摘要：
Four new insecticidal sesquiterpene polyol esters with a beta-dihydroagarofuran sesquiterpene skeleton, celangulatin C (1), celangulatin D (2), celangulatin E (3), and celangulatin F (4), and five known compounds 5-9 were isolated from the low-polar toluene extracts of the root bark of Celastrus angulatus by bioassay-guided fractionation. Their chemical structures were elucidated mainly by analyses of MS and NMR spectral data. Celangulatin C, E and F showed LD50 against Mythimna separata were 280.4, 1656.4 and 210.5 mu g m(-1), respectively.
