Polyphenols from flowers of Magnolia coco and their anti-glycation effects

Biosci Biotechnol Biochem. 2017 Jul;81(7):1285-1288. doi: 10.1080/09168451.2017.1292837. Epub 2017 Feb 20.

Abstract

We investigated the inhibitory effects of several plant extracts on advanced glycation end-products (AGEs) formation. Among tested samples, the flower extract of Magnolia coco showed significant inhibition of AGE formation. We isolated and characterized procyanidin oligomer and four other compounds from the flowers, and evaluated their inhibitory effects on AGE formation and the AGE-derived crosslink-cleaving activity of the isolated compounds.

Keywords: AGE-derived crosslink-cleaving activity; Magnolia coco; advanced glycation end products (AGEs); procyanidin oligomer.
