摘要
Five caffeoyl conjugates were isolated from the ethyl acetate soluble fraction of Erigeron breviscapus (Van.) Hand_Mazz for the first time. Along with them, nine other chemical constituents were also identified. One new caffeoyl conjugate, erigoster A (1) with a novel basic skeleton was mainly assigned by the using a combination of two_dimensional NMR techniques.
从灯盏细辛 (Erigeronbreviscapus (Van .)Hand_Mazz)的乙酸乙酯部分首次分离得到 5个二咖啡酰基的酚类化合物 (1～ 5 )和 9个其他类型化合物。其中erigosterA (1)为一全新骨架的化合物。利用波谱方法 (1H_NMR ,13 C_NMR ,2D_NMR和FAB_MS等 )对这些化合物的结构进行了鉴定。
