Abstract	dc.description.abstract	A bioassay-guided purification of the extracts of Nothofagus dombeyi and N. pumilio leaves yielded several triterpenes and flavonoids including 2-O-acetylmaslinic acid, 3-O-acetyl 20,24,25-trihydroxydammarane, and 3,20,24,25-tetrahydroxydammarane as new natural products. All the isolated compounds were assessed for antifeeding activity against the 5th instar larvae of Ctenopsteustis obliquana. 12-Hydroxyoleanolic lactone and pectolinarigenin from N. dombeyi and dihydrooroxylin A from N. pumilio, showed significant antifeeding activity.	en
