| 1. | Bilberries contain diverse anthocyanins, including delphinidin and cyanidin glycosides.
|
| 2. | Delphinidin gives blue hues to flowers in the genera bilberries.
|
| 3. | It is a rare O-methylated flavonoid, a derivative of delphinidin.
|
| 4. | It is the 3-glucoside of delphinidin.
|
| 5. | Flavonoids ( quercetin and kaempferol ) and proanthocyanidins ( cyanidin and delphinidin ) are present.
|
| 6. | The red-coloured flowers are due to the relative concentrations of delphinidin and malvidin pigments.
|
| 7. | The red color of juice can be attributed to anthocyanins, such as delphinidin, cyanidin, and pelargonidin glycosides.
|
| 8. | Quercetin, cyanidin, delphinidin, pelargonidin, petunidin, peonidin, and malvidin were polyphenols present in saskatoon berries.
|
| 9. | Most frequently occurring in nature are the glycosides of cyanidin, delphinidin, malvidin, pelargonidin, peonidin, and petunidin.
|
| 10. | It also contains acidic polysaccharides and flavonoid glycosides, such as cyanidin and delphinidin, that give it its characteristic deep red colour.
