Resumen
BECAUSE OF THE INCREASING INTEREST IN IMPROVING HUMAN HEALTH WORLDWIDE, PHYTOCHEMICAL ANTIOXIDANTS FROM MEDICINAL AND FOOD PLANTS ARE OF GREAT INTEREST. THE SEARCH FOR NEW SOURCES OF ANTIOXIDANTS IS IMPORTANT FOR THE BEST USE OF BIODIVERSITY. THE OBJECTIVE OF THIS WORK WAS TO EVALUATE THE ANTIOXIDANT ACTIVITY AND THE TOTAL PHENOLIC COMPOUNDS WITH DPPH AND FOLIN-CIOCALTEU ASSAYS FOR EXTRACTS AND FRACTIONS OF BLECHNUM CHILENSE, CURCUMA DOMESTICA AND TAGETES VERTICILLATA. B. CHILENSE WATER-METHANOLIC AND ETOAC FRACTIONS, FOLLOWS OF C. DOMESTICA ETOAC EXTRACT SHOWED AN IMPORTANT QUANTITY OF TOTAL PHENOLIC COMPOUNDS. COMPARED WITH ARISTOTELIA CHILENSIS MEOH EXTRACT, T. VERTICILLATA EXTRACT SHOWED GOOD ACTIVITY, FOLLOWS BY ETOAC FRACTION FROM B. CHILENSE AND BY ETOAC EXTRACT FROM C. DOMESTICA, WITH VERY SIMILAR RESULTS WITH N-HEXANE FRACTION FROM B. CHILENSE AND PETROLEUM ETHER EXTRACT FROM C. DOMESTICA. ALL OF THESE RESULTS WERE GREATER THAN ?-TOCOPHEROL DPPH SCAVENGING ACTIVITY. THE RESULTS SUGGEST THAT ALL PLANTS STUDIED COULD BE ARE NEW SOURCES OF ANTIOXIDANTS AND THE WORK ARE FOLLOWING WITH THE IDENTIFICATION OF THESE COMPOUNDS.
