| Abstract |
From a 1-BuOH-soluble fraction of a MeOH extract of the leaves of M. japonica, collected in the Okinawa islands, six new ent-labdane glucosides, named microtropiosides A-F, were isolated together with one known acyclic sesquiterpene glucoside. The structures of the new compounds were elucidated by a combination of spectroscopic analyses, and their absolute configurations by application of the β-D-glucopyranosylation-induced shift-trend rule in the 13C NMR spectroscopy and the modified Mosher's method.
