. The physicochemical properties, fatty acids profile, antimicrobial activity and soap potential of the seed oil of Prosopis africana were examined. The prepared natural antiseptic soap was absolutely devoid of all forms of synthetics such as alkaline, antimicrobial agents, preservatives, colourants and fragrances. The seed had an oil yield of 4.98% while the saponification, acid, free fatty-acids and iodine values were found to be 11.60 ± 0.54 mgKOH/g, 16.96 ± 0.57 mgKOH/g, 14.60 ± 0.45% oleic and 145.47 ± 0.66 I2 100 g-1 of the oil respectively. The GC-MS result of the prepared fatty acid methyl ester (FAMEs) indicated the presence of oleic acid (33.67%), a monounsaturated fatty acid as the most prominent fatty acid in the oil, followed linoleic acid (18:2), a polyunsaturated acid making up 31.92% of the oil. Palmitic acid (24.96%) is the most abundant saturated fatty acid while stearic acid and valeric acid makes up (7.3%) and (1.96%) respectively. The antimicrobial activity of the oil tested against ten strains of organisms which include: Streptococcus aureus, Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, Salmonella typhi, Klebsiella pneumoniae, Candida albicans, Penicillium notatum, Rhijoptius stoloniter and Aspergillus niger showed good activity. The Minimum Inhibition Concentration (MIC) values obtained for the oils ranges from 31.25 to 125 mg/mL against all the test organisms and within the range 0.125- 0.5 mg/mL for the prepared soap. The physicochemical analysis of the P. africana soap was comparable to commercial antiseptic soaps. The result indicated that quality renewable natural antiseptic soaps ccould be obtained from P. africana seed oil. The result confirms that soaps made from natural lye (alkaline solution) has the capacity to replace existing commercial antiseptic soaps made of synthetic sodium or potassium hydroxides, antimicrobial agents, artificial preservatives and colourants which partly accounts for environmental pollution, increase in antimicrobial resistance and endocrine disruption. The adoption of this green antiseptic soap synthesis technique utilising underexplored P. africana seed oil can help mitigate the negative environmental impact of non-biodegradable synthetic reagents. Resumen. Se examinaron las propiedades fisicoquimicas, el perfil de acidos grasos, la actividad antimicrobiana y el potencial de jabon de la semilla de aceite de Prosopis africana. El jabon antiseptico natural preparado carecia absolutamente de todas las formas de sinteticos tales como agentes alcalinos, antimicrobianos, conservantes, colorantes y fragancias. La semilla tuvo un rendimiento de aceite de 4.98%, mientras que los valores de saponificacion, acido, acidos grasos libres y yodo fueron 11.60 ± 0.54 mgKOH / g, 16.96 ± 0.57 mgKOH / g, 14.60 ± 0.45% oleico y 145.47 ± 0.66 I2 100 g-1 del aceite respectivamente. El resultado de GC-MS del metil ester de acido graso preparado (FAME) indico la presencia de acido oleico (33,67%), un acido graso monoinsaturado como el acido graso mas prominente en el aceite, seguido del acido linoleico (18: 2), Acido poliinsaturado que constituye el 31,92% del aceite. El acido palmitico (24,96%) es el acido graso saturado mas abundante, mientras que el acido estearico y el acido valerico constituyen (7,3%) y (1,96%) respectivamente. La actividad antimicrobiana del aceite analizada contra diez cepas de organismos que incluyen: Streptococcus aureus, Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, Salmonella typhi, Klebsiella pneumoniae, Candida albicans, Penicillium notatum, Rhijoptius st. Los valores de Concentracion de inhibicion minima (CIM) obtenidos para los aceites varian de 31.25 a 125 mg / ml frente a todos los organismos de prueba y se encuentran dentro del rango de 0,125 a 0,5 mg / ml para el jabon preparado. El analisis fisicoquimico del jabon de P. africana fue comparable al de los jabones antisepticos comerciales. El resultado indico que se podrian obtener jabones antisepticos naturales renovables de calidad a partir del aceite de semilla de P. africana. El resultado confirma que los jabones hechos de lejia natural (solucion alcalina) tienen la capacidad de reemplazar los jabones antisepticos comerciales existentes hechos de hidroxidos de sodio o potasio sinteticos, agentes antimicrobianos, conservantes artificiales y colorantes que en parte representan la contaminacion ambiental, el aumento de la resistencia antimicrobiana y la endocrina. ruptura. La adopcion de esta tecnica de sintesis de jabon antiseptico verde que utiliza aceite de semilla de P. africana poco explorada puede ayudar a mitigar el impacto ambiental negativo de los reactivos sinteticos no biodegradables.
