Glycosidically bound eugenol and methyl salicylate in the fruit of edible Passiflora species

The beta-D-glucopyranoside and 6-O-alpha-L-rhamnopyranosyl-beta-D-glucopyranoside of methyl salicylate and the B-D-glucopyranoside of eugenol have been characterized in purple passion fruit (Passiflora edulis SIMS) by GC and GC/MS of their trifluoroacetylated derivatives. The structural elucidations were performed by comparison of chromatography and mass spectrometry data with those of synthesized glycosides. Identifications and (semi)quantifications of some of them have been extended to yellow passion fruit (Passiflora f flavicarpa), granadilla (Passiflora ligularis Juss.), and banana passion fruit (Passiflora mollissima).
