The free radicals are unstable and highly reactive molecules they interact with organic molecules as protein, lipids, carbohydrates, and DNA, producing in them several structural and functional modifications and alterations. In order to avoid the damage due to the free radicals are used antioxidant. The Encyclia michuacana is a ornato plant of which was isolated (1‐(3′‐hidroxy‐5′‐metoxyphenyl)‐2‐(4″‐hidroxy‐5″‐methoxyphenyl) etano). The aim of this work was evaluate the antiradical properties of this compound. The free radical scavenging activitie of tested compound were measured using the DPPH radical method, monitoring the decrease of absorbance at 517 nm using different concentration (0.014–463 microM). The percentage of the remainig DPPH was calculated and the radical scavenging effects of tested compound was determined calculating 1/IC50. The compound had significant scavenger activity (IC50= 0,18 microM), compared with the caffeic acid (IC50=0.13 microM) that present a similar structure with the isolated compound as is the presence of electrodonadores groups. This type of studies is important to make them because can be the bases to explain some of their biological properties of these compounds.
