in fruits from red-purple piraya, Hylocereus polyrhizus Britton & Rose.
Inhibitory effect of 2,4-D has been found for several secondary metabolites in culture which has been discussed in detail in the bioproduction of nicotine, shikonin, anthraquinone, anthocyanins and betacyanins
Betalins are another class of natural pigments with reddish purple (betacyanins
) or yellow (betaxanthins) nitrogenous vacuolar components that are widely used as food colorants.
2002; Patkai et al., 1997), which are composed of two main groups: the red betacyanins
and the yellow betaxanthins.

Color Properties and Stability of Betacyanins
from Opuntia Fruits.
But it's harmless, and is due to failure to digest certain betacyanins
(the chemical responsible for making beetroots maroon red).
White 'pitaya' processing to extract the pulp generates a large quantity of residues, such as peels, which can be used for the extraction of betalains (betacyanins
and betaxanthins) (Liaotrakoon et al., 2013; Mello et al., 2015).
A class of water soluble nitrogen containing plant pigments of the order Caryophyllales which consists of the yellow betaxanthins and the violet betacyanins
(Gandia-Herrero, Escribano, & Garcia-Carmona, 2005; Yusuf, Shabbir, & Mohammad, 2017).
Tissue localization of betacyanins
in cactus stems.
Beets have pigments betacyanins
(mostly betaine) and betaxanthine; grapes anthocyanins; and collard greens have chlorophyll, lutein and beta-carotene.
