RESUMO
A review of literature indicates that diabetes mellitus was fairly well known and well conceived as an entity in India with complications like angiopathy, retinopathy, nephropathy, and causing neurological disorders. The antidiabetic study was carried out to estimate the anti hyperglycemic potential of Nardostachys Jatamansi rhizome’s hydro alcoholic extracts in alloxan induced diabetic rats over a period of two weeks. The hydroalcoholic extract HAE1 at a dose (500mg/kg) exhibited significant antihyperglycemic activity than extract HAE2 at a dose (500mg/kg) in diabetic rats. The hydroalcoholic extracts showed improvement in different parameters associated with diabetes, like body weight, lipid profile and biochemical parameters. Extracts also showed improvement in regeneration of β-cells of pancreas in diabetic rats. Histopathological studies strengthen the healing of pancreas by hydro alcoholic extracts (HAE1& HAE2) of Nardostachys Jatamansi, as a probable mechanism of their ant diabetic activity.
