摘要：

Two diterpenoid acids, (-)-cis-and (-)-trans-ozic acid, were isolated from the wild sunflower species, Helianthus occidentalis. This is the first report of the levorotatory optical enantiomorph of trans-ozic acid and the first isolation of both acids from Helianthus. Because H. occidentalis is resistant to sunflower insect pests and various diterpenoid acids have shown antibiotic activity to several insect species, the presence of cis-and trans-ozic acid may contribute to host plant resistance. © 1979, American Chemical Society.
