Correlación del contenido de fenoles y antocianinas con la capacidad antioxidante Syzygium cumini (L.) Skeels, (Jambolan)

Introduction: Syzygium cumini (L.) Skeels, (jambolam), sin. Eugenia jambolana L, is considered as a source of secondary metabolites with a biological and medicinal potential and these can be associated with its therapeutics properties. Objetive: to correlated the content of polyphenols and anthocyanins with antioxidant capacity in ethanolic and methanolic extracts of S. cumini. Methods: dehydrated and powered fruits, pulp and seeds of S. cumini was subjected to solid-liquid extraction. Total phenolis content was determined by Folin-Cicoulteau method, anthocyanin content was determined by the pH differential method and the potential antioxidant was evaluated using 1,1-difenil–2-picrilhidracil radical stable, 2,2´-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid radical cation and ferric reducing/antioxidant power tests. Results: all extracts showed an important correlation between total phenolis content and antioxidant capacity values, however, in the seed total phenolis content was almost 5 times higher than that obtained in fruit and pulp. Conclusions: all extracts exhibited a considerable antioxidant potential against free radical, and S. cumini could be used as an alternative source of natural bioactive compounds with application in therapeutic research area.
