0050. High antioxidant levels in barley grass

Functional Foods for Disease Prevention - Medicinal Plants and Other Foods

Shibamoto, T., Terao, J., Osawa, T., (eds), ACS Symposium Series, 1997.

Background: Flavenoids are a group of chemicals found in many different plants which are known to have a number of properties, including potent anti-oxidative properties.  Oxidation of LDL (sometimes called “bad cholesterol”) has been correlated with atherosclerosis (hardening of the arteries), peripheral vein disease, heart disease and stroke. 1-4  In addition, the build-up of highly reactive and damaging free radicals in mitochondria is decreased by antioxidant flavenoids, reducing the likelihood of tissue damage due to oxidative stress, linked to cancer, heart disease and a number of chronic diseases.

Studies: This study was done in vitro, or entirely in the lab and looked at the ability of 2"-O-glycosylisovitexin (2"-O-GIV), derived from young barley plants to inhibit the oxidation of LDL.  This study also looked at the possible potentiation of the anti-oxidant activity of 2"-O-GIV by Vitamin C.

Conclusions: 2"-O-GIV was very effective as an anti-oxidant both on the oxidation of purified LDL and LDL in blood plasma.  The addition of Vitamin C along with 2"-O-GIV, increased the anti-oxidative potency even more.  This effect was synergistic, meaning that it was greater than simply additive.
