Antihyperglycemic activity of Typha elephantina leaves using in vivo and in vitro Techniques

Abstract

Looking at the increasing prevalence and inadequate treatments for diabetes mellitus, this study was carried to trace out hypoglycemic potentials of Typha elephantina leaves using in vitro and in vivo studies. α -amylase and α-glucosidase in vitro enzyme inhibition assay were incorporated to determine percent inhibition of Typha elephantina extracts. Typha elephantina methanol extract (TEME) at 125µg/ml in both α-amylase and α-glucosidase exhibited 57.48±1.42 and 53.64±0.92 percent inhibition in contrast to 66.7±0.94 and 70.31±1.25 of standard Acarbose, respectively. However, results obtained in Typha elephantina petroleum ether and chloroform extracts were insignificant. Further TEME antidiabetic properties were investigated by in vivo study, using Streptozotocin induced diabetic rats. Selected 250mg/kg and 500mg/kg doses of TEME were administered orally, which significantly (𝑃 < 0.001) reduces blood glucose of treated animals in contrast to diabetic control. 500mg/kg dose of TEME reduces blood glucose more efficiently. A significant linear rise of body weight and HDL were observed, while there was also remarkable reduction in cholesterol, TG, LDL, VLDL. Reduction in Liver function SGOT, SGPT along with creatinine and urea levels were observed in contrast to diabetic control group. In addition, antioxidant study of Typha elephantina extracts reflected significant results in comparison to that of ascorbic acid in DPPH and H2O2 assay. The whole study signified that Typha elephantina has hypoglycemic potentials.
