摘      要：A quantification and characterization study of oil from pumpkin seeds was carried out on three pumpkin varieties,namely,Japanese type of the Curcubita maxima species,Green Kabocha and butternut squash of the Cucurbita moschanta *** extraction was done using the Soxhlet method with petroleum ether as the *** physicochemical properties of acid value,iodine value,specific gravity and refractive index were *** results were analyzed statistically using one way ANOVA at a 5% level of *** mean values of oil content,acid value,iodine value,specific gravity and refractive index for Japanese type pumpkin were found to be 35.67%,2.24 mg KOH/g,26.45 mg I2/100 g,0.9126 and 1.47,*** Green Kabocha,the mean values of the above five properties were 30.12%,3.35 mg KOH/g,25.3 mg I2/100 g,0.9126 and 1.469,*** the Butternut squash type the mean values of the above five properties were 34.76%,3.74 mg KOH/g,26.61 mg I2,0.9131 and 1.471,*** can be noted that from the low acid values of the pumpkin oil,pumpkin oil can be identified as *** the low iodine value indicated that the pumpkin oil was *** addition,the low iodine value also suggested that the oil contains few unsaturated bonds and therefore has low susceptibility to oxidative *** a comparison of extraction rates from other oil sources in Uganda such as cotton(15%-20%),soybeans(19%-21%),the obtained results in this study suggested that pumpkin seeds are a viable source of vegetable oils that can be utilized for commercial vegetable oil extraction in Uganda.
