Characterization of antioxidant activities from fruits rich in delphinidin or malvidin anthocyanins Hosseini-Beheshti, Elham
Abstract
Anthocyanins have been shown to possess specific antioxidant capacities, which may provide an underlying protective effect against many chronic diseases . Although the antioxidant capacity of anthocyanins has been well established, less is known about the extent to which specific anthocyanin composition affects total antioxidant capacity . The aim of the present study was to compare the antioxidant capacity of two different soft fruits, blackcurrant and grape, which have distinctly different anthocyanin profiles. The anthocyanin profiles of grape and blackcurrant were characterized by HPLC/MS coupled with a diode array detector. Results showed that blackcurrant contained four predominant anthocyanins, cyanidin 3-glucoside, delphinidin 3-glucoside, cyanidin 3-rutinoside, and delphinidin 3-rutinoside . In contrast, malvidin 3-glucoside, delphinidin 3-glucoside, cyanidin 3-glucoside, petunidin 3-glucoside, and peonidin 3- glucoside were the major anthocyanins found in grape . The concentration of individual anthocyanins in all berries was quantified with HPLC/UV using cyanidin 3-glucoside as an external standard . Finally, results showed a greater (p

Description |
Anthocyanins have been shown to possess specific antioxidant capacities, which
may provide an underlying protective effect against many chronic diseases . Although the
antioxidant capacity of anthocyanins has been well established, less is known about the
extent to which specific anthocyanin composition affects total antioxidant capacity . The
aim of the present study was to compare the antioxidant capacity of two different soft
fruits, blackcurrant and grape, which have distinctly different anthocyanin profiles.
The anthocyanin profiles of grape and blackcurrant were characterized by
HPLC/MS coupled with a diode array detector. Results showed that blackcurrant
contained four predominant anthocyanins, cyanidin 3-glucoside, delphinidin 3-glucoside,
cyanidin 3-rutinoside, and delphinidin 3-rutinoside . In contrast, malvidin 3-glucoside,
delphinidin 3-glucoside, cyanidin 3-glucoside, petunidin 3-glucoside, and peonidin 3-
glucoside were the major anthocyanins found in grape . The concentration of individual
anthocyanins in all berries was quantified with HPLC/UV using cyanidin 3-glucoside as
an external standard . Finally, results showed a greater (p
