This is a nitrogenous anthocyanin, and its constitution has not yet been established (c/. Pucher et al., 1938 Chmielewska, 1938). Apart from the Chenopodiales in which they are repeatedly found the nitrogenous anthocyanins are limited in their distribution to four other orders, but only a few of the species mentioned are used as food in Cactales, Opuntia spp., and in Caryophyllales, Mesembryanthemum spp. Chmielewska et al. (1936, 1938) have found that the anthocyanin of red cabbage is a bioside of cyanidin acylated with sinapic acid, and that of a purpleskinned variety of potato (Chmielewska, 1935) a bioside of malvidin acylated with p-coumaric acid otherwise no identifications of the anthocyanins in vegetables appear to have been attempted. 

Dry masa flours are currently being supplemented with common bean (Phaseolus vulgaris) and cactus (Opuntia spp.) flour. Both beans and cactus flours are rich sources of dietary fiber. The green-colored cactus supplemented tortillas, rich in both soluble and insoluble dietary fiber, are mainly consumed by diabetic and hyper-cholesterolemic people to lower glycemic index and blood cholesterol.

E. intermedia collected in one area and in E. gerardiana. Specimens of E. intermedia collected in other areas contained N-methylephedrine in addition, as did E. gerardiana var. sikkimensis, E. nebrodensis var. procera, an unidentified Ephedra sp., and various commercial samples of the drug Ma-Huang. The cactus Opuntia clavata has been shown to contain iV-methyltyramine. Whereas no alkaloids could be detected in a number of Thelocactus spp., seven cacti of the genus Gymnocactus were found to contain various amounts of N-methyl- -phenethylamine, in some cases accompanied by hordenine and iV-methyltyramine. ... 

Seeds of some species such as Linum usitatissimum, Citrus spp, Empetrum nigrum, Poa alpina and Opuntia show polyembryony. In different species this can result from one of several causes, including cleavage of the zygote, development of one or more synergidae, existence of more than one embryo sac per nucellus and various forms of apogamy and adventitious embryony. Clearly, in some types of polyembryony haploid embryos are formed, such as in Linum.
