摘要

Further investigation on the aerial parts of Isodon enanderianus afforded a novel asymmetric ent-kauranoid dimer, enanuderinaninJ (1). The structure of the dimer was elucidated by means of spectroscopic methods (including 2D NMR techniques ). Enanderinanin J was a dimer of xerophilusin A and probably formed by [ 4 + 2] cycloaddition.
