Glochiflavanosides A - D: Flavanol glucosides from the leaves of Glochidion zeylanicum (Gaertn) A. Juss

Abstract

From the leaves of Glochidion zeylanicum collected in Okinawa, four flavanol glucosides, named as glochiflavanosides A - D were isolated along with known flavone C-glucosides, vitexin and isoorientin. Their structures were elucidated by spectroscopic analyses.
