Total Phenolic Content and Free Radical Scavenging Activity of Malva parviflora L. (Malvaceae)

A.J. Afolayan, O.M. Aboyade and M.O. Sofidiya

Abstract: The free radical scavenging activity of the methanolic extract of Malva parviflora L. was examined using spectroscopic method against 2, 2-diphenyl-1-picrylhydrazyl radical (DPPH^•), radical cation ABTS^•+(2, 2`-azinobis [3-ethylbenzothiazoline-6-sulfonic acid] diammonium salt) and the ferric reducing agent. Total phenolic, flavonoid and proanthocyanidin contents were also determined to assess their effects on the antioxidant activity of the extract. The results showed that the methanol extract of M. parviflora differed in its capacity to quench or inhibit DPPH^• and ABTS^•+. The extract showed a greater ability to quench ABTS^•+by inhibiting 94.3% of the radical cation while it inhibited 9.3% of DPPH^•. The free radical scavenging activities were compared using BHT and rutin as reference antioxidants. The plant possessed a higher flavonoid content than phenolics and proanthocyanidins and a positive linear correlation was established between these polyphenols and the free radical scavenging activities.
