Abstract
In this article, we have studied the
changes in phytochemical contents and antioxidant properties of blackberry (Rubus caesius L.) fruits naturally grown
in Battalgazi district of Malatya province during the ripening process. It was determined the total phenolic (23.82-151.36 mg GAE/g extract), total flavonoid (5.65-25.72
mg RE/g extract), and total flavonol (1.30-5.40 mg QUE/g extract) contents of
twelve extracts prepared by six different solvents. According to these results, it was concluded that
phytochemical contents were higher in unripe fruit extracts than the ripe
fruits.
The reducing power, chelating capacity
of metal ions and antioxidant activity of each extract were determined using
the DPPH free radical scavenging method. The working conditions in which the
antioxidant activity values were best obtained by the DPPH method were
explained according to each extract extraction method and it was seen that the
best result was the acidified water extract of the unripe fruit (IC50
27.24 ± 0.00 µg/mL).
The results showed that R. caesius L. can be consumed as a
natural antioxidant due to its antioxidant properties. Supporting these results with in vivo studies will
also clarify the health promoting properties of antioxidant activity of R.
caesisus fruit.
