Abstract The antioxidant activities of 70% acetone extract 70% AE from the hypocotyls of the mangrove plant Kandelia candel and its fractions of petroleum ether PF, ethyl acetate EF, water WF, and the LF WF fraction further purified through a Sephadex LH‑20 column, were investigated by the 1,1-diphenyl-2-picrylhydrazyl DPPH free radical scavenging and ferric reducing-antioxidant power FRAP assays. The results showed that all the extract and fractions possessed potent antioxidant activity. There was a significant linear correlation between the total phenolics concentration and the ferric reducing power or free radical scavenging activity of the extract and fractions. Among the extract and fractions, the LF fraction exhibits the best antioxidant performance. The MALDT-TOF MS and HPLC analyses revealed that the phenolic compounds associated with the antioxidant activity of the LF fraction contains a large number of procyanidins and a small amount of prodelphinidins, and the epicatechin is the main extension unit.
