Hydrolysis of Sinigrin gives allylisothiocyanate (volatile oil of mustard),
glucose, as well as potassium acid sulphate,
Uses : sinigrin have revealed anti-cancer, antibacterial, antifungal,
antioxidant, anti-inflammatory, wound healing properties
Also used as Rubefacient and Counter irritant.
2- Sinalbin
Source: White mustard seed
HO CH2 S – C6H11O5
CH3O C
HO N – OSO3 - Sinapine+
CH3O Complex organic cation CH3
Sinapine + (Quaternary alkaloid)
CH3
CH=CH-COO-CH2-CH2+N CH3
Sinapine
Hydrolysis of the glycoside sinalbin on the other hand gives:
Acrinylisothiocyanate (phenolic isothiocyanate,pungent tast),
glucose and the acid sulphate of a quaternary alkaloid, named Sinapine
Cation.
Uses : Rubefacient and Counter irritant due to their contents of
thioglycosides.
