A new active compound from Centaurea species.
The extract containing sesquiterpene lactones of Centaurea iberica (Asteraceae) isolated was separated and a steroidal compound, which is stigmast-1,5-dien-3beta-ol, was purified. The chemical structure was established based on spectroscopic data (UV, IR, MS, 1H NMR, 13C NMR). Both the extract and the compound showed significant antioxidant and antimicrobial activities.
متن کاملGuaianolide and seco-Guaianolide from Salvia nubicola (Lamiaceae)
Salvia is one of the famous genera of the family Lamiacea previously called Labiatae comprising about 800 species throughout the world [1]. Most of the members of this genus are known due to their biologically active chemical constituents specifically reported for anti-tumor activity [2]. A number of Salvia species are used in folk medicines. For example, S. cavaleriei is used for the treatment...
متن کاملNew guaianolide-type sesquiterpene lactones from Inula verbascifolia.
The aerial parts of Inula verbascifolia afforded two new guaianolide-type sesquiterpene lactones. Their structures were determined by spectroscopic methods (IR, MS, 1H NMR, 13C NMR, DEPT, 1H-1H COSY, HMQC, and HMBC).
متن کاملTwo 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 کاملRare hydroperoxyl guaianolide sesquiterpenes from Pulicaria undulata
Pulicaria species, such as Pulicaria undulata, are rich in sesquiterpene lactones. The methylene chloride/ methanol (1:1) extract of P. undulata resulted in the isolation of new sesquiterpenes (1–4), as well as previously reported metabolites (5–14). Structures were elucidated by spectroscopic analyses. Using a mouse peritoneal macrophage bioassay, lipopolysaccharide-induced nitric oxide inhibi...
