Chemical Characterization and Edibility of the Oil Extracted from Citrullus colocynthis Seeds

The characteristics and composition of the crude oil extracted from Citrullus colocynthis seeds were examined. Data obtained for the iodine value, saponification number, Reichert‐Meissl and others compare well with other edible oils. Thin‐layer chromatography in conjunction with gas‐liquid chromatography‐mass spectrometry revealed over 75% degree of unsaturation major among which were linoleic, 50.6% and oleic acids, 25%. Upon storage, the oil showed relatively low peroxide values that were within the acceptable limits set for other vegetable oils. Animal experimentation trials on the oil using chicks as the experimental animals did not show any toxicity effects. Based on these results, Citrullus colocynthis oil might be of some potential use for animal feed and/or human consumption.
