Phytochemical Screening of Leaf Extracts of Eleven selected Tropical Plants Species from Eastern and Southern Nigeria

Abstract

The pyhtochemical constituents of butanol and acid leaf extracts of eleven (11) plant species from three different families (Annonaceae, Apocynaceae and Euphorbiaceae) obtained from various locations in eastern and southern Nigeria were made following standard techniques. Results obtained show that the leaf extracts contain alkaloids, flavonoids and saponins. This paper provides evidence that alcoholic and acid leaf extract of the selected plant species studied contains medicinally important metabolites that justifies their usage as traditional medicine for treatment of various ailments.Keywords: Tropical plants, Phytochemicals, Ethno-medicine, Extracts
