ANALYTICAL STUDY ON PHYTOCHEMICAL AND ANTIMICROBIAL SCREENING OF SOLANUM NIGRUM IN VITRO

Abstract

Solanum nigrum(Black Nightshade) is a medicinal plant member of the Solanaceae family of plants. This family comprises many genera, well known for their therapeutic properties. In addition to S. nigrum, this family includes fruits and vegetables such as potato (Solanum tuberosum), tomato, peppers, ornamental plants such as petunia, and other medicinal plants¹.The present work is focused on the phytochemical analysis and of aqueous, methanolic and hexane extracts of Solanum nigrum. And screening for there antimicrobial activity against Staphylococcus aureus and Candida albicans by well diffusion method measuring the zone of inhibition by turbidity method. This study assures that methanol is the best available solvent for phytochemical extraction and also it confirms the antimicrobial activity of the plant extract.
