were detected. Additionally, differences in the
content of petunidin-3-caffeoylrutinoside-5-glucoside, petunidin-
2-p-coumaroylrutinoside-5-glucoside and malvidin-3-p-coumaroylrutinoside-
5-glucoside were found between the samples
of raw potatoes examined, and higher levels of those anthocyanins
were found in the Blue Congo variety of potato. In tubers of the
Salad Blue variety, the same derivatives were detected; however,
in distinctly lower quantities than in the Blue Congo or Valfi potatoes,
a decrease that was particularly notable for petunidin-2-pcoumaroylrutinoside-
5-glucoside. The red-fleshed Herbie 26 potatoes
had the highest level of pelargonidin-3-p-coumaroylrutinoside-
5-glucoside and also contained notable quantities of
pelargonidin-3-rutinoside-5-glucoside, pelargonidin-3-feruloylrutinoside-
5-glucoside and pelargonidin-3-caffeoylrutinoside-5-
glucoside.
