Halacsya sendtneri (Boiss.) Dorfl.- Antioxidant activity of the methanol extract

Abstract

Halacsya sendtneri is a only species currently described of the genus Halacsya of the family Boraginaceae.This perennial tufted plant with a stout and long rootstock is an obligatorz serpentinophzte and grows on open serpentine rocks, along stone blocks at the altitude between 190/1500m. Characteristic species of the endemic communitz in West Serbia Halacsya sendtneri-Potentilla mollis. H. sendtneri is considered a Tertiary relict and endemic species in the central Balkan, particularly in Serbia, Bosnia-Herzegovina, and Albania. There are no data of the possible antioxidant activity of the methanol extract of Halacsya sendtneri by using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging assay. Free radical scavenging activity (expressed as IC50 - concentration which decrease absorption of DPPH for 50%) of methanol extract was IC50 - 0,0480 mg/ml. The results showed that the methanol extract of Halacsya sendtneri have antioxidant effect, and may provide protection on free radicals, so it could be considered as a new source of natural antioxidant.
