Vernonia amygdalina is a plant species that contains alkaloids as a primary phytochemical constituent, as confirmed by qualitative screening [1], [2], [3] and quantitative measurements of its leaf extracts [4], [5], [6], [7]. These alkaloids contribute to the plant's biological properties [8], [9] and its characteristic bitter taste [10].
