Abstract
Phytochemical investigation of the roots of Rothmannia wittii led to the isolation of three new iridoid glucosides, named rothmanniosides A-C (1-3), and nine known compounds (4-12). Their structures, including their absolute configurations, were elucidated by thorough analysis of mass spectrometric and NMR spectroscopic data, together with CD calculations. Compounds 4 and 11 are reported from the Rubiaceae family for the first time.
