Artemisia annua L.: evidence of sesquiterpene lactones’ fraction antinociceptive activity
BACKGROUND Artemisia annua L. has been used for many centuries in Chinese traditional medicine. Artemisinin, the active principle was first isolated and identified in the 1970s becoming the global back bone to the fight against malaria. Our research group previously developed an economic and ecological friendly process to obtain this compound. In the pursuit to also exploit the residue generate...
متن کاملSesquiterpene lactones from Inula montana L.
Aerial parts of Inula montana were investigated for its sesquiterpenoid composition. Five sesquiterpene lactones, isoinuviscolide, gaillardin, 1beta-hydroxy-3beta-acetoxy-eudesm-4(15), 11(13)-dien-12-8beta-olide, pulchellin-C and pulchellin-E were identified for the first time in this plant. One of them, 1beta-hydroxy-3beta-acetoxy-eudesm-4(15),11(13)-dien-1 2-8beta-olide, is a novel natural pr...
متن کاملCitotoxic Activity of Extracts and Sesquiterpene Lactones from Stachycephalum argentinum
The extracts and sesquiterpene lactones of S.argentinum were assayed to determine their biological activity on Artemia salina. The most active compound was costunolide (1) with LD50= 62 ppm. Introduction Our previous phytochemical study of Stachychephalum argentinum (Asteraceae), revelead the presence of several skeletal types sesquiterpene lactones [1]. In order to explore new natural bioactiv...
متن کاملSelective Oxygenation and Plant-Growth Regulatory Activity of Sesquiterpene Lactones
Presence of a hydroxyl group at the C-3 position in guaianolides and at the C-5 position in alantolides has been established in biologically active compounds that act as plant-growth regulators. Sesquiterpene lactones like dehydrocostus lactone and isoalantolactone were subjected to allylic oxidations with selenium dioxide (SeO2) in combination with urea hydrogen peroxide (UHP) replacing the co...
متن کاملNew sources and antifungal activity of sesquiterpene lactones.
In the search for new sources of sesquiterpene lactones, six Centaurea species have been analyzed. The activity against the fungus Cunninghamella echinulata of (+)-cnicin (1) and (+)-salonitenolide (2), isolated from the Centaurea plants, as well as that of (+)-costunolide (3), (-)-dehydrocostuslactone (4), (-)-lychnopholide (5) and (-)-eremantholide C (6), has been evaluated. Compounds 3 and 4...
