title: Four new diterpenoids from Isodon melissoides.
abstract: Three new 11beta,16beta-epoxy-ent-kauranoids melissoidesins I-K (1-3) and one new ent-abietanoid melissoidesin L (4) were obtained from the aerial parts of Isodon melissoides (BENTHAM) H. HARA, their structures were established on the basis of the spectral methods, especially two dimensional (2D) NMR spectroscopy.
