| Over the past few decades, much effort has been devoted to the study of known food products for medicinal applications. Among these, citrus fruits play a key role in providing a wide range of health-beneficial effects but it generates a huge amount of waste products. In an attempt to recover those wastes, peel of six citrus species (C aurantium, C limetta,C limon, C reticulata, C Sinensis osbeck, and C Sinensis thomson) was evaluated for yield, physicochemical properties, phenolic constituents and antioxidant activities. LC-MS/MS analysis showed that the flavonoids neoeriocitrin, luteolin-7-O-neohesperidoside, scoparin and neohesperidin were chemical markers for C limetta, whereas apigenin-6,8-di-C-glycoside was only detected in C Sinensis Osbeck. PCA analysis revealed significant correlations between antioxidant activities and phenolic contents, highlighting a large interspecific variability. These results suggest that Citrus peel by-products may be valuably recycled by industries due to their high yield and transformed into value-added products, with potential interest for the development of functional foods, cosmetics or preventive therapies for some diseases. |
