Antibacterial activity of some medicinal plants and seeds

ABSTRACT

Antibacterial activity of some medicinal plants and seeds were tested against Escherichia coli and Staphylococcus aureus. All water extracts of plants and seeds were found to be inactive except of Carum copticum [ajowain] which exhibited antibacterial activity against S. aureus. Homogenized seeds of Nigella sative [kalongi] and Carum compticum [ajowain] showed antibacterial activity against S. aureus. The results indicated that the active components of ajowain were partially soluable and that of kalongi were completely in soluble in water. Extraction of active components of both ajowain and kalongi was carried out using ethanol and acetone as solvents. Alcohol extracted oil of kalongi and acetone extracted oil of ajowain were active and prevented the growth of S. aureus
