ABSTRACT
The medicinal benefits of herbs have been known for centuries: Herbs contain powerful ingredients that if used correctly, can help heal many body ailments. In this study, methanolic extracts of three common medicinal plants namely: Androngraphis paniculata (King of bitter), Vernonia Amygdalina (Bitter leaf) and Azadirachta indica (Nee,) were compared on the basis of nine phytochemicals: Alkaloids, Flavonoids, Tennis, Saponins, Anthraquinones, phenols, Phlobatanins, Cardiac glycosides and Cardenolides. The occurrence rating of each phytochemical in each of the medicinal plants were categorized into four: absent (-), low (+), moderate (++), and high (+++). All the phytochemicals were generally low in Andrographis paniculata compared, especially with Azadirachta indica plant in which high values were recorded for Tannins, saponins and Anthraquinones. Unlike in the Andrographis paniculata where the occurrence were either absent or low, Vernonia amygdalina showed a moderate to high rating for four of the nine phytochemicals and therefore ranked to be lower in phytochemical content relative to the Azadirachta indica extract, but higher than those of the Andrographis paniculata. These differences were observed in the phytochemical analysis which attributed to the bitter taste and medicinal properties of these plants.
