Abstract:
The strawberries (Fragaria x ananassa) of Rosaceae family are an accomplished source of bioactive compounds such as ascorbic acid and diverse range of polyphenols including anthocyanins, phenolic acids, flavonols, ellagitannins etc. These phenolic compounds classify strawberry as an important health promoting food. Strawberries are proved to have potent antioxidant capacity in various in vitro assay systems. The in vivo beneficial effects are getting explored against various ailments including cancer, metabolic syndrome, and cardiovascular diseases. The present research study was designed to analyze the effect of strawberry fruit extracts (water and methanol) against alloxan induced hyperglycemia in albino rats of Wister strain. Upon alloxan (150mg/kg body weight) induction, the diabetic animals showed marked increase in the values of plasma glucose, urea, uric acid, creatinine and concomitant decrease in body weight and plasma insulin level. The oral administration of strawberry extracts for 45 days in diabetic animals reversed the biochemical changes significantly (P0.05) to near normal. Furthermore, the restoration of body weight loss was also observed. The results suggest that the strawberry extract has effective hypoglycemic activity against alloxan diabetes. The poly phenolic antioxidant contents of the strawberry fruit extracts are responsible for the observed biological effect.
