Proximate composition, nutritional evaluation and functional properties of a promising food: Arabian wax Cissus ( Forssk) leaves.

is a wild plant, extensively used during scarcity and famine; however, the information about its chemical and nutritional properties still limited. In this work, was evaluated for its chemical, nutritional and functional properties. The results revealed that mainly contained carbohydrates (72.54%), proteins (12.16%), ash (12.53%), dietary fiber (14.10%), in addition to adequate amounts of essential amino acids and minerals. Fructose, glucose, galactose, and arabinose were the major monosaccharides with a percentage of 23.32, 13.60, 1.24, and 0.25 g/100 g DW, respectively. Furthermore, it was found that contained important vitamins, including thiamin (5.37 mg/100 g DW), riboflavin (1.19 mg/100 g DW), pyridoxine (0.46 mg/100 g DW) and folic acid (0.20 mg/100 g DW). The findings of functional properties revealed good water and oil absorption capacities of 2.74 and 1.63 g/g, respectively. Foaming capacity and water solubility index were 14 and 18.74%, respectively. From these results, it can be stated that has high nutritional values, which could be used widely in food applications.
