New Sesquiterpene Lactones and Other Constituents fromCentaurea paui
1997
Aerial parts of Centaurea paui afforded, in addition to several known sesquiterpene lactones, the two new elemanolides 2–4, the new elemane derivative 5 as well as the five new heliangolides 14–18. Their structures were elucidated by spectroscopic methods, especially high-field NMR spectroscopy. The structure of the heliangolide 12 previously isolated from this plant, has been confirmed by X-ray diffraction.
Sesquiterpene Lactones fromCentaurea paui
1994
Abstract A new elemanolide and two new heliangolides as well as (2R,3R)-(+)-3-hydroxy-2-methyl-butyrolactone have been isolated from Centaurea paui. The structures were elucidated by high field NMR techniques and chemical transformation.
