Heliangolides from Viguiera sylvatica
(1989)
The extract of the aerial parts of Viguiera sylvatica gave, in addition to known heliangolides, four new heliangolides related to 1-desoxyniveusin A and one to 11,13-dihydrofuroheliangolide as well as three guaianolides, ...
A heliangolide, 3-hydroxyumbelliferone derivatives and diterpenes from Bahia ambrosioides
(1990)
The aerial parts of Bahia ambrosioides afforded several germacranolides and heliangolides one of which has not been reported previously. Furthermore, in addition to widespread compounds, four 3-hydroxyumbelliferone derivatives ...
Sesquiterpene lactones and other constituents from Calea prunifolia and C. Peckii
(1989)
A re-investigation of Calea prunifolia afforded, in addition to compounds reported previously, a new eudesmanolide, a costol acetate hydroperoxide and four aromatic compounds. Calea peckii gave a large variety of aromatic ...
Diterpenes from Fleischmannia hymenophylla and Brickellia laciniata
(1989)
The aerial parts of Fleischmannia hymenolepis gave in addition to phytol and sesamin a new derivative of beyerene named hymenophylloide. The aerial parts of Brickellia laciniata afforded several new labdane derivatives and ...
(+)-α-copaen-8-one and other constituents from Neomirandea species
(1989)
The investigation of five Neomirandea species gave two known entclerodanes, a heliangolide, a cadinene and a new copaene derivative as well as some widespread compounds.
Further sesquiterpene lactones from viguiera robusta and the potential anti-inflammatory activity of a heliangolide: Inhibition of human neutrophil elastase release
(VERLAG Z NATURFORSCH, 2008)
In addition to known heliangolides, a new eudesmanolide was isolated from the leaf rinse extract of Viguiera robusta (Asteraceae). Structural elucidation was based oil spectral analysis. It is the first report on eudesmanolides ...
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 ...
