title: Sesquiterpenes from Achillea pannonica Scheele.
abstract: From dichloromethane extracts of flowerheads of Achillea pannonica Scheele three sesquiterpenes were isolated and identified: 11,13-dehydrodesacetylmatricarin, (6E)-5-tigloxy-9-hydroxynerolidol and alpha-longipin-2-en-1-one. The structures were determined by MS, IR and NMR spectroscopic analyses, (6E)-5-Tigloxy-9-hydroxynerolidol is reported here for the first time. Additionally spathulenol, a compound of the essential oil was identified using GC-MS and GC-FTIR.
