• Antioxidant action
  
  
• Anti-inflammatory action
  
  
• Chemopreventive properties

Free radicals are implicated as mediators in the progression of several chronic diseases and in the deteriorative changes associated with aging.

Tetrahydrocurcuminoids counteract free radicals in 2 ways

• PREVENTION of free radical formation.
  
  
• INTERVENTION whereby already preformed radicals are quenched.

Tetrahydrocurcuminoids are therefore classified as BIOPROTECTANT.

A set of studies performed by Sabinsa Corporation revealed that the Curcuminoids and Tetrahydrocurcuminoids are more potent antioxidants than the commonly used synthetic antioxidant, Butylated Hydroxytoluene (BHT).

ESTIMATION OF ANTIOXIDANT POTENTIAL

• In the DPPH radical scavenging method, the ability of an antioxidant to bind the 1:1 diphenyl-2-picrylhydrazyl-radical (a very stable free radical species) is measured, using various concentrations of the selected antioxidants.
• A compound with high antioxidant potential effectively traps this radical thereby preventing its propagation and the resultant chain reaction.
