Main constituents of polyphenol complex from seagrasses of the genus Zostera, their antidiabetic properties and mechanisms of action.

The present review analyzed the recent experimental studies of the alleviating activity of main constituents of the polyphenol complex from seagrasses of the genus , namely rosmarinic acid, luteolin and its sulfated derivatives, on carbohydrate and lipid metabolism disorders. A number of studies by our group and others, in which various experimental models of diabetes and hyperlipidemia were used, show a therapeutic action of the polyphenol complex and the abovementioned phenolic constituents, when applied separately and in combination. Based on the analysis of the results of these studies, the probable mechanisms of the therapeutic action of these compounds in diabetes and hyperlipidemia were proposed.
