ent-labdane glycosides from Baccharis pingraea.
The aerial parts of Baccharis pingraea, collected in Chile, afforded, in addition to two diterpene glycosides isolated previously, 14 new ones and two of the corresponding desacyl aglycones. The structures were elucidated by high field 1H NMR spectroscopy. The differences between the collections from Argentina and Chile are discussed.
