ALVIS, Armando; ARRAZOLA, Guillermo y MARTINEZ, Walter. Evaluation of Antioxidant Activity and Potential Hydro-Alcoholic Extracts of Cúrcuma (Curcuma longa). Inf. tecnol. [online]. 2012, vol.23, n.2, pp. 11-18. ISSN 0718-0764. http://dx.doi.org/10.4067/S0718-07642012000200003.
Phenolic compounds from the rhizome of turmeric (Curcuma longa) were extracted using ethanol at 75% concentration as solvent. The phenolic compounds presented a concentration of 176B.B mg/L expressed as gallic acid and were added to a lipid matrix. The antioxidant and potential activities of the natural product were determined and compared with the antioxidant potential of the synthetic antioxidant (BHT) finding that turmeric extracts had antioxidant potential similar to that of BHT, both tested at the same conditions. The study gives new information on the extraction of natural antioxidant compounds showing the benefits that they have over synthetic compounds.
