Tareciliosides A—G: Cycloartane Glycosides from Leaves of Tarenna gracilipes (HAY.) OHWI

Abstract

From the 1-BuOH-soluble fraction of a MeOH extract of leaves of Tarenna gracilipes, collected in Okinawa, seven new cycloartane glycosides, named tareciliosides A—G (4—10), were isolated together with three known compounds, D-mannitol (1), (R)-linalool 6-O-α-L-arabinopyranosyl-β-D-glucopyranoside (2), and mussaenoside (3). Their structures were elucidated through a combination of spectroscopic analyses.
