Physiochemical characterization of mango seed oil

Abstract

The purpose of the present study was to examine the physicochemical characteristics of mango seeds oil. Also using the extracted oil as antibiotic of some types of bacteria escherichiacoli , pseudomonas aeruginosa, staphylococcus aureus , bacillus subtilis and fungal , candida alibican. Results of extraction showed that the percentage of extracted oil from mango seeds by using soxhlet and n-hexane as solvent was found to be 12.48%. Analysis results of extracted oil by determined the physical and chemical properties showed that: The density,(0.8958g/cm3) at (25C0),refractive index ,(1.467) at (40 Co), viscosity, (14.18mpa.s),PH , (6.2), acid value, (2.805mg/g), saponification value, (190mg/g), peroxide value, (5), iodine value, (49.173g/100g), ester value, (187.195). Extracted oil was applied as antibiotic for some kinds of bacteria and fungi. The results obtained showed that the extracted oil did not give appositive results, where not lead to inhibition or killing of used bacteria. The oil was found to contain high levels of stearic acid (38.62%) followed by oleic (30.72%), palmatic(6.68%) and lenoleic (2.85%). Fourier transform infrared(FTIR) spectra showed the functional groups present in the oil. Many parameters of mango seed oil from Sudan are comparable to those of typical mango seeds oil reported in the literature. The physicochemical results and quality of mango seed oil from Sudan revealed that it could be employed for edible and commercial applications.
