Abstract magnified image 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.
