PHARMACOGNOSTIC AND ANTIBACTERIAL STUDIES OF THE LEAF EXTRACTS OF SWARTZIA MADAGASCARIENSIS DESV (FABACEAE)

📄 Project Abstract

This study evaluated the pharmacognostic standards and antibacterial properties of the leaf extracts of Swartzia madagascariensis Desv (Fabaceae). This plant is widely distributed in Northern part of Nigeria; it has been exploited for both its medicinal and economic importance. It is used in the treatment of infections such as cutaneous wounds. Microscopic, chemo-microscopic, quantitative microscopic studies, qualitative and thin layer chromatographic studies, toxicity studies and antibacterial evaluation were carried out using standard methods. Microscopical studies revealed the presence of straight - walled anticlinal walls, polygonal epidermal cells, trichomes, anomocytic stomata on abaxial surface. The transverse section of the leaf through the lamina and midrib tissue was examined and revealed different anatomical features include: epidermal layers, palisade and spongy mesophyll cells, vascular bundles consisting of xylem and phloem vessels. Microscopy of the powder revealed fragm...
