Impact of betacyanins on responses to ultraviolet radiation in Amaranthus tricolor L.

Journal of Plant Interactions, 2020
Relatively little is known about the physiological significance of betalain pigments. To investigate a possible protective role for betalains (betacyanin), from UV-B irradiation, two cultivars of A.

Uncovering the Key Factors Influencing Phytochemical and Phytopharmacological Properties During Medicinal Plant Processing

eFood, Volume 7, Issue 1, February 2026.
From farm to pharma, this review details the engineering of quality in medicinal plants through a science‐driven approach: it first elucidates how genetic and environmental factors inscribe the plant's phytochemical and phytopharmacological profile before harvest, and then dissects the postharvest techniques and technologies—chemical and thermal pre ...

Stability of encapsulated red dragon fruit (Hylocereus polyrhizus) peel: effects on antioxidant and prebiotic potency

Advances in Food Science, Sustainable Agriculture, and Agroindustrial Engineering
The high consumption of red dragon fruit has led to an increase in red dragon fruit peel waste in the environment, which has potential as a source of natural food coloring and as a prebiotic but is susceptible todegraded.

Beetroot Extract Encapsulated in Inulin: Storage Stability and Incorporation in Sorbet

Chemical Engineering Transactions, 2017
Betacyanin is a natural colorant extracted, principally, by beetroot, being a good alternative to substitute synthetic colorant, because it not shows toxic effect and established daily intake rate.

A modifiedAmaranthus betacyanin test for cytokinin bioassay

Biologia Plantarum, 1975
A modified procedure for the extraction of betacyanin fromAmaranthus seedlings is described. Application of this modification increased the absorbance of cytokinin-treatedAmaranthus explants in most cases. The modifiedAmaranthus test is compared with the soybean callus test in the bioassay of kinetin, 6-benzylaminopurine, and 6(δ,δ-dimethylallyl ...

Pollinator, herbivore, and climatic selective pressures differ across a floral color transition zone

American Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise Spatial and temporal variations in climate and ecological interactions may underlie the origin and maintenance of floral color polymorphisms across a species range. Betalains are nitrogen‐containing, phylogenetically restricted pigments that, like the widespread and well‐studied anthocyanins and carotenoids, may attract pollinators ...
