Salicin is a colorless crystal or a white powder. It is hygroscopic. It is widely found in the bark and leaves of various Salix and Populus plants. For example, the content of salicin in the willow bark can reach 25%.
Melting point 197-200 ºC
Specific optical rotation -61.5 º (C=5, WATER)
Water solubility 36 G/L (15 º C), 250 G/L (60 & ordm; C)
Salicin is white crystal; bitter; melting point 199 ~ 202 ° C, specific optical rotation [α] 厙 -45.6 ° (0.6 g / 100 cm 3 absolute ethanol); soluble in water, soluble in boiling water, insoluble In ethanol (1:90), insoluble in ether or chloroform, but soluble in alkaline solution, pyridine or glacial acetic acid. The aqueous solution is neutral, and there is no free phenolic hydroxyl group in the molecule, belonging to the phenolic glycoside compound. Hydrolysis with dilute acid or amygdalin can produce glucose and salicyl alcohol. The molecular formula of salicyl alcohol is C7H8O2; it is oblique colorless needle crystal; melting point 86-87 ° C; heat to 100 ° C sublimation; soluble in water, benzene, soluble in ethanol, ether, chloroform;
Salicin has antipyretic and analgesic effects and has been used in the treatment of rheumatism in the past and has been replaced by other drugs. Because it can produce salicyl alcohol after hydrolysis, it is easy to be oxidized to produce salicylic acid. Therefore, it was the main source of synthetic salicylic acid drugs. Now the pharmaceutical industry has used synthetic methods to produce salicylic acid.
