Identification of Passion Fruit Glycosides by Gas Chromatography/Mass Spectrometry

β-d-Glucopyranosides, α-l-rhamnopyranosyl β-d-glucopyranosides, and an α-l-arabinofuranosyl β-d-glucopyranoside have been identified in four passion fruit species by GC/MS analysis of trifluoroacetylated (TFA) derivatives obtained from glycosidally bound volatile compounds, using NCI and/or EI ioniz...

Description
Summary:β-d-Glucopyranosides, α-l-rhamnopyranosyl β-d-glucopyranosides, and an α-l-arabinofuranosyl β-d-glucopyranoside have been identified in four passion fruit species by GC/MS analysis of trifluoroacetylated (TFA) derivatives obtained from glycosidally bound volatile compounds, using NCI and/or EI ionization modes, analysis of the partially methylated alditol acetates obtained after hydrolysis of the glycosidic fraction, and comparison of the retention times of their TFA derivatives with those of synthetic standards. These compounds are quantitatively and qualitatively more important in Passiflora edulis and Passiflora edulis f flavicarpa than in Passiflora ligularis and Passiflora molissima. Only (S)-linalool is present in bound form in P. edulis. (6R,7E,9S)-3-Oxo-α-ionol and 4-oxo-β-ionol glucosides have been identified in P. edulis and P. edulis f flavicarpa, and vomifoliol 1A and 2A glucosides seem characteristic of the first species. Keywords: Passion fruit; glycosidally bound compounds; gas chromatography; gas chromatography/mass spectrometry
