SALICIN IN AQUEOUS SOLUTIONS AND EXTRACTS: THE REACTION OF HYDROLYSIS
The paper deals with the hydrolysis reaction of salicin as a natural biologically active substance. From the hydrolytic stability of salicin in aqueous media will depend on its biological activity and shelf life of extracts containing salicin. Salicin concentration in aqueous solutions and extracts was determined by HPLC. In experiments it was found that salicin in aqueous solutions at low temperatures (0-25°C) is resistant to hydrolysis. In water extracts of aspen with acidic and alkaline environment the content of salicin over time will increase due to the hydrolysis of the ester of the glycoside.
