Abstract
DDMP saponin, which is widely distributed in leguminous seeds, scaveng ed oxygen radicals when assayed using the xanthine oxidase-NH2OH metho d, electron spin resonance (ESR), and chemiluminescence. One mg of DDM P saponin/ml scavenged superoxide at a degree equivalent to 17.1 units of superoxide dismutase/ml by the ESR spin trapping method. This scav enging activity of DDMP saponin is caused by the DDMP moiety attached to the triterpene aglycone since soybean saponin Bb, which is derived from soyasaponin beta g but which lacks this group, did not show the s cavenging activity.
