Investigation of the metabolites from Gentiana rhodentha FR. (Gentianaceae) by LC-UV and LC-MS resulted in the isolation and identification of a new type of secoiridoid glycoside, rhodenthoside A (1), together with the known secoiridoids sweroside (2) and swertiamarin (3), as well as the known iridoids kingiside (4) and 8-epikingiside (5). The structures were established by 1D- and 2D-NMR, EI-MS, D/CI-MS, FAB-MS, CF-FAB, LC-MS, TSP, LC-MS, and LD-MS data in combination with chemical reactions.
