Abstract

Unique sesquiterpene alkaloids such as pulchellidine and neopulchellidine and also various types of sesquiterpenolides containing pseudoguaianolides (such as pulchellin and neopulchellin), guaianolides (such as gaillardin and neogaillardin), and eudesmanolides (such as pulchellin B, C, E, and F) have been isolated from Gaillardia pulchellu. 1 A common feature of these compounds is the a-methylene-y-butyrolactone moiety or its equivalent. ...
