Question

Where are anthocyanins and tannin located?

Answer 1

Anthocyanins are found in the cell vacuole, mostly in flowers and fruits, but also in leaves, stems, and roots. In these parts, they are found predominantly in outer cell layers such as the epidermis and peripheral mesophyll cells.

Tannin is a naturally occurring polyphenol found in plants, seeds, bark, wood, leaves, and fruit skins.
