Title
  Action of methanolic
  extract of mung bean hulls as inhibitors of lipid
  peroxidation and non-lipid oxidative damage.

Abstract
  The antioxidant effects of methanolic
  extract of mung bean hulls (MEMBH) on lipids and non-lipids,
  including liposome, carbohydrate, protein and 2'-deoxyguanosine (2'-dG), were
  investigated. MEMBH exhibited a remarkable antioxidant effect in a liposome
  model system, indicating that the extract was an inhibitor
  of lipid peroxidation. The inhibitory effect of MEMBH on deoxyribose damage
  was amount-dependent and it afforded considerable protection against damage
  to deoxyribose. In addition, MEMBH at low amounts was more effective in
  protecting protein oxidation. Furthermore, the oxidation of 2'-dG to
  8-hydroxy-2'-deoxyguanosine (8-OH-2'dG) was inhibited by MEMBH. These results
  show that the extract also was an inhibitor of non-lipid
  oxidation damage. The extract exhibited metal binding
  ability and scavenging activity for hydrogen peroxide and hydroxyl radical,
  which may explain the mechanism of their protecting lipids and non-lipids
  from oxidative damage.
