Phytochemical and in vitro anti-diabetic activity of methanolic R. Manikandan*, A.Vijaya Anand1 and G. Durai Muthumani2 |
ABSTRACT |
The intestinal digestive enzymes alpha-glucosidase and alpha-amylase are plays a vital role in the carbohydrate digestion. One antidiabetic therapeutic approach reduces the post prandial glucose level in blood by the inhibition of alpha-glucosidase and alpha-amylase enzymes. These can be an important strategy in management of blood glucose. The aim of the present study was to investigate the phytochemical bioactive compounds of the methanolic extract of Psidium guajava leaves, its in vitro anti-diabetic activity. The assay results suggests that the presence of bioactive compounds, could be responsible for the versatile medicinal properties of this plant including diabetes, the extract exhibit the dose-dependent increase in inhibitory effect on alpha-glucosidase enzyme (upto 89.4%), and alpha-amylase enzyme (upto 96.3%). The current study proves that the antidiabetic activity of methanolic extract of Psidium guajava leaves by in vitro studies. |
