Abstract
Abstract
Background
The antimicrobial activity against clinically and agriculturally important microorganisms, antioxidant property and chemical profiling of acetone crude extracts of non-edible oil-seed cakes of neem (Azadirachta indica A. Juss), madhuca (Madhuca longifolia syn. Madhuca indica Gmelin) and simarouba (Simarouba glauca DC) obtained by hot and cold extraction methods were tested in-vitro.
Results
The hot neem and cold acetone extracts of madhuca and simarouba were inhibitory to Staphylococcus aureus. The enteric pathogens-Enterococcus faecalis and Salmonella enterica were inhibited by both hot and cold extracts of simarouba cake. Fusarium oxysporum and Colletotrichum capsici were sensitive to oil-seed cake extracts of madhuca and simarouba cake extracts followed by neem cake extract. The Aspergillus flavus was highly sensitive to neem followed by madhuca and simarouba extracts. The cyclic voltammetry of all extracts indicated the presence of oxidation peaks at different Epa values suggesting the presence of antioxidant ability. The GC–MS profile revealed the presence of pharmacologically important essential compounds.
Conclusion
The study revealed the presence of bioactive compounds in non-edible oil-seed cakes that could be exploited for human welfare.
