| 摘要: |
| 从苦皮藤(Celastrus angulatus Max.)根皮的石油醚提取物中分离出二种对粘虫具有毒杀活性的新化合物,以高分辨质谱和核磁共振谱鉴定其分子结构为1β,2β,6α,8β-四乙酰氧基-9α-苯甲酰氧基-12-异丁酰氧基-4α-羟基-β-二氢沉香呋喃及1β,2β,6α,8β-四乙酰氧基-9β-苯甲酰氧基-12-异丁酰氧基-4α-羟基-β-二氢沉香呋喃,分别命名为苦皮藤素Ⅱ,Ⅲ。 |

| Abstract: |
| Two new compounds with strong poisonous effects upon armyworm
(Mythimna separate)were isolated from root bark of Celastrus angulatus.Their
structures were determlned maiuly using HIMS and NMR as 1β,2β,6α,8β-tetraacetoxy-9α-benzoyloxy-12-isobutanoyloxy-4α-hydroxy-β-dihydroagarofuran.
and 1β,2β,6α,8β-tetraacetoxy-9β-benzoyloxy-12-isobutanoyfoxy-4α-hydroxy-β-dihydroagarofuran named as celangulin Ⅱ,Ⅲ respectively. |
