Two new antiinflammatory elemanolides from Centaurea chilensis.
Two previously undescribed elemanolide esters, the 2-methylpropanoate and 2-methyl-2-propenoate of 11,13-dehydromelitensin, were isolated in the course of a bioassay-guided fractionation from the aerial parts of Centaurea chilensis Hook. et Arn., used traditionally to treat 'gout and rheumatism'. The mixture of both substances exhibits anti-inflammatory activity in the carrageenan-induced paw e...
متن کاملSesquiterpene Lactones from Centaurea Solstitzalis
Eight sesquiterpene lactones were isolated from Centaurea solstitialis (yellow starthistle). They are solstitialin A, repin, subluteolide, acroptilin, janerin, cynaropicrin, and the new &tones solstitiolide and episolstitiolide.
متن کاملAn Antibacterial Principle from Centaurea Maculosa.
Cantaurea maculosa, the spotted knapweed, is a common wild plant, aqueous extracts of which demonstrate antibacterial activity against gram-positive and gram-negative bacteria. Of 13 species of Centaurea screened for antibacterial activity by Osborn (1943), only three yielded extracts that were inhibitory to the growth of Staphylococcus aureus and none was active against Escherichia coli. Our C...
متن کاملCynaratriol, a sesquiterpene lactone from Centaurea musimomum
THE TITLE COMPOUND [SYSTEMATIC NAME: 3,8-dihydr-oxy-3-(hydroxy-meth-yl)-9-methyl-6-methyl-enedeca-hydro-azuleno[4,5-b]furan-2(3H)-one], C(15)H(22)O(5), is a sesquiterpene lactone showing the typical tricyclic guaianolide skeleton which has been isolated, together with other related metabolites, from the plant Centaurea musimomum. The present study confirms the mol-ecular structure, assigned by ...
متن کاملPotent anti-platelet constituents from Centaurea iberica.
New naturally occurring nitrogenous compounds 1 and 2, along with a new dimeric lignan glucoside 3, have been isolated from the ethyl acetate soluble fraction of Centaurea iberica. Their structures have been elucidated through spectroscopic techniques. All the isolated compounds showed significant platelet aggregation inhibition.
