EGC.EC.EGCG...的曲線圖解說..有點不懂

Question

FIGURE 4. Trolox equivalent (TE) values of pooled plasma to which
different concentrations of ()-epigallocatechin (EGC), ()-epicatechin
(EC), ()-epigallocatechin-3-gallate (EGCG), ()-epicatechin-3-gallate
(ECG), or a mixture of the 4 flavanols were added (A) or to which the same
concentrations of the flavanols were added (B). Values are the mean (<+->SEM)
of 3 determinations per time point. Antioxidant activity was determined by
using the trolox equivalent antioxidant capacity assay, which measured the
reduction in the radical cation 2,2'-azinobis-(3-ethylbenzothiazoline-6-
sulfonic acid) diammonium salt.

Answer 1

FIGURE 4. Trolox equivalent (TE) values of pooled plasma to which different concentrations of (–)-epigallocatechin (EGC), (–)-epicatechin (EC), (–)-epigallocatechin-3-gallate (EGCG), (–)-epicatechin-3-gallate (ECG), or a mixture of the 4 flavanols were added (A)
圖4A﹕這是一份顯示將各種黃烷醇(EGC﹑EC﹑EGCG﹑ECG﹑上述4者的混合)以不同的濃度添加入匯集的血漿後得到的TE值曲線
or to which the same concentrations of the flavanols were added (B).
圖4B﹕同圖4A﹐除了添加物的濃度相同。

TE=Trolox equivalent=Trolox 等效=相當於多少Trolox的抗氧化能力的意思﹔Trolox 是一種類似維他命E的抗氧化物﹐常被用來當做其待測抗氧化物的比較標準。假設測出的TE=2.5﹐表示此待測物的抗氧化能力是Trolox的兩倍半

Values are the mean (<+->SEM)of 3 determinations per time point.
每個時間點上的數值是以三份樣本的測定值平均後的結果(含標準平均誤差)
Antioxidant activity was determined by using the trolox equivalent antioxidant capacity assay,
採用"Trolox 等效抗氧化能力分析法"來測定抗氧化活性
which measured the reduction in the radical cation 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt.
該分析法以測量ABTS氧離子自由基的減少程度來代表抗氧化能力

對照圖4與其文字說明後﹐我覺得有矛盾存在(濃度相同或不同沒有在圖中予以區分)﹐如果你要做簡報﹐建議選擇圖4B配上4A的文字比較吻合文章中所有提到圖4的論述。

更正：是陽離子, 不是氧離子.
