Evaluation of total phenolic, flavenoeid content and antioxidant activity of Leaf and Fruit in 14 different genotypes of Ziziphus mauritiana L. in south of Iran

Medicinal plants uses and their active ingredients as natural anti microbial and antioxidant agents are interested recently, because they had high quality of flavonoid and terpenoid antioxidants get a great importance in the food and drug industries. In this research to purpose of phytochemical and antioxidant activity of Ziziphus mauritiana L. the leaves and fruit of 14 wild-growing genotypes of plant were collected in 2016 from the southern regions of Iran (Jiroft, Rodan, Minab and Jask). Plant hydro alcoholic extract was obtained by maceration technique. Total phenol and flavonoid content were measured by Folin-Ciocalteu reagent and Aluminium chloride method, respectively and antioxidant activity was evaluated by DPPH method.The results were showed that the highest total phenol content (20.41 mg GAE / g dry extract) and the flavonoids (52.12 mgQEE / g dry extract) was belong to plant genotype of Rodan region (two). According to data the leaf extract of plant had more total phenol content and antioxidant activity with IC50= 88.08 µg/ml than fruit extract of plant especially in Rodan region (two). The plant organ and the habitat condition could have a significant effect on the phytochemical content and antioxidant activity of plant extract. So due to high contents of phenol and flavonoid contents and optimal antioxidant activity of plant in Rodan and then Talar region respectively, Ziziphus mauritiana L. could be referred as an natural effective antioxidant get use a great importance in the food and drug industries.
