Dietary Antioxidants

Antioxidants protect biological systems from oxidative damage produced by oxygen-containing free radicals and from redoxactive transition metal ions such as iron, copper, and cadmium.

膳食抗氧化剂

抗氧化剂可保护生物系统免受含氧自由基和氧化还原过渡金属离子（如铁、铜和镉）引起的氧化损伤。

In vivo bioavailability, absorption, excretion, and pharmacokinetics of [14C]procyanidin B2 in male rats.

Stavroula Stoupi et al.

Drug metabolism and disposition: the biological fate of chemicals, 38(2), 287-291 (2009-11-17)

Procyanidins are important biologically active compounds, but the pathway and extent of absorption and metabolism are controversial. We conducted a mass balance study to evaluate the total radioactivity excreted in urine and feces after oral administration of [(14)C]procyanidin B2 to

Intake of dietary procyanidins does not contribute to the pool of circulating flavanols in humans.

Javier I Ottaviani et al.

The American journal of clinical nutrition, 95(4), 851-858 (2012-03-02)

Accumulating data show a causal role for flavanols in the mediation of cardiovascular benefits associated with the consumption of flavanol- and procyanidin-containing foods. Evidence for a direct causal role for procyanidins in this context is far less profound due to

A comparison of the in vitro biotransformation of (-)-epicatechin and procyanidin B2 by human faecal microbiota.

Stavroula Stoupi et al.

Molecular nutrition & food research, 54(6), 747-759 (2009-11-28)

The catabolism by human faecal microbiota of (-)-epicatechin (1) (2, 3-cis stereochemistry) and its dimer pure procyanidin B2 (2), has been compared using a static in vitro culture model. The catabolites were characterised by LC-MS(n), UV absorption and relative retention
