Abstract Four populations of Parthenium tomentosum var. tomentosum were examinated. In addition to the known lactones, ivalbatine, acetyl ivalbatine, parthomentine, incanine and ligulatine C, three new pseudoguaianolides: 4- O -desacetyl ligulatine C; 1-dehydroperuvinine and parthoximentine were also isolated. Chemical and spectroscopic methods were used for their structural determination.
摘要 Parthenium tomentosum var. 的四个种群。绒毛进行了检查。除了已知的内酯、伊伐巴汀、乙酰伊伐巴汀、帕多门汀、蒺藜和 ligulatine C 之外,还有三种新的假愈创木酚内酯:4-O-去乙酰基 ligulatine C;还分离了1-脱氢peruvinine 和parthoximentine。化学和光谱方法用于它们的结构测定。
