Antihyperglycemic and anti-type 2 diabetic activity of marine hydroquinone isolated from brown algae ().

Background And Aims: Brown algae () extract (DP) presented high inhibitory potential against α-amylase. The present study aims to isolate, purify and evaluate the antihyperglycemic and anti-type 2 diabetic activities of marine hydroquinone from DP.

Methods: Marine hydroquinones were isolated using silica gel, HPLC, and NMR spectroscopy was used to identify compound 1 and compound 2 as zonarol and isozonarol, respectively.
