ABSTRACT
Anti-hyperglycemic agents is a substance that helps a person with diabetes control their level of glucose (sugar) in the blood. It includes insulin and oral anti-hyperglycemic agents. Diabetes is a metabolic disorder characterized by increased blood glucose levels leading to other major complications. Thus, obtaining these anti hyperglycemic agents through easily available flora is necessary. Delonix regia , a tree cultivated worldwide, has also been used as traditional medicine in various disorders. Aim of the project work was to evaluate the anti-hyperglycemic activity in the hydroalcoholic extract of D. regia bark for the treatment of hyperglycemia. The collected bark was dried, powdered and extracted through cold maceration method. The extract was further concentrated to obtain a gummy mass of the hydroalcoholic extract. The extract was subjected to phytochemical analysis through conventional chemical tests and GC-MS. After the identification of the phytoconstituents, they were studied for their clinically proven properties. In-vitro anti-hyperglycemic studies were carried out through assays like alpha-amylase inhibition assay and alpha-glucosidase inhibition assay. The results of the extract were compared with results of standard acarbose. The IC 50 standard values in alpha-amylase inhibition assay and ?-glucosidase inhibition assay were 98.77 and 84.33 ?g/mL, respectively. The IC 50 values of hydroalcoholic extract of D. regia bark in alpha-amylase and alpha-glucosidase inhibition assay were 167 and 116.31 ?g/mL, respectively. From the study, the hydroalcoholic extract of bark of D. regia exhibit anti-hyperglycemic activity compared to standard acarbose.
