A collection from Ecuador gave several ent-labdanes like austrofolin and related compounds. A second collection from Paraguay gave ent-kaurene derivatives and three nor-ent-labdanes.

文摘Austroeupatorium inulaefolium (B. L. Robinson) K. et R. has been investigated. A collection from Ecuador gave several ent-labdanes like austrofolin and related compounds. A second collection from Paraguay gave ent-kaurene derivatives and three nor-ent-labdanes. A third investigation of material from Argentina also gave ent-kaurenes and nor-ent-labdanes, which were only slightly different from those of the Paraguay location.
