1. Bilberries contain diverse anthocyanins, including delphinidin and cyanidin glycosides. 2. It is a degradation product of cyanidin glycosides from tart cherries in cell cultures. 3. They contain anthocyanin, coloring matters, cyanidin -3-glucoside and sambubioside. 4. Flavonoids ( quercetin and kaempferol ) and proanthocyanidins ( cyanidin and delphinidin ) are present. 5. In certain fruits, the highest concentrations of cyanidin are found in the seeds and skin. 6. One of the major pigments is cyanidin 3-sambubioside, but the total mixture is very complex. 7. One of the major pigments is cyanidin 3-vicianoside, but the total mixture is very complex. 8. The red color of juice can be attributed to anthocyanins, such as delphinidin, cyanidin , and pelargonidin glycosides. 9. Quercetin, cyanidin , delphinidin, pelargonidin, petunidin, peonidin, and malvidin were polyphenols present in saskatoon berries. 10. Other studies have indicated that cyanidin intake may inhibit development of diabetes as well as provide anti-inflammatory effects.
