Abstract

The antioxidant cocktail EM-X derived from ferment of unpolished rice, papaya and sea weeds with effective microorganisms (EM) of lactic acid bacteria, yeast, and photosynthetic bacteria is widely available in South-East Asia. Oral administration of a EM-X to rats for 7 days inhibited the ferric-nitrilotriacetic acid (Fe-NTA)-dependent oxidation of fatty acids with protections directed towards docosahexanoic, arachidonic, docosapentanenoic acids, oleic, linoleic and eicosadieonoic acids in the liver and kidney. But only the protections of oxidation to docosahexanoic, arachidonic acid in the kidney were statistically significant. Treatment of rats with EM-X prior to the intraperitoneal administration of Fe-NTA led to a reduction in the overall levels of conjugated dienes (CD) measured in the kidney by 27% and in the liver by 19% suggesting inhibition of lipid peroxidation in these organs. The levels of glutathione and α-tocopherol were largely unaffected suggesting that the protection by the regular strength of EM-X was confined to the inhibition of lipid peroxidation in vivo, a point dependent on the concentrations of bioactive flavonoids.
