[Interrelationship between glucoside-bound and free alcohols during ether oil formation in rose petals].
Some data on the dynamics of free and glucoside-bound monoterpenic and aromatic (beta-phenylethyl) ethers content and the changes in the beta-glucosidase activity in rose petals at different stages of the flower development and on the kinetics of enzymatic hydrolysis of these glucosides are presented. The phase specificity of beta-glucosidase coinciding with the maximal accumulation of glucoside-bound and free alcohols is revealed. The data obtained suggest that the formation of glucosides may precede the accumulation of corresponding free alcohols of terpenic and aromatic origin.
