Megastigmane glycosides and triterpenoids from Vitis quinguangularis Rehd

► Megastigmane glucosides and cycloartane triterpenoids were studied from the leaves of Vitis quinguangularis Rehd. ► A new megastigmane glucoside (1) and a novel cycloartane nortriterpenoid compound (2) were elucidated by spectroscopic methods. ► Potential chemotaxonomic markers were discussed.
