Total anthocyanins and yellow flavonoids (AnT and LF,
mg/100 g) were extracted from 1 g of pulp in 30 ml of 95%
ethanol/1.5 N HCl (85:15), each sample homogenized for 2 min in
tissue homogenizer type Turrax T-25 digital (IKA Labortechnick).
After that the extract was transferred a 50 ml balloon protected
from light and conserved at rest for 12 h under refrigeration and
then filtered in filter paper and determined by spectrophotometer
at 535 nm for anthocyanins and 374 nm for flavonoids
