ABSTRACT
The polyphenols are part of the composition of many foods, it is known the inhibitory effect of tea and coffee through the tannins on iron intestinal absorption; the yerba mate (Ilex Paraguarensis) is a beverage widely used in South America, that has a high content of a polyphenol named chlorogenic acid. The present work shows the effect of this substance in nonhem iron absorption. An intestinal loop, was made in rats, to form a closed cavity in a small section of intestine tieing it from the pilorous to a distance of six cm. In this closed cavity a solution of 59Fe was injected with different doses of chlorogenic acid; it was living 20, 40 and 120 minutes into the loop, and after this different times, the blood, spleen, liver, femur and intestine were removed to measure the 59Fe uptake to be compared with the control group. The results gave an intense inhibitory effect on the intestinal iron absorption with doses of 0.58 and 1.7 mM per rat of chlorogenic acid at the different times studied (Au)
