Two unusual conjugated fatty acids, parinaric acid and α-eleostearic acid, are present in several Impatiens species, but not in congener Hydrocera triflora.

ABSTRACT: Parinaric and α-eleostearic acids are unusual conjugated fatty acids. Unusual fatty acids, in general, are known to have roles in defense response; however, the role of parinaric acid in I. balsamina is not known, nor is it known whether it occurs in different species of Impatiens or its closest monotypic relative, Hydrocera triflora (L.) Wight & Arn. The aim of the study was to (a) characterize the fatty acid composition of 21 species of Impatiens and H. triflora and (b) determine whether parinaric and α-eleostearic acids are present in these taxa and, if so, (c) whether there is interspecific and intraspecific variation in parinaric acid content. Fatty acid profiling was done using gas chromatography and mass spectrometry (GC-MS). To uncover taxonomic p
