Ageratum conyzoides has been utilized by herbal medicine practitioners in Eastern Nigeria intreatment and management of several disorders, such as; diabetes, inflammations, spasm, headaches, cancers, among others. The basis of these applications has not been well investigated. This present research studied the phytochemical, proximate, mineral and vitamin composition of leaves and roots of the plant. The chemical analyses were done according to standard procedures. Alkaloids, flavonoids, saponins, tannins, cardiac glycosides and anthraquinones were detected in both samples, while terpenoids were present in the leaves only. The values of these phytochemicals in the leaves were significantly higher (P<0.05) than those in the roots. Proximate analysis indicated that the leaves contain edash (12.64%), crude fat (2.27%), fiber (23.50%), moisture (10.02%), crude protein (14.73%) andcarbohydrate (36.84%), while ash (16.95%), crude fat (2.01%), fiber (26.74%), moisture (13.35%), crude protein (9.89%) and carbohydrate (31.06%) were found in the roots. Na, K, Ca, Mg, P, Zn, Mn and Fe were present in the leaves and roots, and their concentrations in roots were significantly higher (P<0.05) than in leaves. Both samples were found to contain vitamins B2, B6, C, E, thiamin and niacin. Their values in the leaves did not differ significantly (P> 0.05) from those in roots. These chemical constituents of leaves and roots of Ageratum conyzoides may be responsible their applications in treatment and management of various disorders.
