Total Phenolic and Flavonoids Contents, Radical Scavenging Activity and Green Synthesis of Silver Nanoparticles by Laurus nobilis L. Leaves Aqueous Extract
In this project, total phenolic and flavonoid contents of the aqueous extract of Laurus nobilis L. leaves were evaluated by colorimetric methods. These natural products which are found in plants extracts, can be considered as reducing and stabilizing agents in the synthesis of metal nanoparticles. Regarding to high amounts of these compounds in the extract, silver nanoparticles were synthesized...
متن کاملSnail shell as a natural and highly efficient catalyst for the synthesis of imidazole derivatives
A convenient, simple and green process for the synthesis of 2,4,5-triaryl-1H-imidazole and 1,2,4,5-tetraaryl-1H-imidazole derivatives using snail shell, which is abundant in Morocco, as a catalyst in ethanol at 40 °C has been developed. Additionally, short reaction times, excellent yields, simple procedure and relative non-toxicity of the catalyst are other noteworthy advantages and make this m...
