✦ Synopsis

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 trimethylsilyl derivatives. The mass spectra and retention times of these derivatives are provided. The applicability of the method to chemotaxonomic studies using hydroxypipecolic acids is assessed by surveying the patterns of these compounds in herbarium leaf material of 11 species of Inga.

A novel chemical ionization/fast atom bombardment (CI/FAB) source was used to analyse alkenes by chemical ionization mass spectrometry (CI-MS) using copper ions as the ionizing agent. The Cu Y -CI mass spectra showed abundant pseudomolecular adduct ions [alkene-Cu] Y and characteristic fragment ions

Butorphanol is an opioid used as analgesic in humans and other species. In horses, it can cause locomotor stimulation at low doses. This drug is not well chromatographed by GC and so, it is necessary to transform it into a more suitable compound, which can be done by derivatization. The derivatizati
