Abstract

Phytochemical constituents, such as total phenol, allicin and pyrovic acid as well as antioxidant activity of thirteen ecotypes of Allium hirtifolium from different regions of Iran were evaluated. Average contents of total phenol, allicin and pyrovic acid per g fresh weight were 0.647 mg gallic acid equivalent (GAE), 2.127 mg and 84.412 µmol, respectively and antioxidant activity was 63.717%. The bulb extracts that exhibited statistically greater contents of studied phytochemicals consequently possessed higher antioxidant activities. Correlation analysis showed the accumulation of A. hirtifolium phytochemicals was associated with different mean annual temperatures and precipitation so it can be concluded that the genetic factors as well as environmental factors affected the antioxidant capacity of A. hirtifolium ecotypes. According to obtained results the ecotypes of Isfahan, Saral, Khorramabad showed the highest phytochemical compounds and antioxidant activity that can suggest as primary plant materials for breeding programs of this plant.
