Diabetes mellitus is a chronic condition characterized by major derangements in glucose metabolism and abnormalities in fat and protein metabolism. Diabetes and infection are among the serious health challenges. This study evaluated the in vitro and hypoglycemic effect and antimicrobial properties of methanol extract of Ipomoea batatas leaf. The antimicrobial activity was done using agar disc diffusion methods and the in vitro hypoglycemic activity was done using Alpha-Glucosidase Inhibitory activities assay, Lipase activity assay, Glucose absorption Capacity assay, Glucose diffusion retardation Index. The result of the percentage alpha glucosidase inhibition ranged from 35.70 to 56.33%. The percentage alpha amylase inhibition ranged from 40.96 to 65.15%. The extract showed significant (p<0.05) dose dependent inhibition of alpha glucosidase and alpha amylase. The extract possess inhibition of lipase activity with percentage inhibition ranging from 72.35 to 81.57%. Though there was non-significant (p<0.05) difference in the various concentrations of the extract on inhibition of lipase activity. The result of the glucose absorption capacity (0.30 to 2.25) was observed to be dose dependent. The glucose diffusion retardation index was time dependent. The antimicrobial susceptibility screening of extracts showed a zone of inhibition that ranged from 2.70 to 15.73mm. The study showed that Ipomoea batatas leaf could be used in the treatment and management of diabetes and infections.
