摘要：

One known and four new sesquiterpenes with dihydro-beta-agarofuran skeletons were isolated from Maytenus canariensis (Celastraceae). Their structures were determined by means of H-1 and C-13 NMR spectroscopic studies, including homo and heteronuclear correlations, H-1 and C-13 long range correlation spectra with inverse detection (HMBC) or selective INEPT and NOE experiments. Their absolute configurations were determined by means of CD studies. Two of the compounds which bad a new basic polyhydroxylated 3,13-dideoxy-evoninol skeleton exhibited powerful insecticidal activity against Spodoptera littoralis and the others proved antifeedant against the same insect in an election test.
