Abstract

Extracts of the aerial parts of Viguiera eriophora ssp. eriophora and Viguiera puruana afforded, in addition to known compounds, six new heliangolides and a germacrolide, whose structures were determined by spectral analysis. HPLC analysis and LC NMR experiments revealed the natural occurrence of the compounds in glandular trichomes. The taxonomic relevance of the results is briefly discussed.

摘要

绒毛叶假泽兰（Viguiera eriophora ssp. eriophora）和普鲁纳假泽兰（Viguiera puruana）地上部分的提取物，除了已知化合物外，还得到了六种新的千里光内酯和一种吉马内酯，其结构通过光谱分析确定。高效液相色谱分析和液相核磁共振实验表明这些化合物天然存在于腺毛中。本文简要讨论了这些结果在分类学上的相关性。
