title: Purification and characterization of pentagalloylglucose, and alpha-glucosidase inhibitor/antibiotic from the freshwater green alga Spirogyra varians.
abstract: An alpha-glucosidase inhibitor/antibiotic was purified from the freshwater green alga Spirogyra varians and was determined to be the pentagalloylglucose 3-O-digalloyl-1,2,6-trigalloylglucose.
