ABSTRACTThe açaí berry (Euterpe oleracea, Mart.), fruit native to the Amazon region and explored mainly in the region of Pará, gained importance in recent years due to potential health benefits, associated with its phytochemical composition and antioxidant capacity, related to its high content of flavonoids. Among these, anthocyanins are responsible for the anti-inflammatory and antioxidant capacity of this fruit. Experimental studies show that due to its composition, the acai berry has antioxidant activity related to its ability to reduce the reactive oxygen species (ROS) and its potential to inhibit cyclooxygenase 2 (COX-2). Another benefit studied is the analysis of their effectiveness in the anti-inflammatory process, being observed inhibition of araquedônico acid-derived mediators, suggesting that the fruit can act in the chronic inflammatory process. Also it was possible to observe that the fruit may have anti-inflammatory effects in healthy patients. Thus, the supplementation of diets with use of acai berry could attenuate inflammation process and oxidative stress, today with more consistent evidence derived primarily from in vitro studies. However, there is still need for further studies to prove the action of this fruit in the mechanisms involved in these processes, isolation of specific compounds and determining their optimal dosage.

Previous studies on palm phyllotaxis deal mainly with the mature trunk. The goals of this study are (i) to determine the relationship between the number of parastichies, the divergence angle, and the plastochrone ratio at the level of the shoot apical meristem; (ii) to examine whether there are fluctuations in the divergence angle; (iii) to interpret the significance of phyllotactic parameters with respect to the mode of growth of the apex. The tubular base of the leaf primordium is more or less asymmetrical, and completely surrounds the shoot apical meristem. The phyllotactic system corresponds to a (2, 3) conspicuous parastichy pair. The mean divergence angle per apex varies between 126.9° ± 9.3° (mean ± SD) and 135. 8° ± 8.0°. Divergence angles for all apices fluctuate within a range of 115.89° to 157.33°. The mean plastochrone ratios between apices varies from 1.35 ± 0.18 to 1.58 ± 0.12. The plastochrone ratio at each plastochrone for all apices ranges from 1.09 to 2.00. There is no correlation between the angle of divergence and the plastochrone ratio. There is a fluctuation in the value of the divergence angle that falls within the range predicted by the fundamental theorem of phyllotaxis. The high value of the ratio of the diameter of leaf primordia over the diameter of the apex, and the long plastochrone might explain the lack of correlation between certain phyllotactic parameters.
