Evaluation of Total Phenolic Content and Antioxidant Activity of Three Leaf Extracts of Ziziphus spina-christi (Sedr) Grown in Jordan

Aims: The primary aims of this study were to evaluate the total phenolic content and in vitro antioxidant activity of three different leaves extracts (methanolic, ethanolic and aqueous) of Ziziphus spins-christi grown in Jordan. Methods: Total phenolic content of the methanolic, ethanolic and aqueous extracts of the leaves of Ziziphus spins-christi was determined spectrometrically according to the Folin-Ciocalteu procedure. The antioxidant...
