Analysis of hydroxypipecolic acids by gas chromatography–mass spectrometry

Mass Spectrometric Fragmentation of Trimethylsilyl and Related Alkylsilyl Derivatives

“…Other compounds examined are α‐tocopherol (vitamin E) (Liebler et al, ), hydroxypipecolic acids (Kitew & Hughes, ), menthols (Bournot et al, ), tetracyclines (Tsuji & Robertson, ), hydroxynoraporphines (Evans & Vouros, ), nicotinamine (Ripperger, ), flavonoids (Füzfai & Molnár‐Perl, ), bisphenol A (Szyrwińska et al, ), phytoestrogens (Ferrer et al, ), haplamine (Ea et al, ), cucurbic acid (Rontani et al, ), mycolic acids (Kaneda et al, ), N , N ‐dialkyl aminoethane‐2‐ols (Reddy et al, ), tricothecenes (Rodrigues‐Fo et al, ), β‐diketone‐containing plant waxes (Tulloch & Hogge, ), alkoxychlorohydrins (Zenkevich & Drugov, ), abietic acids (Azemard et al, ; Rontani et al, ), pectic oligosaccharides from artichoke (Sabater et al, ), lignans (Boldizsár, et al, ), vitamin B6 (Richter, et al, ) and polysaccharides from the Chinese medicinal herb Anemarrhena asphodeloides Bunge (Xia et al, ). Spectra of these compounds are mainly formed by α‐cleavages or cleavages and/or rearrangements of rings and do not present significant additional information on the general fragmentation of TMS derivatives discussed above.…”
