Two new insecticidal sesquiterpene polyol esters with a beta-dihydroagarofuran sesquiterpene skeleton, celangulatin A (1), B (2), and two known compounds, celangulin IV (3) and V (4), were isolated from the leaves of Celastrus angulatus by bioassay-guided fractionation. Their chemical structures were elucidated mainly by analyses of the NMR and MS spectral data. Their insecticidal activities against Mythimna separate were demonstrated with the KD50 value of 68.5 and 215.8 microg g(-1), respectively.
通过生物活性导向分离法，从苦皮藤叶片中分离得到了两种具有β-二氢沉香呋喃倍半萜骨架的新型杀虫倍半萜多元醇酯，即苦皮藤素A（1）、B（2），以及两种已知化合物，苦皮藤素IV（3）和V（4）。主要通过对核磁共振（NMR）和质谱（MS）光谱数据的分析来阐明它们的化学结构。它们对粘虫的杀虫活性通过KD50值得到证明，分别为68.5和215.8微克/克。
