slugEffects of Extraction Techniques on Total Flavonoids, Phenols and Antioxidant Activity of Different Plants Extract
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 1
Abstract
Among the known fruits and vegetables, darkcoloured fruits and vegetables have been reported to be good sources of phenolics, including flavonoids, anthocyanins and carotenoids and are recognized as more healthy to human body. The plants (such as Mentha, Zingiber officinale , Allium cepa and Prunus) were extracted by two methods i.e. ultrasonicator and solvent extractor, These plants were determined for moisture content and the extracts were analyzed for total phenolic content (TPC), total flavonoids (TFC) and antioxidant activity (DPPH radical scave nging assay ) . The results showed that, there was significant difference ( P<0.05) in TPC, TFC and antioxidant activity for Mentha , Zingiber officinale , Allium cepa and Prunus . A significant and positive correlation found between TPC and DPPH activity using ultrasonicator (r 2 =0.75) and solvent extractor (r 2 = 0.80) . TFC also showed a positive correlation with antioxidant activity as rutin standard (r 2 = 0.86) and (r 2 =0.88) for ultrasonicator and solvent extractor for various plants extracts. This indicated that phenolic compounds including flavonoids were the main contributors of antioxidant activity in plants extracts .
