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 ...

Betalains: A Narrative Review on Pharmacological Mechanisms Supporting the Nutraceutical Potential Towards Health Benefits

Foods
Betalains are naturally occurring pigments sourced mainly from Beta vulgaris (beetroot), Hylocereus spp. (dragon fruit), Amaranthus spp., and Opuntia spp. Betalains are widely used for their vibrant colors and health-promoting properties.

Semisynthesis of Betaxanthins from Purified Betacyanin of Opuntia dillenii sp.: Color Stability and Antiradical Capacity. [PDF]

Molecules
The availability of pure individual betalains in sufficient quantities which permit deeper understanding is still a challenge. This study investigates the high-yielding semisynthesis of betaxanthins using betalamic acid from a natural source (Opuntia dillenii), followed by condensation with ʟ−amino acids and further purification.

Virtual Screening of Phytochemicals From Medicinal Plants as Promising PDE5 Inhibitors Against Erectile Dysfunction

Food Science &Nutrition, Volume 14, Issue 2, February 2026.
Phytochemicals from Algerian medicinal plants were virtually screened as potential phosphodiesterase‐5 (PDE5) inhibitors for erectile dysfunction therapy. Drug‐likeness and toxicity analyses identified catechin, ellagic acid, and rosmarinic acid as safe, bioavailable candidates.

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 ...
