Glucosides degradation

The problems of very low incorporation and unequal labelling are not encountered with rose petals. Both geraniol (22) and nerol (23) are formed efficiently, as are their )5-glucosides. Degradation of either alcohol showed equal labelling from [2- C]mevalonate at C-4 and C-8. However, more interestingly. 

Cellulose may be degraded by a number of environments. For example, acid-catalysed hydrolytic degradation will eventually lead to glucose by rupture of the l,4-(3-glucosidic linkages. Intermediate products may also be obtained for which the general term hydrocellulose has been given. 

Cyanidin 3-glucoside and cyanidin 3-rutinoside were degraded at 100°C in weak acidic solutions at pH range 1 to 4 under aerobic and anaerobic conditions." The degradation revealed that cyanidin 3-glucoside was more stable under both conditions." ... 

The degradation kinetics of malvidin 3-glucoside in ethanolic solutions under conditions simulating wine accelerated with the increase of ethanol concentration, probably because the extent of anthocyanin self-association decreased with elevated ethanol concentration. ...
