Fast determination of anthocyanins and free pelargonidin
in fruits, fruit juices, and fruit wines by high-performance liquid chromatography using a core-shell coloumn.
Common anthocyanidins found in fruits and vegetables are cyanidin, pelargonidin
, delphinidin, malvidin, petunidin and peonidin, which are having a different number and position of the hydroxyl and methoxyl group substituents (31).
This subgroup includes a long list of compounds, such as cyanidin, delphinidin, epigenidin, leucocyanidin, leucodelphinidin, pelargonidin
, prodelphinidin, and propelargonidin.
Mixed calibration solutions were prepared ranging from 0.5 to 15 ppm for each individual anthocyanidin (delphinidin, cyanidin, petunidin, pelargonidin
, peonidin, and malvidin) purchased in Extrasynthese.

Prooxidant properties have been also observed for some blackcurrant polyphenols present in the tested BC extract, such as cyanidin and delphinidin, as well as malvidin, pelargonidin
or peonidin, and their glucosides .
PFP contains acylated glucosides of peonidin, pelargonidin
, malvidin, petunidin and delphinidin.

Antioxidant activities of pomegranate fruit extract and its anthocyanidins; delphinidin, cyanidin, and pelargonidin
Anti-inflammatory effects of flavonoids: genistein, kaempferol, quercetin, and daidzein inhibit STAT-1 and NF-kappaB activations, whereas flavone, isorhamnetin, naringenin, and pelargonidin
inhibit only NF-kappaB activation along with their inhibitory effect on iNOS expression and NO production in activated macrophages.
This plant gathers medicinal importance due to the presence of eugenol, fernesol, nerol, tryptanthrine, indigo, indirubin, isatin, linoleic acid, [alpha]- and [beta]-amirins, carotenoids, sterols, phenolic compounds, rutin, quercetin, kaempherol, famaricetin, luteolin, saponin, alkaloids, terpenoids, tannins, triterpenoids, anthocyanin, flavonoids, steroids, anthraquinones, citric acid, tartaric acid, couroupitine, and pelargonidin
