Insufficient Antifungal Potential of Crude Extracts of Carissa Carandas Linn. & Nerium Oleander Linn.”

Objective : To evaluate the antifungal potential of crude extracts from different parts of Carissa carandas Linn. (Leaf, stem & root) and Nerium oleander Linn. (Leaf, stem & root). Material & method : Different parts of plants were collected, dried and then extracted by using soxhlet extraction method in different polar and non-polar solvents (Water, Methanol & petroleum ether). Extracts were then screened for antifungal activity using ‘Disc Diffusion Assay’ against Candida albicans (Yeast), Aspergillus flavus & Tricophyton mentagrophyte (fungi). Minimum inhibitory concentration, Minimum fungicidal concentration & Total activity were studied. Mean and Standard Deviation have also been calculated. Result :  The results indicate that all the tested extracts were found to have no antifungal activity against all the tested microorganisms. Conclusion : The tested extracts did not have, or had too little, antifungal activity. Hence, may not be explored as promising source of new antimicrobial drugs.
