The new secoiridoid glycoside alatenoside ( 6 ) was isolated along with the known secoiridoid glycosides morroniside ( 1 ), (7 α )‐7‐ O ‐methylmorroniside ( 2 ), (7 β )‐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.
