Abstract:
Three labdane diterpenes 15,16-epoxy-6-hydroxylabda-5,8,13(16),14-tretraen-7-one (leojaponin), (9alpha,13S);15,16-diepoxy-7beta-hydroxylabd-14-en-6-one (13-epi-preleoheterin), and (9alpha,13R);15,16-diepoxy-6beta-hydroxylabd-14-en-7-one (iso-preleoheterin) were isolated from the leaves of Leonurus japonicus, in addition to the previously reported preleoheterin. The structure elucidations were made based on analysis of their spectroscopic data.
