ABSTRACT
Phytophenols are widely distributed in the vegetable kingdom. This is the reason why, for the first time, we evaluate the phenolic compound content and the antioxidant profile Heterotis rotundifolia alcoholic tinctures, a therapeutic plant species from Côte d’Ivoire. The study takes into account the extraction, the total phenol quantification and flavonoid contents as well as that of the antioxidant activity vis-a-vis the stable radical DPPH by the median effective concentration (EC50). The decoction provides the best yields of extracts. Overall, alcoholic tinctures showed variable total phenol and flavonoid contents and notable antioxidant profiles. The results obtained allow affirming that Heterotis rotundifolia is an antioxidant plant.
Keywords: Heterotis rotundifolia, phytochemistry, antioxidant activity, EC50.
