A new dihydroagarofuran-based sesquiterpene, microjaponin (1), was isolated from the stem of Microtropis japonica. Its structure was determined by in-depth spectroscopic and mass-spectrometric analyses. Microjaponin (1) exhibited potent in vitro antituberculosis activity, with an MIC value of 12.5
A new dihydroagarofuran-based sesquiterpene, 8-acetoxymutangin (1), was isolated from the stems of Microtropis fokienensis, together with eight known compounds, including mutangin (2). Their structures were determined through in-depth spectroscopic and mass-spectrometric analyses. Among the isolated
A new dihydroagarofuran-based sesquiterpene, 15-acetoxyorbiculin A, was isolated from the root of Microtropis japonica, together with 13 known compounds. Their structures were determined through in-depth spectroscopic and mass-spectrometric analyses. Among the isolated compounds, celahin C and
Four new compounds, including two new dihydroagarofuranoid sesquiterpenes, 8-benzoyloxymutangin (1) and 15-acetoxyorbiculin G (2), a new lignan derivative, 9,9'- O-di-(Z)-feruloyl-(-)-secoisolariciresinol (3), and a new benzenoid, 5'-methoxyevofolin B (4), have been isolated from the stem of
