxidized anionic radical,hydroxyl radical and DPPH radical of four extractions was stronger than BHT.4. Clear effect on super oxidized anionic radical and DPPH radical of mulberry vinegar was stronger than other vinegar.5. The volume of poly-phenol , rutin and T-AOC in mulberry vinegar and tea beverage,Kangshifu green tea,Wahaha green tea and apple vinegar beverage were measured. The different beverage has different totale antioxidant capacity,rutin and polyphenol number , that is mulberry vinegar and tea beverage was strongest than three beverage.6. Clear effect on super oxidized anionic radical and DPPH radical of mulberry vinegar and tea beverage was strongest than three beverage.7. Mulberry vinegar have certain influences for hot and shine stability ,after 40 days for hot and shine ,the mulberry red in mulberry vinegar has strong stability .
