Phytochemical Profile and Antioxidant Activity of the Tuber and Peel of <i>Pachyrhizus erosus</i>.

ABSTRACT: This study systematically investigated the antioxidant activities and phytochemical profiles of petroleum ether (PE), ethyl acetate (EtOAc), n-butanol (n-BuOH) and aqueous fractions of edible (tubers) and non-edible portions (peels) of Pachyrhizus erosus. The results showed that both the tubers and peels from P. erosus were rich in polyphenols and flavonoids, whereas the EtOAc fraction of peels had the highest polyphenol content, and the PE fraction of peels had the highest total flavonoid content. ABTS, DPPH, and FRAP assays revealed that both the EtOAc fraction of tubers and peels from P. erosus showed significant antioxidant activity, whereas the EtOAc fraction of peels possessed better antioxidant activity than that of tubers. UPLC-Orbitrap-MS/MS analysis indicated
