Heartsease (Viola tricolor L.) is a well-known medicinal plant. Its biological activities are supposed to be related to its antioxidant capacity. Garden pansies (Viola x wittrockiana Gams.) have been crossbred from heartsease and are applied as ornamental plants only. In this study, the mother and the daughter species are compared from a phytochemical point of view. Their flavonoid and anthocyanidin contents are determined by spectroscopic methods recommended by the European Pharmacopoeia 5.0. The compositions of the samples (heartsease and garden pansy varietas of several petal color) are analyzed by high-performance liquid chromatography with UV detection and their antioxidant capacity is determined by trolox equivalent antioxidant capacity assay. Our results suggest that garden pansy, especially its flower, is a promising source of natural antioxidants. In addition, a significant correlation is found between the flavonoid content and antioxidant activity.

UI MeSH Term Description Entries
D005419 Flavonoids A group of phenyl benzopyrans named for having structures like FLAVONES. 2-Phenyl-Benzopyran,2-Phenyl-Chromene,Bioflavonoid,Bioflavonoids,Flavonoid,2-Phenyl-Benzopyrans,2-Phenyl-Chromenes,2 Phenyl Benzopyran,2 Phenyl Benzopyrans,2 Phenyl Chromene,2 Phenyl Chromenes
D000872 Anthocyanins A group of FLAVONOIDS derived from FLAVONOLS, which lack the ketone oxygen at the 4-position. They are glycosylated versions of cyanidin, pelargonidin or delphinidin. The conjugated bonds result in blue, red, and purple colors in flowers of plants. Anthocyanidin,Anthocyanidins,Anthocyanin,Leucoanthocyanidins
