It is effective in the treatment of diabetes mellitus, inflammation, ulcers and diarrhea and preclinical studies have also shown it to possess chemopreventive, radioprotective and antineoplastic properties. The plant is rich in compounds containing anthocyanins, glucoside, ellagic acid, isoquercetin, kaemferol and myrecetin. The seeds are claimed to contain alkaloid, jambosine, and glycoside jambolin or antimellin, which halts the diastatic conversion of starch into sugar. The present review has been primed to describe the existing data on the information on traditional and medicinal use.展开更多

Purposely, jamun fruit and seed’s ethanolic extracts based diets were provided to normal and high sucrose diet induced hyperglycemic/diabetic rats for sixty days. The serum glucose and insulin levels were monitored at monthly intervals to evaluate hypoglycemic effect of jamun extracts.ResultsThe results of instant research depicted that both seed and fruit extracts reduce the blood glucose level significantly and also regulate the insulin levels in hyperglycemic rats. It was noted that jamun fruit extract attenuated serum glucose levels to 5.35% and 12.29% in normal and hyperglycemic rats, respectively; while insulin levels were improved by 2.82% and 6.19%, correspondingly. Whereas, jamun seed extract reduced glucose to 7.04% & 14.36% and showed 3.56% & 7.24% higher insulin levels in normal & hyperglycemic rats, respectively.ConclusionsThe present research revealed that both jamun fruit and seeds have potent prophylactic role against hyperglycemia. In this respect, diet based regimen may be tailored using jamun fruit/seed and their extracts to alleviate hyperglycemia.展开更多
