Garlic contains more than 200 chemical compounds. The sulfurcontaining
compounds, such as allicin, alliin, and ajoene, are representative
chemicals (Lang et al., 2004; Petrovska and Cekovska,
2010). Allicin has various bioactivities and is responsible for its
strong odor (Block, 1985). Deodorized garlic is less potent in its
biochemical action. The differences between FRGE and HRGE
regarding the production of NO and pro-inflammatory cytokines
and HO-1 induction may be due to structural and component differences,
such as the allicin concentration.
