Phytochemical screening and nutritional potentials of the stems, leaves and flower of Allamanda cathartica were investigated. The phytochemical screening revealed the presence of tannins, flavonoids, saponins, terpenes, anthraquinones, cardiac glycosides and the absence of alkaloids in all three parts. Quantitative evaluation of the stems, leaves and flowers of Allamanda cathartica revealed moisture content (%) 1.50, 3.0, 1.0; Ash content (%) 2.0, 4, 0.5; protein (%) 1.50, 6.80, 2.50; Fats (%) 2.0, 3.0, 5; crude fibre (%) 24.0, 23.20, 22.0; carbohydrate (%) 72.0, 60.0, 69.0 respectively. The result of this study proves that Allamanda cathartica contains bioactive compounds that may be useful in nutrition and in the synthesis of various therapeutic drugs, and also suggests the popular use of Allamanda cathartica in herbal medicine.
