Abstract
The antioxidant activity values of CLA (conjugated linoleic acid) synthesized from ricinoleic of castor oil was conducted by using Vissible Spectrofotometer with DPPH (2,2 – difenil -1- pikrilhidrazil) as free radical. Activity determine with 30 menute stability time on 514 - Tocopherol, that on 2 ppm or more was more than 90%.
