“…All natural compounds from Stizolophus balsamita were isolated before [2,3] but the absolute structure of compound 10 was previously described as 8α-(4'-hydoxy)senecioyloxy-9α-hydroxyparthenolide [15]. whereas our research showed that it should be 8α-(4'-hydoxy)senecioyloxy-9β-hydroxyparthenolide.…”

It can be assumed that sesquiterpene lactones and natural phytosteroids (ecdysones) are the characteristic compounds of the plants from the Asteraceae family. They display certain pharmacological properties and thus are helpful in chemical descriptions of the Asteraceae tribes, subtribes and species. Also some phenolic glycosides found in genus Klasea Cass, and in genus Centaurea L. may be of medical and chemotaxonomical significance. Our studies on the species of the aforementioned taxons and the isolation of several compounds allowed for interesting conclusions of phytochemical and taxonomical nature.

“…11,13-Dihydrostizolin was isolated from a natural source for the first time. It was described earlier as the product of reacting 1 and NaBH 4 [6]. The conformations of the 10-membered rings in 3 and 4 are practically the same and similar to that in the literature for the p-bromobenzoate of tomenphantin A [12].…”

X-ray structure analyses showed that two of them were previously known balsamin derivatives. A third was a crystalline isomorphous mixture of the known lactone stizolin and 11,13-dihydrostizolin in a 53:47 ratio. The biological activities of the balsamin derivatives were investigated.
