Anthocyanin is often observed
in the plant kingdom, Anthocyanins
create the blue, red and purple colour in plants such as in bromeliads,
carnivorous, berries, etc. This plant pigment can be used as a
pH
indicator because it changes from red in
acids to blue in
bases.
But not all plants have this pigment for examples the red
pigment
pigment in the plants of the Subclass
Caryophyllidae (e.g. Cactaceae,
Portulacaceae,
Mesebrianthemaceae
etc..) is due to a completely different pigment the
betalain.
(compare with: chlorophyll,
betalain,
carotenoid,
flavonoids) |
