Inhibition of scopolamine‐induced memory and mitochondrial impairment by betanin
Journal of Biochemical and Molecular Toxicology, 2022AbstractMitochondrial dysfunction and oxidative stress are identified to contribute to the mechanisms responsible for the pathogenesis of Alzheimer's disease (AD). Scopolamine (SCO) as a potent drug for inducing memory and learning impairment is associated with mitochondrial dysfunction and oxidative stress.

New Pathways of Betanidin and Betanin Enzymatic Oxidation
Journal of Agricultural and Food Chemistry, 2011Betanidin is a basic betacyanin with a 5,6-dihydroxyl moiety which causes its high antioxidant activity. For the purpose of structural study, the enzymatic oxidation of betanidin and betanin (5-O-glucosylated betanidin), followed by chromatographic separation of the oxidation products with spectrophotometric and mass spectrometric detection (LC-DAD-MS ...

Die Struktur des Betanins. 7. Mitteilung. Über die Konstitution des Randenfarbstoffes Betanin
Helvetica Chimica Acta, 1965AbstractIt is shown that the glucose residue in betanin is attached at the 5‐hydroxyl group (structure 2): Treatment of betanin with diazomethane, acidic hydrolysis and acetylation afforded 5‐O‐acetyl‐6‐O‐methyl‐neobetanidin trimethylester (9), which was cleaved by alkali. The cleavage product was esterified with methanol and oxydized by means of FRÉMY

Photochemial Degradation of Betanine and Selected Anthocyanins
Journal of Food Science, 1981ABSTRACT The effect of fluorescent light on the degradation rates of betanine and the major cranberry anthocyanins was determined in model systems. Degradation rates were measured in the presence of oxygen in a temperature range 25–55°C. Retained pigment was separated and quantified by high performance liquid chromatography. Light had

The neuroprotective effect of betanin in trimethyltin-induced neurodegeneration in mice
Metabolic Brain Disease, 2020Betanin, a natural food colorant with powerful antioxidative properties, has not been studied in terms of neurodegenerative disease intervention. Therefore, the present study aimed to investigate the neuroprotective effects of betanin against trimethyltin chloride (TMT) -induced neurodegeneration in mice.

Influence of water activity on the stability of betanine
Zeitschrift f�r Lebensmittel-Untersuchung und -Forschung, 1990The influence of water activity on the stability of betanine isolated using Sephadex G-25 and crystallized with 0.1% HCl was investigated. The influence of water activity was studied in water/glycerol model systems with water activities ranging from 0.37 to 1.00 at 75° C.

Occurrence, chemistry and application of betanin
Food Chemistry, 1980Abstract Anthocyanins and betalaines are mutually exclusive in plants. The chief red pigment of beetroot is betanin. Its extraction gives low yield and a large proportion of sugar. This may be removed by aerobic fermentation. The chemistry of betanin and the synthesis of betanidin are described.

Effect of pH on the Degradation and Regeneration of Betanine
Journal of Food Science, 1987ABSTRACT The influence of pH (3.0–7.0) on betanine stability in solution was studied based on proposed reversible reaction kinetics. The forward and reverse rate constants and their activation energies were determined and found to be pH dependent.

The conversion of betanidin and betanin to neobetanindin derivatives
Tetrahedron, 1967Abstract Details are given for the conversion of betanin, the pigment of the red beet, and its aglucone, betanidin, to a number of derivatives of neobetanidin trimethyl ester. The conversion occurred, presumably by air-oxidation, when the basic conjugated system was deprotonated under the influence of diazomethane, pyridine and acetic anhydride ...

LYCOPENE AND BETANINS BASED HERBAL LIPSTICK
INDIAN DRUGS, 2019Colouring the skin particularly skin of face or lips, is an ancient practice going back to prehistoric times. The use of such coloring products has increased and the choice of shades of colour, texture and luster have changed and become wider. The present study was aimed at formulation and evaluation of a lipstick using herbal colouring agent.
