Radioprotective property of polysaccharide in Tinospora cordifolia.

Radioprotective activity of a polysaccharide preparation from the Indian medicinal plant. Tinospora cordifolia Miers has been established using Saccharomyces cerevisiae X2180 strain as the in vivo test model. The entire activity could be attributed to the radical scavenging capacity of the preparation, as it did not enhance the expression of the protective enzymes, catalase and superoxide dismutase in the yeast cells.
