摘要：

Three prenylated benzoic acid derivatives have been isolated from the leaves of the Panamanian shrub Piper taboganum, including a new compound we have named as the methyl ester of taboganic acid. These three compounds were characterized by means of spectroscopic analysis and a chemical interconversion. In laboratory bioassays, two are significant repellents of the leafcutter ant Acromyrmex octospinosus at or below their apparent concentration in this plant, suggesting an effective natural defence against this insect pest. © 1982.
