The new secoiridoid glycoside alatenoside (6) was isolated along with the known secoiridoid glycosides morroniside (1), (7α)-7-O-methylmorroniside (2), (7β)-7-O-methylmorroniside (3), alpigenoside (4), and kingiside (5). Complete NMR data for 2, 3, and 4 are presented here for the first time. The structure elucidation and de-replication of the isolates were performed by utilizing a capillary-scale NMR probe and HR-ESI-MS data. Alatenoside (6) represents the first naturally occurring morroniside dimer. ? 2009 Verlag Helvetica Chimica Acta AG, Zurich.
