1-Indanone chalcones and their 2,4-Dinitrophenylhydrazone derivatives: Synthesis, physicochemical properties and in vitro antibacterial activity

Chalcones are natural biocides. Several publications appear every year covering the synthesis of chalcones because they exhibit an array of pharmacological activities. In this study, some condensation reactions of 1-Indanone with substituted benzaldehydes were carried out under different reaction conditions. The chalcone products were converted to their corresponding 2,4-Dinitrophenylhydrazone derivatives and evaluated...

Determination of some heavy metals in selected edible vegetables grown along River Yedzaram in Uba area Adamawa State, Nigeria

The levels of some heavy metals were investigated in selected edible potions of the vegetables; Amarathus caudatus (Spinach) and Hibiscus sabdariffa (Rosella) are grown in Uba area along the Yedzaram River in North Eastern Adamawa State, Nigeria. All samples were randomly collected from two different gardens. The levels of the heavy metals, (Cu, Fe, Cd, Cr and Zn) were analyzed using Atomic Absorption Spectrophotometer...
