Quercetin-3-gentiobioside may show significant inhibitor on AR and AGEs formation activities.

For these reasons, we aimed to assess that A. iwayomogi had potential as anti-diabetic complications agents. We led to isolation of two coumarins (1 and 2), nine flavonoids (3-11), five caffeoylquinic acids (12-16), three diterpene glycosides (17-19), and one phenolic compound (20) from A. iwayomogi. Among them, hispidulin (4), 6-methoxytricin (6), arteanoflavone (7), Quercetin-3-gentiobioside (10), 1,3-di-O-caffeoylquinic acid (13), and suavioside A (18) were first reported on the isolation from A. iwayomogi. Not only two coumarins (1 and 2), nine flavonoids (3-11), and five caffeoylquinic acids (12-16) but also extracts showed significant inhibitor on AR and AGEs formation activities. We analyzed contents of major bioactive compounds in Korea's various regions of A. iwayomogi.
