| 摘 要： | 从杀虫植物苦皮藤 Celastrus angulatus Max.根皮中分离出2个对东方粘虫 Mythimna separata (Walker) 具有麻醉活性的新化合物。采用高分辨质谱和超导核磁共振谱鉴定其 结构为1α,2α,6β,8β,13-五乙酰氧基-4β-羟基-9β-苯甲酰氧基-β-二氢沉香呋喃1（苦皮藤素Ⅵ）和1α,2α,6β-三乙酰氧基-4β-羟基-8α-呋喃甲酰氧基-9β-苯甲酰氧基-13-异丁酰氧基-β-二氢沉香呋喃2（苦皮藤素Ⅶ）。两者对5龄东方粘虫的麻醉中量(ND50)分别为159.8和59.9μg/g。

| Abstract: | Two new compounds with narcotic action against armyworm (Mythimna separata) were isolated from the root bark of Celastrus angulatus. Their structures were determined as 1α，2α，6β，8β，13-pentaacetoxy-9β-benzoyloxy-4β-hydroxy-β-dihydroagarofuran (Celangulin Ⅵ), 1α，2α，6β-triacetoxy-8α-(β-furancarbonyloxy)-9β-benzoyloxy-13-isobutanoyloxy-4β-hydroxy-β-dihydroagarofuran(Celangulin Ⅶ),mainly by NMR and MS spectral data. The ND50 values (the dose required to make the larval narcotized 50% of the papulation of Mythimna separata) for Celangulin Ⅵ and Ⅶ were 159.8 μg/g and 59.9 μg/g. |
