Abstract

From the aerial parts of Baccharis pingraea the known furolabdane, angeloyl-gutierrezianolic acid (1); two novel diterpenoids, furolabda-6,8- dien-17-oic acid (2) and furolabd-7-en-17-oic acid (3); and the known linear diterpenoid, (10E)-centipedic acid (4), were isolated. LC/MS suggested the presence of gutierrezianolic acid (5). The structures of the new compounds were elucidated by 1D and 2D NMR methods.
