ent-Abietanoids and ent-Isopimaranoid Glycosides from Isodon nervosus

Three new and one known ent-abietanoids. i.e.. ent-abienervonins A-C (1-3, resp.) and hebeiabinin B (4), and two new ent-isopimaranoid glycosides, i.e. ent-isopimanervosides A and B (5 and 6, resp.). along with seven known phenolic glycosides were isolated front the aerial parts of Isodon nervosus. The structures of the new compounds were clucidated on the basis of spectroscopic and chemical evidence.
