Abstract: The plant leaves contain a number of medicinally important compounds. The present study was carried out to identify the phytochemicals and evaluate antimicrobial activity of hexane extract of Sinapis alba seeds. The antimicrobial activity was determined by well diffusion method and tested against different pathogens of three bacteria and two funguses. Antimicrobial activty of 50, 100 and 150% Hexane extract of Sinapis alba (white mustard), has been evaluated against streptococcus pneumoniae, Aspergillus niger, Salmonella typhi, klebsiella pneumoniae, Trichophyton Violaceum. The seeds of hexane extract contain terpenoids and fattyacids. In 150% concentration Sinapis alba showed the highest 20mm antibacterial zone against streptococcus pneumoniae. In 100% and 150% concentration Sinapis alba showed the highest 15mm, 20mm, antimicrobial zone respectively against Aspergillus niger. The extract showed inhibitory effects due to the presence of terpenoids and terpenoids.
