Hot water extract of the aerial part of Yacon (Smallanthus sonchifolia, Compositae) showed potent free radical-scavenging activity and inhibitory effects on lipid peroxidation in rat brain homogenate. The most potent antioxidative activity focused on the 50% MeOH-eluted fraction on DIAION HP-20 column chromatography. The structure of the major component in the fraction was identified as 2,3,5-tricaffeoylaltraric acid (TCAA) based on spectroscopic evidence. The antioxidative activity of TCAA is superior to that of natural antioxidants such as (+/-)-catechin, alpha-tocopherol, and ellagic acid, and TCAA also showed selective maltase-inhibitory activity (IC(50) 49 microg/ml). As the hypoglycemic activity of Yacon extract was described in a previous report, the present results showing that the aerial part of Yacon has strong antioxidative activity may encourage its potential use as a food supplement to prevent type II diabetes.
