摘要：
The proximate, physicochemical, and fatty acid compositions of seed oil extracted from khat (Catha edulis) were determined. The oil, moisture, crude protein, crude fiber, crude carbohydrate, and ash content in seeds were 35.54, 6.63, 24, 1.01, 30.4 %, and 1.32 g/100 g DW respectively. The free fatty acids, peroxide value, saponification value, and iodine value were 2.98 %, 12.65 meq O-2/kg, 190.60 mg KOH/g, and 145 g/100 g oil, respectively. Linolenic acid (C-18:3, 50.80 %) and oleic (C-18:1, 16.96 %) along with palmitic acid (C-16:0, 14.60 %) were the dominant fatty acids. The seed oil of khat can be used in industry for the preparation of liquid soaps and shampoos. Furthermore, high levels of unsaturated fatty acids make it an important source of nutrition especially as an animal product substitute for omega-3 fatty acids owing to the high content of linolenic acid.
