Measuring of Antioxidant Capacity and Phytochemical Evaluation of Two Genotypes of Hawthorn from Maragheh Region

The antioxidant capability, total phenol, total flavonoid, anthocyanins, ascorbic acid contents, and reducing power contents of polar and non-polar extracts for two Genotypes of Hawthorn from Maragheh Region were evaluated in this work. The polar extraction of red type of Hawthorn had a higher total phenolic content as well as antioxidant the activity compared to that of the other subfractions. Antioxidant activities of the samples were determined by three various testing systems namely 2, 2-diphenyl-1-picrylhydrazyl (DPPH),1 β-carotene/linoleic acid and reducing power assay.2 In DPPH system, the highest radical scavenging activity was seen by the polar subfraction in of red type of methanol extract [44.05±4.52 (μg/ml)]. Our findings demonstrate that the methanolic extracts of two Genotypes of Hawthorn may be suggested as a new potential source of natural antioxidant.
