Salivary proline-rich protein may reduce tannin-iron chelation: a systematic narrative review

Nutrition & Metabolism, 2017
Background Tannins are often cited for antinutritional effects, including chelation of non-heme iron. Despite this, studies exploring non-heme iron bioavailability inhibition with long-term consumption have reported mixed results.

Hydrolyzable tannins from Balanophora polyandra

Acta Pharmaceutica Sinica B, 2013
AbstractThis study reports an investigation of the chemical constituents of Balanophora polyandra Griff. Fifteen compounds were isolated by column chromatography on silica gel, Toyo-pearl HW-40C, Sephadex LH-20 and by HPLC. Their structures were elucidated as 1,4-di-O-galloyl-2-O-[(E)-p-coumaroyl]-β-D-glucopyranose (1), 1-O-galloyl-β-D-pyranglucose (2),

Effect of Hydrolyzable Tannins on Glucose-Transporter Expression and Their Bioavailability in Pig Small-Intestinal 3D Cell Model

Molecules, 2021
Intestinal transepithelial transport of glucose is mediated by glucose transporters, and affects postprandial blood-glucose levels. This study investigates the effect of wood extracts rich in hydrolyzable tannins (HTs) that originated from sweet chestnut
