Abstract

The beta-D-gentiobioside [beta-D-glucopyranosyl(1----6)-beta-D-glucopyranoside] of 3-hydroxy-beta-ionol has been isolated and characterized in quince (Cydonia oblonga) fruit through spectral and chemical studies. Model experiments carried out with this new natural compound revealed its important role as precursor of a number of C13-norisoprenoid flavour compounds of quince essential oil.

摘要

通过光谱和化学研究，从榅桲（Cydonia oblonga）果实中分离并鉴定出了3-羟基-β-紫罗兰醇的β-D-龙胆二糖苷[β-D-吡喃葡萄糖基(1→6)-β-D-吡喃葡萄糖苷]。对这种新天然化合物进行的模型实验表明，它作为榅桲精油中许多C13-去甲类异戊二烯风味化合物的前体具有重要作用。
