Türkiye’de doğal olarak yetişen P. ferulacea (L.) Lindl.’in metanol ve etanol ile hazırlanan meyve
Abstract
It was aimed to determine anioxidant activity, and amount of total phenolic and flavonoid compoundsof methanolic and ethanolic extracts of P. ferulaceae (L.) Lindl. fruits from Turkey. The fruits were collected attwo different times, in May and July 2014. The total phenolic content of the extracts determined according to theFolin-Ciocalteu Reactifi (FCR) method was calculated as mg Gallic acid equivalent (GAE) g-1 extract. The totalflavonoid content of the extracts was expressed as mg Quercetin (QE) g-1 extract. The percentage of antioxidantactivity of each samples was assessed by DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) free radical assay. Totalphenolic and flavonoid contents of the extracts were determined to range from 11.750 to 79.111 mg GAE g-1 extractand from 2.266 to 9.089 mg QE g-1 extract, respectively. According to the results of DPPH test, all fruit extractsexhibited a slightly antioxidant activity.
