Abstract
This work explores underutilized Lemon (Citrus limon) and Galgal (Citrus pseudolimon) residues for their phenolic contents and in-vitro antioxidant activities. Methanolic extracts from different parts of these two Citrus species were tested for total phenolic contents (TPC) total flavonoid contents (TFC) DPPH radical scavenging activity inhibition of linoleic acid peroxidation and reducing power by using respective in-vitro antioxidant model assays. The percentage yield of extracts total phenolic and flavonoid contents among parts tested varied from 6.13 “ 24.20 g/100g 98.20 “ 199.18 (mg gallic acid equivalent/g of extract) and 19.95 “ 39.60 (mg catechin equivalent/g of extract) respectively. Percent inhibition of linoleic acid peroxidation and DPPH radical scavenging capacity for the tested extracts ranged between 31-60 and 40-62 respectively. The overall order of antioxidant potential among parts of Citrus species was established to be: C. pseudolimon leave C. limon leave C. pseudolimon peel C. limon peel C. pseudolimon seed C. limon seed. It could be concluded that extracts of Citrus fruit residues especially leaves can be explored as an economically viable source of natural antioxidants and nutraceuticals.
