Bio-activity of oils of Trigonella foenum-graecum and Pongamia pinnata

Different concentration of oils obtained from two plants species belonging to family Fabaceae i.e. Trigonella foenum-graecum and Pongamia pinnata were evaluated for their antifungal and antibacterial activity against Aspergillus niger, A. fumigatus, Staphylococcus aureus and Pseudomonas aeruginosa by MIC determination and dry-weight method. Both the oils showed high degree of antimycotic and antibacterial activity. P. pinnata oil was more effective as compared to oil of T. foenum-gracecum. A. niger and S. aureus were more sensitive to oil of P. pinnata. Chemical analysis of oils performed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC-MS) showed the presence of fatty acids.
