Sesquiterpene lactones from Achillea crithmifolia
(Elsevier, 1991)
The isolation of guaianolides rupicolin-A, rupicolin-B, their acetates and a new germacranolide 1β,10α-epoxy-3β,9β-diacetoxy-11α,13-dihydrocostunolide, identified by means of PS DQF COSY and PS NOESY, from Achillea ...
Oxidation products of hyperforin from Hypericum perforatum
(Elsevier, 1998)
The isolation of two oxidation products of hyperforin from the aerial parts of Hypericum perforatum and their structure determination by means of 2D NMR methods is reported. The products had the same 1-(2-methyl-1- ...
Guaianolides from Centaurea nicolai: Antifungal activity
(Elsevier, 1999)
A new guaianolide, 3-deacetyl-9-O-acetylsalograviolide A, along with four known closely related lactones, salograviolide A, 9-O- acetylsalograviolide A, kandavanolide and salograviolide B were detected in the aerial parts ...
Highly oxygenated guaianolides from Anthemis cretica subsp. cretica
(Elsevier, 1999)
Two new guaianolides, i.e. anthemolide B and 8-O-angeloyl-9-O- acetylanthemolide B, in addition to 12 known closely related guaianolides were identified in the aerial parts of the flowering plant Anthemis cretica subsp. cretica.
