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.
