Structural Effects on the Antioxidant Properties of Amino Acid Betaxanthins

open access: yesAntioxidants, 2022
Betaxanthins are natural products with high antioxidant and anti-inflammatory properties. Here, we describe the semisynthesis of twenty-one betaxanthins derived from proteinogenic amino acids, including the elusive betaxanthin of l-cysteine and two ...

Betaxanthin Profiling in Beta vulgaris Leaves and Gymnocalycium mihanovichii Grafted Cacti: A Comprehensive Study

open access: yesPolish Journal of Food and Nutrition Sciences, 2023
This study was focused on the identification and quantification of betaxanthins using high-performance liquid chromatography with a diode array detector coupled to electrospray ionisation mass spectrometry (HPLC-DAD-ESI-MS) in leaves of various cultivars

A betaxanthin-based visible and fluorescent reporter for monitoring plant transformation

open access: yesCrop Journal, 2023
Commonly used reporters rely on a single property, such as the fluorescence of GFP and visible color of anthocyanins, therefore these reporters hardly handle the complicated condition in practice.

Betaxanthin Profiling in Relation to the Biological Activities of Red and Yellow Beta vulgaris L. Extracts

open access: yesMetabolites, 2023
Beta vulgaris L. is an edible plant with health-beneficial activities. The profile of betaxanthins is more complex than previously described in beetroot cultivars. Twenty-four betaxanthins were detected in extracts of the peel and flesh of five cultivars

Amino Acid Betaxanthins: Absorption, Fluorescence, And Stability. [PDF]

open access: yesJ Nat Prod
Betaxanthins are natural pigments responsible for the vivid yellow coloration and intrinsic fluorescence of flowering succulent plants within the order Caryophyllales. Though less extensively studied than other plant pigments classes, betaxanthins hold potential for application as safe food dyes, solar cell absorbers, antioxidants, and genetically ...

Dynamics of changes in the content of betalain pigments in red beet roots during the growing season and storage

open access: yesОвощи России, 2023
Purpose. Betalains, plant pigments of red beet roots, exhibit antioxidant activity and reduce the risks of many pathological conditions. However, the widespread introduction of betalains is hampered by insufficient knowledge of their transformations ...

The Decisive Step in Betaxanthin Biosynthesis Is a Spontaneous Reaction1 [PDF]

open access: yesPlant Physiology, 1999
Abstract Experiments were performed to confirm that the aldimine bond formation is a spontaneous reaction, because attempts to find an enzyme catalyzing the last decisive step in betaxanthin biosynthesis, the aldimine formation, failed. Feeding different amino acids to betalain-forming hairy root cultures of yellow beet (Beta vulgaris L.

Identification of <i>CqCYP76AD5v1</i>, a gene involved in betaxanthin biosynthesis in <i>Chenopodium quinoa</i>, and its product, betaxanthin, which inhibits amyloid-β aggregation. [PDF]

open access: yesPlant Biotechnol (Tokyo)
Betalain pigments, primarily produced by the order Caryophyllales, are categorized into betacyanins (red/purple) and betaxanthins (yellow/orange). While the biosynthetic pathways of these pigments are well-studied, the genes responsible for betaxanthin biosynthesis in quinoa were previously unknown.

Influence of vacuum microwave drying parameters on the physicochemical properties of red beetroots

open access: yesНауковий вісник Львівського національного університету ветеринарної медицини та біотехнологій імені С.З. Ґжицького. Серія: Харчові технології, 2021
In recent years, the consumption of red beetroots has increased significantly due to its good taste, high nutritional value and abundant active compounds. Red beetroot is prone to spoilage due to its high moisture content, making it perishable.
