南鹤虱中两个新的倍半萜类化合物（英文）

Two New Sesquterpenoids from Fructus Carotae

从中药南鹤虱(Fructus carotae)中分离纯化得到7个倍半萜类化合物,分别鉴定为7-ethoxy-4(15)-oppositen-1β-ol(1),11-乙酰氧基-8β-当归酰氧基-15-甲氧基-4α,5α-环氧愈创木烷-3-酮(2),11-乙酰氧基-8β-丙酰氧基-4-愈创木烯-3-酮(3),1-oxo-5α,7αH-eudesma-3-en-15-al(4),1β-hydroxy-4(15),7-eudesmadiene(5),1β-hydroxy-4(15),5E,10(14)-germacratriene(6),1β-hydroxy-4(15),5-eudesmadiene(7).其中化合物1和2为新的化合物,新化合物的结构进一步通过HR-ESIMS,1D NMR和2D NMR等光谱技术确定.

Seven sesquterpenoids were obtained from the Chinese traditional medicine, Fructus carotae, and their structures were identified as 7-ethoxy-4（15）-oppositen-1β-ol （1）, 11-acetoxy-8β-angeloyloxy-15-methoxy-4α,5α-epoxyarbutane-3-one （2）, 11-acetoxy-8β-propionyl-4-guaien-3-one （3）, 1-oxo-5α,7αH-eudesma-3-en-15-al （4）, 1β-hydroxy-4（15）,7-eudesmadiene （5）, 1β-hydroxy-4（15）,5E,10（14）-germacratriene （6） and 1β-hydroxy-4（15）,5-eudesmadiene （7）. Compounds 1 and 2 were new sesquterpenoid compounds, and their structures were determined by the analysis of HR-ESIMS, 1D NMR and 2D NMR.
