ivAbstractIn this study, in vitroevaluation ofantioxidant activity, total phenolic content, and total flavonoids content of three different extracts of leaves and fruits (99% ethanol, 80% ethanol, and distilled water) of Ziziphus Spina-Christi, from three different geographical regions of West Bank (Al-Zbedat in the north, Jericho in the middle, and Bani Naeem in the south)were the leaves collected in April and the fruits were collected in May.The extracts of leaves and fruits were evaluated for their total phenolic content (TPC)using Folin-Ciocalteumethod, total flavonoids content (TFC) using Aluminium chloride method, and antioxidant activity which wasdetermined byfour different methods:1,1-diphenyl-2-picryl-hydrazyl (DPPH)free radicalscavenging activity, Ferric reducing antioxidant power (FRAP), Cupric reducing antioxidant power(CUPRAC), and free radical scavenging activity using ABTS. Allthe analyzes weremade with the use of UV-Visible spectrophotometer.Overall the Ziziphus Spina-Christi leaves and fruits showedstrong antioxidant ability and high phenolic content. The total phenolic content(TPC)in leavescollectedin Aprilin two seasonswereranged between273.4 (North, D.water) to 94.1(South, 99% Ethanol)mg of GAE/g DW,and 448(North, 80% Ethanol) to 301.5(Middle, 99%Ethanol)mg of GAE/g DW, respectively.Total phenoliccontent in fruitscollectedin Mayin two seasonswere ranged between 421.7 (middle, 99% Ethanol) to 58.5 (North, 99%Ethanol) mg of GAE/g DW, and 339.8 (North, 99% Ethanol) to 90.6(North, D.water) mg of GAE/g DW, respectively.The total flavonoids content(TFC)in leavescollectedin Aprilin two seasonswere ranged between 118.7 (Middle, 80% Ethanol) to 9.1 (Middle, 99% Ethanol)mg CE/g DW, and 39.6 (North, 80% Ethanol)to 10.5 (Middle, 99% Ethanol) mg CE/g DW, respectively. Total flavonoids content in fruitscollectedin Mayin two seasonswere ranged between 11.2 (Middle, D.water) to 2.5 (South, 99% Ethanol) mg CA/g DW, and 16.7 (North, 80% Ethanol) to 4.5 (South, 99% Ethanol) mg CE/g DW, respectively.Antioxidant activity using FRAP assay in leavescollectedin Aprilin two seasonswere ranged between 11.9 to 2.6 and13.6 to 7.4 mg Trolox/g DW, respectively, and vforfruits were ranged between 11.2 to 1.3 and21.1 to 3.1 mg Trolox/g DW, respectively. CUPRAC assay in leaves collected in Aprilwereranged between 124.5 to35.6 and 139.8 to 91.1 mg Trolox/g DW, and forfruitscollectedin Mayin two reasonswere ranged between 155.2 to 12.7 and 261.7 to 27.6 mg Trolox/g DW, respectively. DPPH assayin leaves collected in Aprilwereranged between 84.5 to 32.4 and134 to 67.4 mg Trolox/g DW, respectively, and for fruits were ranged between 87.3 to 28.1 and 141.7 to 29.3 mg Trolox/g DW, respectively. APTS assay in leavescollectedin Aprilin two seasonswere ranged between 2.89 to 1.3 and2.7 to 2.07 mg Trolox/g DW, respectively, and for fruits were ranged between2.9 to 1.6 and 2.27 to 1.53 mg Trolox /g DW, respectively.This study indicates that the leaves and fruits of Ziziphus Spina-Christi is a good natural source of phenolic content, flavonoids content, and antioxidant content.it seems that the antioxidant content and phenolic content in leaves is higher thanthatin fruits.
