Melampolides from Enydra anagallis
(Pergamon-Elsevier Science Ltd, 2001-05)
The investigation of an Argentine collection of Enydra anagallis afforded sesquiterpene lactones of the melampolide type two of which were previously known. Their structures were elucidated by spectroscopic methods.
cis,cis-Germacranolides and melampolides from Mikania thapsoides
(American Chemical Society, 2003-12)
The aerial parts of Mikania thapsoides afforded six new cis,cis-germacranolide-type sesquitepene lactones (1-6), of which three (1-3) have an unusual 3,4-epoxy function, and also afforded two new melampolides (7 and 8). ...
Melampolides from Argentinean Acanthospermum australe
(Elsevier Science, 2009-08)
The investigation of the ethanol extract of Acanthospermum australe, collected in the province of Misiones, Argentina, yielded eight melampolides (1-8) of the acanthospermal type. Two of them, 8β-hydroxy-9α-(2-methylbuty ...
Melampolides from Smallanthus macroscyphus
(Pergamon-Elsevier Science Ltd, 2003-01)
Clibadiolide, a sesquiterpene lactone esterified with a homoditerpene from Clibadium pittierii
(1988)
The aerial parts of Clibadium pittierii afforded in addition to known melampolides two new ones, one being esterified with a homoditerpenic acid and the homoditerpenic acid itself. The structures were elucidated by high ...

Effect of different types of sesquiterpene lactones on the maturation of Rhinella Arenarum oocytes
(Cambridge University Press, 2015-06)
The sesquiterpene lactones (STLs) are a large class of plant secondary metabolites that are generally found in the Asteraceae family and that have high diversity with respect to chemical structure as well as biological ...
