The development of a method is described for the analysis of hydroxypipecolic acids in crudely purified plant extracts. All eight known naturally-occurring mono-and di-hydroxypipecolic acids could be resolved in a single analysis by gas chromatography-mass spectrometry (GC-MS) of their trimethylsily

A method is presented for the analysis of shellfish tissue for domoic acid, a neurotoxic amino acid responsible for cases of amnesic shellfish poisoning. Tissue extracts are first taken through a two-stage solid-phase extraction clean-up, using reversed-phase and strong cation exchange cartridges. A
A crude polar lipidic extract of the green fresh-water alga Chlorella kessleri cultivated under heterotrophic conditions was separated by high-performance liquid chromatography (HPLC) on a preparative silica gel column into a total of twelve lipid classes, in which the content of fatty acids was det
A method was developed for the analysis and characterization of quercetin and kaempferol in urine following ingestion of Ginkgo biloba tablets. The method utilized gas chromatography/negative ion chemical ionization mass spectrometry of the trimethysilyl derivatives of the flavonoids. Limits of dete
A procedure for characterization of sialic acid-like monosaccharides, i.e. 3deoxy-2-ulosonic acids, by gas chromatography/mass spectrometry is described. The free monosaccharides were reduced with NaBH, and the resulting 3-deoxyaldonic acids were acetylated. Five-membered ring lactones were obtained
