黄鞘蕊花中的艾里莫芬烷型倍半萜(英文)
Eremophilane Sesquiterpenoids from Coleus xanthanthus
【摘要】 从黄鞘蕊花 (ColeusxanthanthusC .Y .WuetY .C .Huang)的乙酸乙酯部分首次分离得到 3个艾里莫芬烷型倍半萜类化合物 ( 1~ 3) ,其结构由NMR波谱技术及单晶X衍射分析确定。其中 ,化合物 1为新化合物 ,命名为 8,9断裂艾里莫芬1 ( 1 0 ) ,7( 1 1 )二烯8,1 2内酯9酸。首次对化合物 2 ( 2 ,9二氧代优瑞坡森 )和 3( 9氧代宽眼菊素 )的1H NMR和13C NMR谱进行了全归属。
【Abstract】 A new eremophilane sesquiterpenoid, along with two known ones, was isolated from the ethyl acetate soluble fraction of the aerial part of Coleus xanthanthus C. Y. Wu et Y. C. Huang. Their structures were elucidated as 4,5,11trimethyl8,9seco1(10),7(11)eremophiladien8,12olid9oic acid (1), 2,9dioxoeuryopsin (2) and 9oxoeuryopsin (3) by spectral methods. The 1HNMR and 13 C NMR data of compounds 1, 2 and 3 were unambiguously assigned on the basis of twodimensional NMR spectroscopy.
