Antioxidant Activity Assessment of Plants Used in Huastec Traditional Medicine, Mexico

چکیده
The antioxidant capacity of Ocotea tampicensis (Meissner) Hemsley, Bursera simaruba (L.) Sarg, Pseudobombax ellipticum (Kunth) Dugand, Hamelia patens Jaqc and Croton reflexifolius Kunth was evaluated. Ethanolic and aqueous extractions were performed at concentrations of 15, 30, 60, 120 and 240 mg / 100ml. Colorimetric tests ABTS, DPPH and FRAP were used. The results were expressed as equivalent antioxidant capacity ascorbic acid (AEAC) and percentage capture of free radicals. The aqueous extracts of O. tampicensis and B. simaruba showed the higher percentage capture of free radicals at a concentration of 240mg / 100ml. We hypothesize that the ability to capture free radicals of the species mentioned, are partly responsible for the analgesic and anti-inflammatory activity of these plants used in Huastec traditional medicine. Keyword: Antioxidants; free radicals; inflammation; traditional medicine
