Abstract

Food processing waste as Citrus sinus peel is a type of agricultural waste that causes a great environmental problem. The problem could be solved by using this waste for production of valuable chemicals and pharmaceuticals. In this study three flavonoidal compounds were isolated from Citrus sinus peel. The isolated compounds were identified as nobeletin, sinensetin and isosinensetin using 13C-NMR and 1H-NMR techniques, in addition to melting point determination.. These compounds have various reported pharmacological activity.
