简介
Indian grape wines are analyzed for total phenolic content and antioxidant activity along with other parameters, such as pH, alcohol content, and reducing sugars. Concentration of polyphenols, like tannic acid, catechol, vanillin, caeffic acid, ferullic acid, and resveratrol, was quantified using reverse phase-high performance liquid chromatography and ultra high performance liquid chromatography. The red wines showed the highest concentration of phenolic content (6.5 ± 0.1 mg/ml) and antioxidant activity (84.60 ± 1%) as compared to white and port wines, while red wine R2 showed the highest radical scavenging activity among red wines and R4 showed the lowest total phenolic content. The white wine W3 showed less total phenolic content and antioxidant activity. Further, a positive correlation between phenolic content and antioxidant activity was observed.
