Three labdane diterpenes 15,16-epoxy-6-hydroxylabda-5,8,13(16),14-tretraen-7-one (leojaponin), (9 alpha, 13S)15,16-diepoxy-70-hydroxy-labd-14-en-6-one (13-epi-preleoheterin), and (9 alpha,13R);15,16-diepoxy-6 beta-liydroxylabd-14-en-7-one (iso-preleoheterin) were isolated from the leaves of Leonurus japonieus, in addition to the previously reported preleoheterin. The structure elucidations were made based on analysis of their spectroscopic data. (c) 2006 Elsevier Ltd. All rights reserved.
