Five new acyclic 12-hydroxygeranylgeraniol-derived diterpenoids, i.e., 1–5, were isolated from the seeds of Carpesium triste. The structures including the absolute configurations of the new compounds were elucidated by spectroscopic methods. All the compounds, except for 2, were evaluated for their in vitro cytotoxic activity against cultured SMMC-7721 (human hepatoma), HL-60 (human promyelocytic leukemia)
五个新的无环12 hydroxygeranylgeraniol衍生二萜类化合物,即,1 - 5,从种子中分离天名TRISTE。通过光谱方法阐明了包括新化合物的绝对构型在内的结构。除2种化合物外,所有化合物均评估了其对培养的SMMC-7721(人肝癌),HL-60(人早幼粒细胞白血病)和LO2(人肝细胞)细胞的体外细胞毒活性。
