Journal ArticleDOI
Vitamin E (α- and γ-Tocopherol) Levels in the Community: Distribution, Clinical and Biochemical Correlates, and Association with Dietary Patterns
Sabina Waniek,Romina di Giuseppe,Tuba Esatbeyoglu,Sandra Plachta-Danielzik,Ilka Ratjen,Gunnar Jacobs,Ute Nöthlings,Manja Koch,Manja Koch,Sabrina Schlesinger,Sabrina Schlesinger,Gerald Rimbach,Wolfgang Lieb +12 more
TL;DR: Assessment of the distribution and determinants of circulating vitamin E levels in a German population found a dietary pattern rich in meat, bread, fats, potatoes, and sugar/confectionery was inversely related to α-tocopherol levels.
Journal ArticleDOI
Dimeric procyanidins: screening for B1 to B8 and semisynthetic preparation of B3, B4, B6, And B8 from a polymeric procyanidin fraction of white willow bark (Salix alba).
TL;DR: White willow bark has been used for the semisynthetic formation of dimeric procyanidins B3, B4, B6, and B8 and the reaction mixtures of the Semisynthesis were successfully fractionated with high-speed countercurrent chromatography (HSCCC).
Journal ArticleDOI
Biochanin A and prunetin improve epithelial barrier function in intestinal CaCo-2 cells via downregulation of ERK, NF-κB, and tyrosine phosphorylation.
Stefanie Piegholdt,Kathrin Pallauf,Tuba Esatbeyoglu,Nancy Speck,Karina Reiss,Lars Ruddigkeit,Achim Stocker,Patricia Huebbe,Gerald Rimbach +8 more
TL;DR: Both biochanin A and prunetin were identified as potent reducers of NF-κB and ERK activation, zonula occludens 1 tyrosine phosphorylation, and metalloproteinase-mediated shedding activity, which may account for the barrier-improving ability of these isoflavones.
Journal ArticleDOI
Chemical Characterization, Free Radical Scavenging, and Cellular Antioxidant and Anti-Inflammatory Properties of a Stilbenoid-Rich Root Extract of Vitis vinifera.
Tuba Esatbeyoglu,Philipp Ewald,Yoshiaki Yasui,Haruka Yokokawa,Anika E. Wagner,Seiichi Matsugo,Peter Winterhalter,Gerald Rimbach +7 more
TL;DR: The data suggest that the root extract of Vitis vinifera exhibits free radical scavenging as well as cellular antioxidant and anti-inflammatory properties.
Journal ArticleDOI
Phenolic Composition, Radical Scavenging Activity and an Approach for Authentication of Aronia melanocarpa Berries, Juice, and Pomace.
TL;DR: Aronia pomace, a valuable by-product of juice production, showed the highest phenolic content and possessed the highest radical scavenging activity, according to the TEAC (Trolox® equivalent antioxidant capacity) assay.
