%X The objectives of this study were to analyze the lipid content of 10 oil seeds of different plant families and the antimicrobial activities of these plant seeds that can add a new dimension in the alternative medicinal field of Indian origin. Chemical analysis reveals that the major components of all the seeds were myristic acid, ricinoleic acid, linoleic acid, palmitic acid, lauric acid and oleic acid. The other 4 components i.e., linolenic acid, palmitoleic acid, steric acid and arachidic acid present less than 30% of plant seeds. The primary screening tests for antibacterial and antifungal activities were shown positive for all the compounds. Escherichia coli and Candida albicans has shown a zone of clearance ranging 11-15 mm whereas Pseudomonas aeroginosa, Salmonella typhi, Staphylococcus aureus, Aspergillus niger and Penicillium notatum showed the range between 16-20 mm. It is assumed that oxidative effect could plausibly play an important role in the antimicrobial function of fatty acids. The higher oil content were found to be on Aegle marmelos (49%), Prunus amygdalus (48%), Cardiospermum halicacabum (47%), Brassica alba (38%) and can suggest as an agent of conservation in the cosmetic and/or food industries, as an active compound in medical preparations and as a disinfectants.
