Evaluation of In vitro Antioxidant and Antidiabetic activity of a Polyherbal formulation

Recent years have seen significant improvements in the identification, management, and study of metabolic illnesses, particularly diabetes. In addition to the present synthetic medicines, current research is focused on developing an alternate source of medication from natural resources for managing diabetes. Objective: To investigate the antioxidant and antidiabetic efficacy of a poly-herbal formulation (PHF) by in vitro models. Methods: The Polyherbal formulation was screened for the presence of phytochemical constituents. The total phenolic and flavonoids content of the formulation was also analysed.  The in vitro antioxidant and antidiabetic activity of the formulation (PHF) were calculated. Results: The Polyherbal formulation showed presence of phenols, flavonoids, steroids, and saponins. The IC50 value of PHF4 was found to be 42.70µg/ml in DPPH radical scavenging assay.  It has shown high levels of phenols (172.6±0.68 mg/g), flavonoids (137.3±0.91 mg/g) and had IC50 values of 422.50 µg/ml and 438.71 µg/ml for amylase and glucosidase, respectively. Conclusion: The results indicate that Polyherbal Formulation (PHF4) had significant antioxidant activity as well as a strong inhibitory effect on α -amylase and α -glucosidase. However, for further validation of the above findings, in vivo antidiabetic study of polyherbal formulation will be carried out using animal models.
