Evaluation of effect of alcoholic extract of heartwood of on antioxidant, anti-glycation, sorbitol accumulation and inhibition of aldose reductase activity.

Rising popularity of phytomedicines in various diseased conditions have strengthened the significance of plant-research and evaluation of phytoextracts in clinical manifestations. a medicinal plant, known for its anti-oxidant and anti-diabetic activity is a rich source of phytochemicals with antihyperglycemic and antihyperlipidemic activities. However, its possible role in diabetic complications is not evaluated yet. The present study explores the possible role of alcoholic extract of heartwood of in the treatment of long-term diabetic complications. The alcoholic extract of was evaluated for advanced glycation-end-products formation, erythrocyte sorbitol accumulation and rat kidney aldose reductase enzyme inhibition at the concentration of 25-400 μg/ml using bioassays. Also the phytoextract at the concentration of 10-320 μg/ml was evaluated for its antioxidant potential by antioxidant assays which includes, determination of total phenol content; reducing power assay; nitric oxide scavenging activity; superoxide radical scavenging activity; total antioxidant capacity; total flavonoid content; DPPH scavenging activity; and hydrogen peroxide scavenging activity. The alcoholic extract of across varying concentrations showed inhibitory effect as evident by IC on advanced glycation-end-products formation (55.39 μg/ml), sorbitol accumulation (151.00 μg/ml) and rat kidney aldose reductase (195.88 μg/ml). The phytoextract also exhibited high phenolic and flavonoid contents with promising antioxidant potential against the antioxidant assays evaluated. The present investigation suggests that the phytoextract showed prominent antioxidant, antiglycation property and, inhibited accumulation of sorbitol and ALR enzyme, thus promising a beneficial role in reducing/delaying diabetic complications.
