Results IC50 that catechin eliminated O(superscript - subscript 2) and OH was 6.16, 0.59 g/mL respectively, and the eliminating ability of catechin was much stronger than that of the extract from liquorice, rosemary, grape pip, giant knotweed and ginkgo leaf.

结果：儿茶素清除O(上标-下标 2)与OH的IC50分别为6.16，0.59μg/mL，明显优于甘草提取物、迷迭香提取物、葡萄籽提取物、虎杖提取物及银杏叶提取物。

Four different catechin content cultivars were selected from our tea germplasm appraisal database to assay the gene expression level of the seven genes, flavonol synthase, dihydroflavonol-4-reductase, leucoanthocyanidin reductase, anthocyanidin synthase, etc, which were involved in the flavonoids biosynthesis. The result showed that, the DFR and LAR transcripts were expressed increased with the increasing of tea catechin contents. Nevertheless, the others did not show this tendency clearly.

利用半定量PCR技术检测总儿茶素含量不同的4个茶树品种中与类黄酮合成相关的黄酮醇合成酶、二氢黄酮醇－4-还原酶、无色花色素还原酶、花色素合成酶等7个基因的表达情况，结果表明DFR和LAR基因的表达量与茶树中总儿茶素含量呈一定的相关性，而其他基因则与其相关性不大。

These include catechin and gallocatechin (hydroxyls at positions 5' as well as at 3' and 4' as in catechin), their esters with gallic acid, catechin gallate, and gallocatechin gallate, and their epimers.

它们有几茶素和儿茶素(在5'位上以及如同儿茶素中一样在3'和4'位上羟基化)，它们与酸生成的酯，即儿茶素酸酯和儿茶素酸酯，以及它们的差向异构体。

The ethanol extract of tamarillo fruit contained a high content of phenolic compounds [ 28.8 ± 0.05 mg catechin equivalents/g dry weight ] and showed a strong DPPH (1,1-diphenyl-2-picrylhydrazyl) scavenging activity [ IC50 = 189.1 ± 1.3 μg/mL ].

树番茄乙醇粗萃物含有高量的酚类化合物 [ 28.8 ± 0.05 mg catechin equivalents/g dry weight ]，并表现出强的DPPH（1，1-diphenyl-2- picrylhydrazyl）自由基清除能力 [ IC50 =189.1 ± 1.3 μg/mL ]。

Following a 12-hour fast, each subject orally ingested a green tea extract tablet containing 245mg of catechin (82mg epigallocatechin gallate, EGCg), which delivered catechin levels comparable to two cups of green tea.

经过12小时的禁食，每位研究对象口服一粒含有245毫克儿茶素(82毫克EGCg)的绿茶补充剂，相当於约两杯绿茶所含有的儿茶素份量。60分钟后，研究对象之EGCg浓度明显增加约267%，而EGCg及PCOOH之浓度净变化则显示反比关系(r=0.52，p.05)。
