title: (Z)-3-hexenyl and trans-linalool 3,7-oxide beta-primeverosides isolated as aroma precursors from leaves of a green tea cultivar.
abstract: 6-O-beta-D-Xylopyranosyl-beta-D-glucopyranosides (beta-primeverosides) of (Z)-3-hexenol and trans-linalool 3,7-oxide were newly isolated from fresh leaves of a tea cultivar (Camellia sinensis var. sinensis cv. Yabukita). In addition, the already identified beta-primeverosides of benzyl alcohol, methyl salicylate, and trans-linalool 3,6-oxide from an oolong tea cultivar were isolated from the Yabukita cultivar. It was confirmed that all aglycones of the linalool oxide glycosides isolated here were of the optically active S-form by chiral GC after enzymatic hydrolysis with glycosidase.
