Abstract
dc.description.abstract
Phlorotannins are secondary metabolites produced by brown seaweed, which are known for their
nutraceutical and pharmacological properties. The aim of this work was to determine the type of macroporous
resin and the conditions of operation that improve the purification of phlorotannins extracted
from brown seaweed, Macrocystis pyrifera. For the purification of phlorotannins, six resins (HP-20, SP-
850, XAD-7, XAD-16N, XAD-4 and XAD-2) were assessed. The kinetic adsorption allowed determination
of an average adsorption time for the resins of 9 h. The highest level of purification of phlorotannins was
obtained with XAD-16N, 42%, with an adsorption capacity of 183 ± 18 mg PGE/g resin, and a desorption
ratio of 38.2 ± 7.7%. According to the adsorption isotherm the best temperature of operation was 25 C,
and the model that best described the adsorption properties was the Freundlich model. The purification
of phlorotannins might expand their use as a bioactive substance in the food, nutraceutical and pharmaceutical
industries.
