The extraction of chamomile flowers using supercritical carbon dioxide was investigated with respect to extraction efficiency and compared with solvent extraction. The stability of matricine, a sensitive constituent of the essential oil of chamomile, in these extracts was studied during
The assignment of the absolute configuration of matricin rests on indirect evidence. On the basis of synthetic, NMR and CD studies with its decomposition product, chamazulene carboxylic acid, we were able to firmly establish the accepted 3S,3aR,4S,9R,9aS,9bS configuration of matricin.

Known determinations of the absolute configuration of guaianolides were collected and found to be few. The absolute configurations of guaianolides rest on the assumption that 7-H always has alpha-orientation. For matricin, only the relative configuration was determined. On the basis
Matricine and its transformation product chamazulene are constituents of chamomile extracts. Both have been demonstrated to exert anti-inflammatory activity in vivo. Since preparations from chamomile are used for the treatment of inflammatory skin and bowel diseases, we studied the effects
