متن کاملTerpenoids from Achillea setacea.
The aerial parts of Achillea setacea afforded, in addition of a rare monoterpene triol and 12 known sesquiterpene lactones, a new guaianolide containing an endoperoxide ring. Its structure was elucidated by spectral methods.
متن کاملSesquiterpene Lactones from Achillea
The species of genus Achillea, particularly those belonging to the Achillea millefolium group have received a lot of attention so far, due to their use in traditional medicine. Among the numerous chemical compounds isolated from the A. millefolium species, the sesquiterpene lactones are usually one of the major constituents (Seaman, 1982). Continuing our chemotaxonomic examination of Bulgarian ...
متن کاملFlavonoids from Achillea nobilis L.
The detailed investigation of a methanolic extract of aerial parts of Achillea nobilis resulted in the isolation of 10 flavonoids. A new C-glycosylflavone, luteolin-6-C-apiofuranosyl-(1'''-->2'')-glucoside, was isolated besides orientin, isoorientin, vitexin, isoschaftoside, luteolin-7-O-beta-glucuronide, luteolin-4'-O-beta-glucoside and quercetin-3-O-methyl ether and two rare flavonolglycoside...
متن کاملPolyploidy and ecological transfiguration in Achillea.
P olyploidy is a prominent chromosomal/genetical feature in most flowering plant groups (1, 2). Change in the number of chromosome sets (and thus gene dosage) is an important factor in the genesis of new species, in part because plants with higher ploidal levels often have ecological tolerances that differ from those of their progenitors. Plant evolutionists have been very interested in the ori...
