Abstract	Due to the high nutritional value as well as the appreciated sensory characteristic Citrus crop is one of the most popular fruits over the world. Albedo and flavedo are commonly discarded as waste and could represent an important by-product of food industry. In a circular economy contest we carried out a characterization of albedo and flavedo of Citrus limon var pompia (pompia) followed by the evaluation of antioxidant potential and cytotoxic activity. The chemical analysis showed the presence of several functional ingredients such as the flavanones, naringin, neohesperidin, nereriocitrin and hesperidin while quinic acid resulted the main phenolic acid detected. The flavedo extract exerted a complete inhibition of the cholesterol oxidative process from 25 mu g of extract. Pompia extracts showed an inhibition of lipid oxidation in the beta-carotene-linoleate system with an activity equivalent to about 0.31% (albedo) and 0.34% (flavedo) of the BHT activity, while the antiradical activity resulted equivalent to that of 62.90% (albedo) and 60.72% (flavedo) of the trolox activity. Finally, all extracts did not show any cytotoxic effect on differentiated Caco-2 cells by the AlamarBlue assay while exhibited, by MTT assay, a significant decrease in colon cancer Caco-2 cell viability.
