Synthesis of Flavonoids Derivatives using Polar and Non-Polar Extract of Red Onion Skin (Quercetin) with Cashew Nut Shell Liquid

Red Onion skin extract and Cashew nut shell liquid has been considered as one of the best antioxidant anti-inflammatory precursors, it contains various polyphenols important flavonoids. In this research, flavonoid derivatives were successfully synthesized from polar non-polar red onion skin, cashew a combination extracts liquid. process, crude was obtained using potassium carbonate via maceration process acetone soxhlet extraction. extracted The synthesis carried out Williams ether 1,2-dibromoethane in presence base catalyst. FTIR products confirmed its modification. From result, can be concluded that performed better than extract. Hence for further studies, solvents should
