Description

The antioxidant capacities, total phenolic and flavonoid content of five different extracts (Et2O, CHCl3, EtOAc, n-BuOH and H2O) of Calendula officinalis (L.) growing wild in Kosovo were analyzed. Total phenolic and flavonoid content were quantitatively determined to the Calendula officinalis (L.) growing wild in North-Western part of Kosovo in altitude levels (780 m). The amount of total phenolics in Calendula officinalis (L.) extracts ranged from 7.30 mg GAE/g d.e. to 37.60 mg GAE/g d.e.. The amount of total flavonoids in Calendula officinalis (L.) extracts ranged from 10.15 mg RE/g d.e. to 27.52 mg GAE/g d.e. Free radical scavenging capacity (RSC) was evaluated by measuring the scavenging capacity of extracts on DPPH. EtOAc and H2O extracts of Calendula officinalis (L.) expressed very strong scavenger activity. On the other hand, Et2O and CHCl3 extracts showed much weaker effect in the neutralization of DPPH. The observed differences in antioxidant activity could be partially explained by the levels of phenolics and flavonoids in extracts of Calendula officinalis (L.).Based on these results, this plant can be used to discover bioactive natural products that may serve as leads in the development of new additives for application in Food technology.
