ANTHRAQUINONES


ANTHOCYANINS


FLAVONOIDS

Flavonoids are also known as Anthoxanthins and are yellow in colour.


CAROTENOIDS

Carotenoids can be split up into two categories: Xanthophylls (which contain oxygen atoms in the chemical structure)and Carotenes (which lack any oxygen atoms in the compound). All are tetraterpenoids, containing the equivalent of 8 isoprene units (aka 40 carbon atoms).


XANTHOPHYLLS

Xanthophylls were previously called Phylloxanthins.


CAROTENES

Carotenes lack any oxygen atoms in the structure and are plain hydrocarbons.


BETALAINS

Betalains can be split up into two categories: Betacyanins with purple/blue colours and Betaxanthins with yellow/orange colours.


BETACYANINS


BETAXANTHINS


FLAVINS (PTERIDINES)


OTHERS

Pyocyanin and ChrysoHermidin, both in Annual Mercury

Azulene in Yarrow.

Piperidines and Hermidin dimers (quinones) in Dog's Mercury

Some Isoquinoline alkaloids, such as Berberine, a quaternary charged alkaloid.

Carthamin(e) - from Safflower (orange/red) - near dimer - (a chalcone attached to a glucose) x2

ThiaRubrines, light-sensitive, coloured, sulphur-containing polyynes found in the Asteraceae plant Perennial Ragweed such as ThiaRubrine A, ThiaRubrine C and ThiaRubrine D.
