Popis: Extracts from the epicuticular waxes of leaves from Baccharis linearis collected at the same locality at different seasons of the year were compared in terms of relative yields, chemical composition and biological activity (feeding deterrancy against Spodoptera littoralis larvae and brine shrimp lethality bioassays). Variations detected in the concentration of some of the 13 secondary metabolites isolated in this study are discussed in connection with relevant seasonal changes of incidental environmental factors such as temperature, solar radiation, water stress and presence of predatory insects.
