Journal ArticleDOI
Curcumin—From Molecule to Biological Function
TL;DR: This Review describes the development of curcumin from a "traditional" spice and food coloring to a "modern" biological regulator.
Journal ArticleDOI
Betanin—A food colorant with biological activity
TL;DR: Betanin is a scavenger of reactive oxygen species and exhibits gene-regulatory activity partly via nuclear factor (erythroid-derived 2)-like 2-(Nrf2) dependent signaling pathways, and may induce phase II enzymes and antioxidant defense mechanisms.
Journal ArticleDOI
Free radical scavenging and antioxidant activity of betanin: electron spin resonance spectroscopy studies and studies in cultured cells
Tuba Esatbeyoglu,Anika E. Wagner,Rouhollah Motafakkerazad,Yu Nakajima,Seiichi Matsugo,Gerald Rimbach +5 more
TL;DR: Present data suggest that betanin is both a free radical scavenger and an inducer of antioxidant defense mechanism in cultured cells.
Journal ArticleDOI
Free Radical Scavenging and Cellular Antioxidant Properties of Astaxanthin.
Janina Dose,Seiichi Matsugo,Haruka Yokokawa,Yutaro Koshida,Shigetoshi Okazaki,Ulrike Seidel,Manfred Eggersdorfer,Gerald Rimbach,Tuba Esatbeyoglu +8 more
TL;DR: The electron spin resonance (ESR) and spin trapping data suggest that synthetic astaxanthin is a potent free radical scavenger in terms of diphenylpicryl-hydrazyl (DPPH) and galvinoxyl free radicals.
Journal ArticleDOI
Comparative biokinetics and metabolism of pure monomeric, dimeric, and polymeric flavan‐3‐ols: A randomized cross‐over study in humans
Stefanie Wiese,Tuba Esatbeyoglu,Peter Winterhalter,Hans-Peter Kruse,Stephanie Winkler,Achim Bub,Sabine E. Kulling +6 more
TL;DR: 5-(3',4'-dihydroxyphenyl)-valerolactone represents an important in vivo metabolite of (-)-epicatechin and procyanidin B1 produced by the gut microbiota, and is associated with beneficial health effects in humans.
