New protein glycation inhibitory free radical scavenging compound from Duranta repens L.

Methanol extract of D. repense possess potent antioxidant compounds. Iridoids augmented glucose induced glycation of BSA. Lignans displayed antiglycation activity. The (−) isomer of lignan 5′Methoxyisolariciresinol (6) was five times more potent in inhibiting glucose induced generation of AGEs in BSA.
