Sesquiterpene lactones of Anthemis alpestris

Sesquiterpene lactones and other constituents of three Cardueae from Cyprus

Composition and antimicrobial activity of the essential oil of Achillea falcata L. (Asteraceae).

The composition of the essential oil from aerial parts of Achillea falcata L. (Asteraceae) growing wild in Lebanon was analysed by GC and GC–MS; 58 compounds, representing 94.4% of the oil, were identified. Isomers of the cyclobutane ethanol, 1-methyl-2-(1-methylethenyl), grandisol (21.4%) and fragranol (16.8%) were the main components of the oil. Also abundant were artemisia ketone (5.2%), terpinen-4-ol (4.5%) and 1,8-cineole (4.0%). The essential oil shows inhibitory activity mainly against Gram-positive bacteria.

Sesquiterpene lactones from Centaurea sphaerocephala ssp. sphaerocephala

Abstract Aerial parts of Centaurea sphaerocephala ssp. sphaerocephala furnished sesquiterpene lactones commonly found in Centaurea species as well as a new germacranolide and a new elemadienolide.

Guaianolides and other terpenoids from Anthemis aetnensis

Aerial parts of Anthemis aetnensis furnished the guaianolides hydruntinolide A and B and a number of new analogues, two new germacradienolides, 1-β-hydroxyarbusculin and the isofraxidin derived sesquiterpene ether 7-acetoxypectanone.
