title: Bioactive furanoeremophilanes from Senecio otites Kunze ex DC.
abstract: The furanoeremophilanes 6 beta-angeloyloxy-1,10-dehydrofuranoeremophilan-9-one (1), 6 beta-hydroxy-1,10-dehydrofuranoeremophilan-9-one (2) and 6 beta-propionyloxy-1,10-dehydrofuranoeremophilan-9-one (3) were isolated from Senecio otites, their structures elucidated by spectral analyses, and their insecticidal and phytotoxic properties evaluated. Compounds 1-3 proved to be effective aphid antifeedants against Myzus persicae and Rhopalosiphum padi and had postingestive negative effects on Spodoptera littoralis larvae. These compounds did not have any phytotoxic effects on Lactuca sativa.
