Evaluation of Anti-Oxidant Capacity, Total Phenol, Metal, and Mineral Contents of Ziziphus lotus Plant Grown at Some Regions of AlGabal AlKhder, Libya

The Ziziphus plant is widely used in Libyan traditional medical treatment for many infections, it is classified as one of the important medicinal plants. Ziziphus plant growth in Libya in some regions and it is tolerant to the climate in these regions, in semi-desert and mountain regions around Al Gabal Al Khder locations. In this study, the Ziziphus plant was selected and collected from different places, the semi-desert at Marawa station and Mountain at (AlHaeiea station). The contents of total phenols and antioxidant capacity were determined. In addition to the levels of minerals (Sodium, potassium, and Calcium), the quantities of phosphorus and nitrogen were also estimated. The results recorded that the ziziphus plant of the studied areas contained important amounts of antioxidant values and they ranged between (1.21 -1.73 mg/g). Also, the total phenol contents ranged between (1.90 -2.87ppm). The concentrations of sodium, potassium, and calcium were fluctuated in the ranges of (10.7 -25.10), (35.4 -49) and (20.3-30 ppm), respectively. While the phosphorous and nitrogen ranged between (1.90– 3.45) and (0.14 – 0.26 ppm), respectively. The results of the study indicated that the ziziphus collected from the selected contains important levels of antioxidants, total phenols, and minerals.
