QUANTITATIVE DETERMINATION OF ANTIOXIDANT POTENTIAL OF ARTEMISIA PERSICA

Abstract

An experimental protocol was designed to investigate the total flavonoids, phenolics and antioxidant potential of methanol extract of Artemisia persica. For initial screening of antioxidant activity DPPH on TLC was employed. After the qualitative confirmation of antioxidant potential, spectroscopic measurements were made through DPPH assay. Free fatty acids (FFA), Peroxide values (PV) and Iodine values were monitored in refined, bleached and deodorized (RBD) sunflower oil. Plant extract was found to possess strong antioxidant potential in all mentioned assays. Total phenolic and flavonoid contents were 407 mg/g and 308 mg/g respectively.
