The plant processed herbal formulation have significant role in drug discovery, same time phytoconstituents have high pharmacological potential to treat the various ailments such as diabetes or chronic hyperglycemia. The present research aims to explore and investigate the antidiabetic potential of roots of hyperglycemia Linn. During the study pharmacognosy and formulation of herbal tablet has been done. Fresh roots of plant were collected, two enzymes named as alpha-Amylase and alpha-Glucosidase were obtained from Sigma Aldric. Extraction and fractionation along with phytochemical screening was performed Herbal tablets were made using the direct compression method. The n-butanol fraction of plant extract was mixed with the excipients and compressed into tablets. Different batches of formulations were prepared by dry granulation technique. The maximum in vitro dissolution was found to be with formulation F2 that exhibit the extreme proportion of accumulative release of drug (93.96\%) due to the optimized concentration of PVP and Chitosan and the formulations F2 has potent Antidiabetic Activity and also have antioxidant potential that was performed in this study. Plant extract has been used to formulate herbal tablets. From all five batches of tablets one batch (F2) was found to be best formulation and this was used to investigate the Antidiabetic activity as well as antioxidant activity also. The plants have potential to treat hormonal disorders also hence it can be used to treat the endocrine metabolic disorders.

Background: The increasing frequency of diabetes patients and the reported side effects of commercially available anti-hyperglycemic drugs have gathered the attention of researchers towards the search for new therapeutic approaches. Inhibition of activities of carbohydrate hydrolyzing enzymes is one of the approaches to reduce postprandial hyperglycemia by delaying digestion and absorption of carbohydrates. Objectives: The objective of the study was to investigate phytochemicals, antioxidants, digestive enzymes inhibitory effect, and molecular docking of potent extract. Materials and Methods: In this study, we carry out the substratebased α-glucosidase and α-amylase inhibitory activity of Asparagus racemosus, Bergenia ciliata, Calotropis gigantea, Mimosa pudica, Phyllanthus emblica, and Solanum nigrum along with the determination of total phenolic and flavonoids contents. Likewise, the antioxidant activity was evaluated by measuring the scavenging of DPPH radical. Additionally, antibacterial activity was also studied by Agar well diffusion method. Molecular docking of bioactive compounds from B. ciliata was performed via AutoDock vina. Results: B. ciliata, M. pudica, and P. emblica exhibit significant inhibitory activity against the α-glucosidase and α-amylase with IC50 (μg/ml) of (2.24 {\textpm} 0.01, 46.19 {\textpm} 1.06), (35.73 {\textpm} 0.65, 99.93 {\textpm} 0.9) and (8.12 {\textpm} 0.29, no significant activity) respectively indicating a good source for isolating a potential drug candidate for diabetes. These plant extracts also showed significant antioxidant activity with the IC50 ranges from 13.2 to 26.5 μg/mL along with the significant antibacterial activity towards Staphylococcus aureus and Klebsiella pneumonia. Conclusion: Bergenia extract appeared to be a potent α-glucosidase and α-amylase inhibitor. Further research should be carried out to characterize inhibitor compounds.
