Abstract 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 . © 1997 John Wiley & Sons, Ltd.
