Anthocyanin was another major group of flavonoids in V118.
Among the 3 major anthocyanin peaks detected in the anthocyanin
fraction of the V118 extract, petunidin-3-O-(p-coumaryl)-
rutinoside-5-O-glucoside was the predominant one that accounted
for approximately 67.8% of the total anthocyanins (by
peak area) (Figure 3a). The total anthocyanin content in V118
was 72.31 mg/100 g, which included 9.04, 50.18, and 13.09 mg/
100 g DW of petunidin-3-O-caffeoyl-rutinoside-5-O-glucoside,
petunidin-3-O-(p-coumaryl)-rutinoside-5-O-glucoside, and malvidin-
3-O-(p-coumaryl)-rutinoside-5-O-glucoside, respectively. The concentrations
of these glycosides were calculated based on the
equimolecular conversion using standard curves generated from
their respective aglycones, i.e., petunidin and malvidin. This
concentration was less than that of blueberry (2820 mg/100 g
DW);49 however, tomatoes are consumed in many food preparations
and in larger quantities than seasonal and small fruits like
blueberries. A purple variety of tomato such as the V118 of our
study may have as many health implications as blueberry,
especially when breeding effort is made to further increase the
anthocyanin content.
