Three new beta-dihydroagarofuran sesquiterpene esters, 6 alpha-acetoxy-9 beta-benzoyloxy-1 beta-cinnamoyloxy-8 beta-butanoyloxy-beta-dihydroagarofuran (1), 6 alpha-acetoxy-9 beta-benzoyloxy-1 beta-cinnamoyloxy-8 beta-(2-methylbutanoyloxy)-beta-dihydroagarofuran (2), and 6 alpha-acetoxy-1 beta,8 beta-dibenzoyloxy-9 beta-hydroxy-beta-dihydroagarofuran (6), together with three known compounds (3-5) were isolated from the fruits of Celastrus orbiculatus THUNB. Their structures were elucidated on the basis of spectroscopic methods. Compound 4 showed moderate activity in inhibiting LPS-induced nitric oxide production in murine macrophage RAW264.7 cells with an IC(50) value of 43.7 microM.
从南蛇藤（Celastrus orbiculatus THUNB.）果实中分离得到了三种新的β-二氢沉香呋喃倍半萜酯，即6α-乙酰氧基-9β-苯甲酰氧基-1β-肉桂酰氧基-8β-丁酰氧基-β-二氢沉香呋喃（1）、6α-乙酰氧基-9β-苯甲酰氧基-1β-肉桂酰氧基-8β-（2-甲基丁酰氧基）-β-二氢沉香呋喃（2）和6α-乙酰氧基-1β,8β-二苯甲酰氧基-9β-羟基-β-二氢沉香呋喃（6），以及三种已知化合物（3 - 5）。通过光谱方法对它们的结构进行了鉴定。化合物4在抑制小鼠巨噬细胞RAW264.7细胞中脂多糖诱导的一氧化氮产生方面表现出中等活性，IC(50)值为43.7 microM。
