Plant Toxicity and Pharmacological Properties

In addition to the known, 5,4′-dihydroxy-3,6,7,3′-tetramethoxyflavone, five sesquiterpenoid lactones have been isolated from Artemisia cana Pursh. ssp. cana. These include the new compounds canin, artecanin, and ridentin, and the known matricarin and deacetylmatricarin. The structure of canin, a new guaianolide, has been shown to be IV on the basis of chemical transformations and spectral evidence.
