Glycosidic Aroma Precursors of 2-Phenylethyl and Benzyl Alcohols from Jasminum sambac Flowers

Abstract

Benzyl 6-0-β-D-xylopyranosyl-β-D-glucopyranoside (β-prime-veroside) (1), 2-phenylethyl β-primeveroside (2), and 2-phenylethyl 6-O-α-L-rhamnopyranosyl-β-D-glucopyranoside (β-rutinoside) (3) were isolated as aroma precursors of benzyl alcohol and 2-phenylethanol from flower buds of Jasminum sambac Ait. The isolation was guided by an enzymatic hydrolysis and GC and GC-MS analyses.
