title: The (3R,9R)-3-hydroxy-7,8-dihydro-beta-ionol disaccharide glycoside is an aroma precursor in tea leaves.
abstract: The disaccharide glycoside, (3R,9R)-3-hydroxy-7,8-dihydro-beta-ionyl 6-O-beta-D-apiofuranosyl-beta-D-glucopyranoside was isolated as an aroma precursor from the leaves of Camellia sinensis var. sinensis cv. Yabukita. Its stereochemistry was elucidated on the basis of spectral data and chemical synthesis.
