UDK: 547.56:582.711.714(234.422 Trebević) Methanolic and acidified methanolic extracts of C. monogyna and C. rhipidophylla dried fruits were used in estimation of total phenolic contents and antioxidant activities. The extracts of fruit were examined for their antioxidant activity by DPPH method. Antioxidant activity of the extracts varied from 17.65 to 22.05 mg ascorbic acid equivalents per g-1 dry weight. Total phenols, flavonoids, monomeric anthocyanins and proanthocyanidins in fruits ranged from 21.53 to 34.72 mg gallic acid equivalents per g-1 dry weight, 0.75 to 1.92 mg rutin equivalents and 0.13-0.93 mg quercetin equivalents per g-1 dry weight, 0.51 to 0.82 mg cyanidin-3- glucoside equivalents per g-1 dry weight, 11.27-18.77 mg cyanidin chloride equivalents per g-1 dry weight respectively. The higher values of total flavonoids generally are obtained with 80% methanol extracts for both species. The amounts of all investigated compounds and antioxidant activity were significantly higher in C. monogyna fruits which were confirmed by one-way ANOVA analysis. Correlations between antioxidant activity and total phenols and proanthocyanidin contents were found as the main compounds influencing the antioxidant capacity of the samples. Obtained results suggest that both species represent valuable source of antioxidant compounds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
