IN-VITRO ANTIMICROBIAL ACTIVITY OF EDIBLE OILS AGAINST HUMAN PATHOGENS CAUSING SKIN INFECTIONSAbstract
In recent years, a large number of oils and their constituents have been investigated for their antimicrobial properties against bacteria and fungi. The present investigation evaluated the antimicrobial potential of edible medicinal oils of Cocos nucifera, Helianthus annus, Brassica juncea, Ricinus communis, Arachis hypogea, Glycine max, Gossypium hirsutum and Sesamum indicum extracted from different solvents. There is a basis for the traditional use of these plants for local health remedies. Oils of these plants were screened for their antimicrobial activity against human pathogenic bacteria and fungi, causing skin diseases. The antimicrobial activity of these oils was investigated against Escherichia coli, Trichophyton rubrum and Candida albicans by agar well diffusion method, Helianthus annus seed oil showed maximum antimicrobial activity against tested bacteria and fungi with MIC values ranging from 0.62 to 40 mg/mL using inhibitory zone estimation. These results support the edible medicinal oils can be used to cure skin diseases.
