Mangosteen and Diabetes

As many as 18.2 million Americans (6.3 percent of the population) have diabetes.

Each year about one million more aged 20 or older are diagnosed with the disorder.

Mangiferin, a xanthone, lowered the blood glucose (sugar) level in type II diabetic mice. From these findings, it seems likely that mangiferin exerts its antidiabetic
activity by decreasing insulin resistance.

In the present study, the effect of mangiferin (a xanthone glucoside, isolated from
the leaves of Mangifera indica) on the atherogenic potential of streptozotocin (STZ)-
diabetes was investigated. In addition, the effect of mangiferin on oral glucose tolerance in glucose-loaded normal rats was also determined. The chronic administration of mangiferin (10 and 20 mg/kg, i.p.) for 14 days significantly as well as markedly improved oral glucose tolerance in glucose-loaded normal rats suggesting its potent antihyperglycemic activity. The accumulating evidences suggest that both pancreatic and extrapancreatic mechanisms might be involved in its antidiabetic or antihyperglycemic action. In conclusion, the present study demonstrates that mangiferin possesses significant anti-diabetic, anti-hyperlipidemic and anti-atherogenic properties thus suggesting its beneficial effect in the treatment of diabetes mellitus associated with hyperlipidemia and related cardiovascular complications.
