A new geranyl glycoside, geranyl 5-O-beta-D-xylopyranosyl-beta-D-glucopyranoside was isolated as an aroma precursor from tea leaves (Camellia sinensis var. sinensis cv Shuixian) for oolong tea. The isolation was guided by a two-phase acid hydrolysis and/or an enzymatic hydrolysis followed by GC and GC-MS analyses.
