Abstract: Whole red rice (Oryza sativa L.), consumed as staple food in many countries worldwide, is rich in phytochemicals, mainly antioxidants having health potency. The present study evaluated the neuro- and hepatoprotective efficacy of raw and parboiled whole red rice against streptozotocin (STZ) induced oxidative stress, and antioxidant metabolism both in diabetic and normal non-diabetic rats. Wistar rats were rendered diabetic by a single intraperitoneal (i.p.) injection of streptozotocin (45 mg/kg body wt.), supplemented with raw and parboiled whole red rice for six weeks. Results revealed a drastic increase in oxidative stress markers, such as lipid peroxidation, nitric oxide (NO) level, hydroperoxide (HP) level; antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR), thioredoxin reductases (TR), glutathione S-transferase (GST), acetylcholinesterase (AChE) activity, and decrease in endogenous antioxidant, glutathione (GSH) in diabetic rat. On the other hand, addition of raw and parboiled whole red rice in the diet counteracted the STZ induced oxidative stress in diabetic groups and improved the neuro and hepatic antioxidant system. Both, parboiled and raw red rice forms, exercised similar impacts in diabetic as well as in normal rats suggesting improved antioxidant defence mechanism. Results have shown that the whole red rice possess antidiabetic potential with the antioxidant improving ability, and could be utilized as dietary supplements in diabetes management.
