The present study dealt with the hydro distillation of Nigella sativa seeds and GC-MS analysis. The total composition of the oil was 86.7%. The seed volatile oil was tested against 19 microbes (Gram positive, Gram negative and fungi), which showed that Gram negative bacteria Haemophilus influenza, Klebsiella pnemoniae, and Proteus vulgaris were highly sensitive against the antimicrobial agent, whereas the fungi such as Trichoderma vibriae,. Pencillium rubrum; and Dermatophyte: Trichophyton mentagrophytes; had no response at the 20µl concentration.
