The antioxidant activity of the honey was evaluated through the ferric reducing antioxidant power assay (FRAP) and the 1,1-diphenyl-2- picrylhydrazyl (DPPH) radical scavenging method. On the other hand, the antibacterial activity was assessed by the dilution technique to determine the minimum inhibitory concentration (MIC) of the honey against seven bacterial strains, including Gram-positive and Gram-negative bacteria. honey exhibits functional prop-...

Curcumin, a phytochemical from turmeric, and its derivatives have been extensively investigated from both chemical and biological strategies. However, the main problem encountered while using curcumin in clinical trials is its poor solubility and rapid degradation, resulting in its low levels in tissues, thus decreasing the medicinal effect of curcumin. Some studies showed that a metal-curcumin complex displayed potential medicinal...

PREPARATION OF SOME NEW SCHIFF BASES FROM 5-NITROVANILLIN. A series of Schiff bases were synthesized successfully based on the condensation reaction between 5-nitrovanillin and aromatic amines in moderate and high yields. The condensation underwent better in DCM solvent, acetic acid catalyst and anhydrous MgSO 4 as a drying agent and increased the yield up to 100 %.These new Schiff bases...
