78 results about "Parthenolide" patented technology

Parthenolide is a sesquiterpene lactone of the germacranolide class which occurs naturally in the plant feverfew (Tanacetum parthenium), after which it is named. It is found in highest concentration in the flowers and fruit. Parthenolide's molecular structure depiction is often incorrect regarding the stereochemistry of the epoxide, although X-ray single crystal structures are available. The structure depicted here is the correct one.
