“…afforded, in addition to Repin (6) 5 and Janerin(7) 7 , small amounts of a further lactone 8, the structure of which was deduced from the H 1 -NMR data especially by comparison with the spectra of 6 and 7 Guaianolides from Acroptilon repens DC. The aerial part of A. repens (Centaurea picris) DC.…”

Sesquiterpene lactones constitute a large and diverse group of biologically active plant chemical that have been identified in the several plant families.The pharmacological properties of interest involving the sesquiterpene lactones are their antibacterial, antifungal and anti-plusmodial activities.Indeed, assessing the biological activities of the sesquiterpene lactones found in plants and their essential oil is of great medicinal importance because they could potentially be utilized as therapeutic agents for the treatment of such infections.

“…Furthermore the guaianolides cynaropicrin (12), 19-desoxyjanenn (13), janerin (14), desacyl janenn-8-O- [4-hydroxytiglate] (15), desacyl janerin (16) as well as the lla,13-dihydro de- rin, the 43,15-epoxide of cynaropicrin (14) and with that of the corresponding 4-hydroxytiglate (15) (19) and the corresponding propionate 1. The structure of the latter easily could be deduced from the 'H-NMR spectrum (Tfble 1) which was of course very close to that of the corresponding acetate (19).…”

replaced by a methyl doublet at b = 1.13 and a doublet quartet at 82.77. Accordingly, these lactones were 11,13-dihydro derivatives of cynaropicrin and of the corresponding 4-hydroxytiglate. The configuration at C-li followed from the coupling J7,11 which was 7 Hz, while a very similar compound with a lictmethyl showed as usual a large coupling (3). The 1H-NMR spectral data of 3 and 5 (Table I) were similar to that of jane

Detailed GC and GC-MS analyses of the essential oils and Et2 O extracts of two Xeranthemum species - X. cylindraceum and X. annum - resulted in the identification of 254 components, in total. Terpenoids constituted the major part of both X. cylindraceum and X. annum essential oils and extracts (51.8-65.7%, and 50.7%, resp.). Among the sesquiterpenoids, the extracts of both investigated taxa contained the guaianolide xerantholide, its 11,13-dihydro derivatives, and two additional sesquiterpene lactones: an eudesmanolide, 11,13-dihydroisoalantolactone, and a pseudoguaianolide, confertin. The last two lactones and both isomers of 11,13-dihydroxerantholide have not been previously detected in Xeranthemum species. The isolated extracts of X. cylindraceum and X. annum were tested in a broth microdilution assay against a panel of microorganisms. The tested extracts demonstrated significant antimicrobial inhibitory activity, ranging from 30 to 260 μg/ml, being most active against Bacillus cereus and Staphylococcus aureus, an important human pathogen, with MIC close in value to those of chloramphenicol. Chemotaxonomic significance of the sesquiterpene lactones' distribution in the taxa investigated in this study and those detected earlier in phylogenetically close species (up to the level of the tribe Cardueae) was also discussed.
