RESUMO
Background: Glucova Active Tablet is a proprietary Ayurvedic formulation with ingredients reported for anti-hyperglycemic, anti-hyperlipidemic activity and antioxidant properties. Objective: Evaluation of anti-diabetic activity of Glucova Active Tablet on Type I and Type II diabetic model in rats. Materials and Methods: Experimental Type I diabetes was induced in 24 albino rats with intra-peritoneal injection of streptozotocin (50 mg/kg). Type II diabetes was induced in 18 albino rats by intra-peritoneal injection of streptozotocin (35 mg/kg) al ong with high fat diet. The rats were divided in 5 groups for Type I model and 4 groups for Type II model. Normal control group was kept common for both experimental models. Glucova Active Tablet (108 mg/kg) treatment was provided for 28 days twice daily orally. Fasting blood glucose level, serum lipid profi le and liver anti-oxidant parameters like superoxide dismutase and reduced glutathione was carried out in both experimental models. Pancreas histopathology was also done. Statistical analysis were done by 'analysis of variance' test followed by post hoc Tukey’s test, with signifi cant level of P < 0.05. Results and Discussion: Glucova Active Tablet showed signifi cant effect on fasting blood glucose level. It also showed signifi cant alteration in lipid profi le and antioxidant parameters. Histopathology study revealed restoration of beta cells in pancreas in Glucova Active Tablet treated group. Conclusion: Finding of this study concludes that Glucova Active Tablet has shown promising anti-diabetic activity in Type I and Type II diabetic rats. It was also found showing good anti-hyperlipidemic activity and anti-oxidant property.
RESUMO
A simple, accurate, economical and reproducible UV spectrophotometric method for simultaneous estimation of Miglitol and Metformin in combined tablet dosage form has been developed. The developed method employs multi component spectroscopy using 300nm, 270nm, 240nm and 210nm as wavelengths for estimation. Miglitol and Metformin were found to be linear in the concentration range of 0.2-1.2 μg/ml and 2-12 μg/ml respectively. %Assay was found to be in the range of 99.27 – 99.92% and 99.29 – 99.97% for Miglitol and Metformin respectively. Results of analysis were validated statistically in accordance with ICH guidelines.
