LC-MSn analysis of the cis isomers of chlorogenic acids
(ELSEVIER SCI LTD, 2008)
The behaviour of cis isomers of selected mono- and di-acyl chlorogenic acids produced by UV-irradiation has been investigated by LC-MSn. cis Isomers fragment identically to the more common trans isomers. cis-5-Acyl chlorogenic ...

Identification of quinolactin alkaloids from fungi associated to Brazilian red algae Dichotomaria marginata by LC-PDA-MS and LC-MSn
Fungi isolated from marine organisms have been shown to produce several interesting secondary metabolites with important biological activities. Such chemical diversity may be associated to environmental stress conditions ...
Use of porous graphitic carbon column for the separation of natural isomeric tropane alkaloids by capillary LC and mass spectrometry
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-02-24)
This study presents the outstanding chromatographic selectivity of a porous graphitic carbon support for the separation of four isomeric tropane alkaloids from the stem-bark of Schizanthus grahamii (Solanaceae). Capillary ...

Amnesic shellfish poisoning toxins in bivalve molluscs in Ireland
(PERGAMON-ELSEVIER SCIENCE LTD, 2005-12-15)
In December 1999, domoic acid (DA) a potent neurotoxin, responsible for the syndrome Amnesic Shellfish Poisoning (ASP) was detected for the first time in shellfish harvested in Ireland. Two liquid chromatography (LC) methods ...
