The objective of this study was to determine Antimicrobial activity of methanolic extract of cactus seeds powder against (Salmonella, Escherichia coli, Bacillus subtilis, Bacillus cereus, yeast and mycotoxins metabolites).Prickly pear seed Opuntia ficus-indica (L.) was analyzed for its chemical and nutritional content. The analysis included those for: moisture, crude lipid, crude protein, ash, and crude fiber, phenols, antioxidants, saponine, flavonoids) and mineral contents (Fe, Cu, Zn and Se).Results illustrated that, mannan and β- glucan, content 153.44 and 69.20 g / Kg, respectively. Minerals determined of Fe, Zn, Cu and Se were: 127.20, 152.90 and 1.29 mg/kg and 24.76 ppb, respectively.Linoleic acid was established as the major fatty acid (54.03%), followed by oleic (22.41%) and palmitic (17.11%) acids. Both docosahexaenoic (DH) and docosenoic acids were detected in prickly pear seed oil in low amounts. It could be concluded that, prickly pear seeds powder are an important source of natural fiber and, given its high linoleic acid content, its oil can be used as a nutraceutical agent.
Key words: Nutritional composition, prickly pear (Opunti aficus-indica (L.) seeds, fatty acids, fiber, minerals, protein, amino acids, antimicrobial activity.
