Chokeberry juice is a very rich sou

Chokeberry juice is a very rich source of total polyphenol
compounds, 4772.2mg/l. Proanthocyanidins (PACNs) are
the predominant phenolic compounds in the juice with total
content of 3529.1mg/l. Hydroxycinnamic acids represented
by neochlorogenic and chlorogenic acids are the secondmost
abundant polyphenolswith cumulative content of 806.2mg/l.
Quercetin and quercetin glycosides, isoquercitrin (quercetin-
3-glucoside) and rutin (quercetin-3-rutinoside), as well as
the flavan-3-ol epicatechin are also present as minor components
in the juice. The total amount of anthocyanins is
456.2mg/l juice. Aronia anthocyanin profile is very simple
consisting almost exclusively of cyanidin glycosides, namely,
cyanidin-3-arabinoside, cyanidin-3-galactoside, cyanidin-3-
glucoside, and cyanidin-3-xyloside. Cyanidin-3-galactoside
and cyanidin-3-arabinoside are the predominant representatives
with a cumulative content >90% in the berries
[32]. The high content of polyphenol compounds in the
juice determines its particularly high antioxidant activity
