Total Phenolic and Flavonoid Content, Antioxidant Activity of Ficaria Verna

Abstract

The objective of the present study was to determine the total content of phenolics and flavonoids in ethanol extracts of a plant from the family of Ranunculaceae – Ficaria verna. Harvesting of medicinal plant was carried out in ecologically clean regions of west Ukraine in spring 2020. The extracts were obtained by maceration of grass, leaves,and flowers to compare the content of active substances in different types of raw materials. The total phenolic content was estimated spectrophotometrically using Folin Ciocalteu method. The total flavonoid content was measured by aluminium chloride colorimetric assay. The maximum content of phenolic and flavonoids compounds was observed in the grass Ficaria verna. The antioxidant effects of the extracts were investigated. The Ficaria verna can be regarded as a promising natural plant source of antioxidant effects with a high potential for phytopreparations.
