Ziziphus spina-christi L. extract from the northern region of Saudi Arabia, was investigated to determine its chemical composition and evaluate antioxidant antifungal properties. Fresh leaves were extracted using Soxhlet apparatus yield 8% w/w. Results qualitative study showed that this is rich in compounds belonging several classes (saponins, phenols, tannins). GC-MS analysis detected 38 with ...

This study aims to investigate the cytotoxicity of Andrographis paniculata, Ziziphus spina-christi and Gymnanthemum extensum crude extracts their combination with low piperine fractional Piper nigrum extract. All plants were extracted water five organic solvents (methanol, ethanol, dichloromethane, ethyl acetate hexane). Cytotoxicity was assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tet...
