ABSTRACT |
|
|
|
Ultrasound-assisted extraction technique
was developed for the extraction of phenolic acids and flavonoids
from pomegranate and Butia. Parameters as ethanol concentration,
temperature and solid to liquid ratio were assessed through an
experimental design and the antioxidant activity
(2,2-diphenyl-1-picrylhydrazyl [DPPH] method) for each assay was
evaluated. The maximum amount of total polyphenol content was
6723.42 and 37.99 mg gallic acid equivalent (GAE)/g of extract for
pomegranate and Butia, respectively. Individual compounds as
phenolic acids and flavonoids ranged depending on experimental
conditions but, on the other hand, the antioxidant activity had
little influence when these variables were studied. Pomegranate and
Butia showed a maximum inhibition of DPPH radicals of 92.35% and
28.50%, respectively. |
