Vernonia amygdalina is a plant species that contains saponins as a secondary metabolite, as confirmed by phytochemical screening [1] and chemical analysis [2]. These saponins contribute to the plant's bitter taste [3] and have been quantified in various leaf extracts {fact:4, fact:5, fact:6, fact:7}.
