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 ...
Helivypolide G. A novel dimeric bioactive sesquiterpene lactone
(2004-08-23)
Helivypolide G was isolated from leaves of Helianthus annuus L. cv. Stella. In the course of our ongoing research for new allelochemicals from Helianthus annuus, a novel dimeric bioactive sesquiterpene lactone, helivypolide ...

Detailed H-1 and C-13 NMR structural assignment and relative stereochemistry determination for three closely related sesquiterpene lactones
(JOHN WILEY & SONS LTD, 2008)
A complete analysis of H-1 and C-13 NMR spectra of the trypanocidal sesquiterpene lactone eremantholide C and two of its analogues is described. These structurally similar sesquiterpene lactones were submitted to H-1 NMR, ...
Sesquiterpenes Lactones and Flavonoids from Eremanthus argenteus (Asteraceae)
(NATURAL PRODUCTS INC, 2010)
Two new sesquiterpene lactones 8 alpha-(2`,3`-dihydroxy-2`-methylbutanoyl)-15-desoxygoyazensolide and 16 alpha-(1`,2`-dihydroxy-1`-methylpropyl)-eremantholide have been identified as constituents of Eremanthus argenteus ...
Antileishmanial activity and ultrastructural changes of sesquiterpene lactones isolated from Calea pinnatifida (Asteraceae)
(2019-03-01)
Bioactivity-guided fractionation of antileishmanial active CH 2 Cl 2 phase of MeOH extract from leaves of Calea pinnatifida led to isolation of two sesquiterpene lactones calein C (1) and calealactone C (2), which structures ...
Butanolides as a common feature of Iryanthera lancifolia and Virola surinamensis
(Elsevier B.V., 1998-11-01)
A comparative phytochemical study between pericarps of Iryanthera lancifolia and Virola surinamensis showed that the first one contains a new pair of epimeric 2-alkenyl-gamma-lactones, besides an aryltetralinic lignan and ...
