Antioxidant Capacity, Total Phenols, Total Flavonoids and Colour Component of Cornelian Cherry (Cornus mas L.) Wild Genotypes

摘要

A number of selected cornelian cherry wild genotypes were investigated regarding antioxidant capacity, total phenols, total flavonoids and colour component. The total phenolic, total flavonoids and antioxidant activity of methanol extract of cornelian cherry fruits were determined using Folin-Ciocalteu, colorimetric and DPPH methods, respectively. Total phenolic content ranged from 163.69 (S1) to 359.28 (H2) mg GAE 100 gsup-1/sup FW. Genotypes H2 and H3 had the highest total phenolic content (359.28 and 343.50 mg GAE 100 gsup-1/sup FW, respectively), total flavonoids (54.26 and 64.48 mg QE 100 gsup-1/sup FW, respectively) and antioxidant capacity (2.39 and 2.71 mmolTrolox100gsup-1/sup FW, respectively). Significant differences of yellow/blue color component (b*), red/ green (a*) color component, values of lightness (L*) and chroma ? were obtained for extracts from fruits. The present study shows the potential of certain cornelian cherry genotypes as valuable source of natural antioxidants and gene stock for breeding programs.
