GUZMAN-MALDONADO, Salvador Horacio  e  DIAZ FUENTES, Victor Hugo. Diversity in the phenolic composition and antioxidant capacity of moringa collections in the state of Chiapas. Rev. Mex. Cienc. Agríc [online]. 2017, vol.8, n.7, pp.1641-1645. ISSN 2007-0934.

Due to the importance that the moringa leaf has acquired, its production has increased significantly. Harvesting of the leaf is carried out without taking into account the possible variation in the chemical composition and biological activity of mixtures of leaves with different origin. The objective of the present work was to explore the possible variation in the phenolic composition and the antioxidant capacity of collections in the state of Chiapas. The collection and analysis were carried out in 2014. The total phenols, tannins, phenolics, and the antioxidant capacity of ORAC and TEAC were determined in the leaf. Extensive ranges were found in total phenol content (2436.3-3749.9 mg EAG/100 g), condensed tannins (3.04-39.57 mg EC/100 g), gallic acid, rutin, chlorogenic acid and coumaric acid and the antioxidant capacity TEAC. A variation so high, allows to predict that mixtures of leaves of this species will present little uniformity in its composition and therefore, caution should be exercised when promoting mixtures of moringa leaf as of high nutraceutical value.
