ABSTRACT
Pawpaw (Carica papaya Linn) is a plant that grows wild in many parts of the tropics. C. papaya is well known for it’s exceptional nutritional and medicinal properties. The study was carried out to examine the yield of oil extracted from the dried seed of C.papaya by solvent extraction method. The Physicochemical properties and antimicrobial activities of the seed were assessed. The oil qualities are, specific gravity (0.81), refractive index (1.45), saponification value (109.46mgKOH/g), iodine value (50.06mgKOH/g), peroxide value (3.02mgKOH/g), Acid value (4.10mgKOH/g) and moisture content (0.11%). It showed antibacterial activities more on gram +ve bacterial than gram -ve bacterial with Staphylococcus aureus being most susceptible to the seed oil. It showed little to no activities on the fungi isolate except Asperagillus niger which was more susceptible the seed oil. The zone of inhibition of the Extract ranges from 10mm-25mm for bacteria isolates which shows sensitivity and 0mm-11mm for fungal which indicates it resistance to the extract. Thus it can be concluded that the seed can be utilized for extraction of oil which have various health benefits in respect to the antimicrobial agents present and its ability, to be a non drying oil and edibility due to the Physicochemical properties.
