Study of the Physicochemical Properties of Silybum marianum Seed Oil

Proximate composition of Si/ybum marianurTt seeds showed Ihat the seeds have oil content (26.05 %), moisture content (4.48 %), ash content. (1.l}3 %), crude fibre (5.48 %), carbohydrates content (87.2 'Yo), total protein (23 'Yo), acid value (1.2 %), and saponification value (190.74). In physicochemical properties the iodine value is (108.8 gli 00 g), pero"ide value (16.17 meql kg), free fatty acid value (17.92 'Yo), anisidine value (1.8979), color I optical density (0.3413). Fatty acid composition of the oil reveals that linoleic acid·(64.4 'Yo) and oleic acid (26.38 'Yo) are the predominant unsaturated fatty acids-. The saturated fatty acids found in Si/ybum mananllln seed oil are palmitic acid (7.22 'Yo) and stear~ acid-(2.0 'Yo).
