Antioxidative activity of Lavitol (Dihydroquercetin)
Antioxidant activity reflects the ability of a product to destroy or neutralize oxygen free radicals. In general, the higher the product’s ability to destroy or neutralize reactive oxygen species, the higher the level of its antioxidative activity.
In 2008 and 2009, “Ametis” JSC entrusted the Advanced Botanical Consulting and Testing, Inc., Tustin, CA, USA and Brunswick Laboratories, Norton, MA, USA with testing the antioxidative activity of Lavitol (Dihydroquercetin). The method of the Oxygen Radical Absorption Capacity of the dissolved in water product (ORAChydro) was used in the testing. The test results showed that Lavitol (Dihydroquercetin) has very high ORAC value, which exceeds that of some known antioxidants.
