Linalool glycoside

Monoterpenoids occur seldom in ferns. Only two, the (3 5)-linalool glycosides (407, 408), have been reported, both from Arachniodes maxi-mowiczii (256),...

Fig. 4.5 Extent of hydrolysis of glycoside of different volatile compounds during MLF with four strains of malolactic bacteria (MLB). Values are calculated as a percentage ratio between the concentration of glycosides in MLF samples and in a non-MLF control. Sum of 1-hexanol, trans- and CM-3-hexenol, trans- and c/i-2-hexenol sum of isoamyl alcohols, heptanol, and 4-hydroxy-4-methyl-2-pentanol sum of benzyl alcohol and 2-phenylethanol sum of vanillin and benzaldehyde sum of 4-vinylphenol and 4-vinylguaiacol sum of Unalool and a-terpineol sum of nerol and geraniol sum of cis- and rrani-linalool oxides (pyranic and furanic) sum of 3,7-dimethyl-l,5-octadien-3,7-diol and the two 2,7-dimethyl-2,7-octadien-l,6-diol isomers (from Ugliano and Moio 2006, reproduced with permission)...

Techniques were developed for the isolation of monoterpene glycosides (23) and structural studies on those with aglycons at the linalool oxidation state were carried out (24). These compounds... 

Damage to the flavor of "Asti Spumante" wines stored at 20 C when compared with samples held at 10 C was related to losses of linalool and glycosidic precursors of linalool, geraniol and nerol (87). Also the concentrations of a-terpineol, hotrienol, nerol oxide and the furan linalool oxides increased in wines held at ambient temperature. Di Stefano and Castino (87) concluded that low temperature storage retarded these reactions and wines so held retained the characteristic muscat flavor for years.
