Antiglycation activity of β-glucogallin from Asparagus racemosus

The increased formation and accumulation of advanced glycation end products (AGEs) has been implicated in pathogenesis of various chronic ailments, including diabetes-associated secondary complications, atherosclerosis, aging, inflammatory and neurodegenerative diseases. Therefore, inhibition of AGEs formation is an imperative strategy for alleviating diverse pathologies. Here, we have demonstrated the AGEs inhibitory activity of β-glucogallin, isolated for the first time from the roots of Asparagus racemosus. β-glucogallin significantly mitigated fructose-, glucose- and methylglyoxal-induced glycation of bovine serum albumin (BSA). Also, the presence of β-glucogallin decreased fructosamine and protein carbonyls content, and increased thiol group content in the fructose-BSA system. These activities of β-glucogallin from Asparagus racemosus underscore its likely pharmacological potential for impeding AGEs-related metabolic disorders.
