The proximate composition of seeds, physicochemical characteristics, and fatty acid profiles of Ziziphus oenoplia seed oil were determined in this study. The seeds possessed low moisture (4.54%) and high carbohydrate (42.96%) and protein content (40%), making the seed oil suitable for storage and consumption. The saponification value (197.80) of the seed oil makes it a promising source for the soap and shampoo industry. The iodine and saponification values are comparable to those of major edible seed oils such as groundnut and soybean. The high amount of monounsaturated fatty acids (53.41%), especially oleic acid (53.38%), present in the oil makes it a better source for a low-fat diet and may reduce the risk of various heart-related diseases.

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 O2/kg, 190.60 mg KOH/g, and 145 g/100 g oil, respectively. Linolenic acid (C18:3, 50.80 %) and oleic (C18:1, 16.96 %) along with palmitic acid (C16:0, 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.
