有關黃烷醇抗氧化能力...

Question

The in vitro spiking of
a pooled plasma sample showed that a plasma polyphenol concentration
of 7.5 mol/L was necessary to cause an increase in
the antioxidant activity. The mean maximal plasma concentration
of total flavanols was 1.2 mol/L. This showed that the
increase in plasma flavanol concentration was not high enough to
cause an increase in the antioxidant capacity.
在試管內用大釘釘牢
顯示那的一個集中的等離子樣品等離子多酚集中
7.5個中 _ 克分子/ L 必要引起一的增加
抗氧化劑活動。 卑鄙的最大的等離子集中
總數個中，flavanols _ 1.2 _ 克分子/ L。 這顯示那
在等離子增加集中不夠高的flavanol
引起抗氧化劑能力的增加。

This small increase
in plasma antioxidant activity might be due to flavanol metabolites
or degradation products.
這個小的增加
用等離子抗氧化劑活動可以由於flavanol代謝物
或者墮落產品。

Answer 1

The in vitro spiking of a pooled plasma sample showed that a plasma polyphenol concentration of 7.5 μmol/L was necessary to cause an increase in the antioxidant activity.
以試管中添加介入物質的分式所做的實驗顯示﹕血中多酚濃度必須達到 7.5 μmol/L才能造成抗氧化活性的開始上升。

The mean maximal plasma concentration of total flavanols was 1.2 μmol/L.
但{接受實驗者}平均最高血中總黃烷醇濃度只有1.2 μmol/L.

This showed that the increase in plasma flavanol concentration was not high enough to cause an increase in the antioxidant capacity.
這表示{僅飲用或服用一個劑量所}增加的血中黃烷醇濃度是不足以導致抗氧化能力的增加。

metabolitesor degradation products.
{較低的血中黃烷醇濃度}之所以不易增加血中抗氧化活性可能是由黃烷醇代謝物或其降解物質所導致。
