摘要：

Five new sesquiterpenes with a dihydro-beta-agarofuran skeleton were isolated from Maytenus canariensis (Celastraceae) and identified. Their structures and absolute configurations were determined by means of chemical correlations, H-1 and C-13 NMR studies, bidimensional H-1-H-1 and H-1-C-13 correlations, NOE experiments, selective INEPT, and CD studies. The new sesquiterpenes were assayed against Spodoptera littoralis in an election test and exhibited insect antifeedant activity.
