酚类

To get full health benefits from tea, however, don't use milk in it - some casein-related proteins in the milk bind the polyphenols - but instead acidify it with a little lemon (or even take your vitamin C with the tea) to enhance absorption of the tea polyphenols.

获得全面的健康的好处，从茶叶，不过，不要使用牛奶在它-一些酪蛋白相关蛋白的牛奶约束，多酚类物质-而是酸化，它与少许柠檬（或什至采取您的维生素C与茶）加强吸收的茶多酚。

The characteristics of 4-nitrophenol's λmax and εmax supply evidence that nitro is a better auxochrome for phenol derivatives.

对硝基酚的λmax和εmax的特性研究表明—NO2是酚类化合物较好的助色基。

The paper also studied the antioxidation capacity of soybean peptides in the food system and non-food system. The results showed that the soybean peptides can prolong the inducing period of the axunge oxygenation and cooperate with hydroxybenzene antioxidant which was more obvious in the food system. In the non-food system, the soybean peptides can control the autooxidation speeds of octadecadienoic acid and diphenolic compound and the effect on the latter was more obvious.

论文对大豆多肽在食物体系与非食物体系中的抗氧化性能做了研究，结果表明：大豆多肽在食物体系中能够延长油脂氧化酸败的诱导期，而且与酚类抗氧化剂协同作用，效果更为明显；在非食物体系中，大豆多肽能够抑制亚油酸的自氧化及邻苯三酚的自氧化速率，其中对后者的抑制作用较前者显著。

At least two separate inhibitory actions on 5-HT3A receptors could be identified for propofol, whereas the enhancing action seen for the two related smaller phenol derivatives could no longer be detected. 5-HT-dependent and 5-HT-independent interactions could be distinguished for all three drugs.

异丙酚被证实对5-HT3A 受体至少有两种相互独立的作用，而在两种相关的较小分子的酚类衍生物中所看到的增强作用则不能被检测到。5-HT 依赖和5-HT 非依赖两种相互作用因为这三种药物而著称。

However, the presence of steric hindrance and electron-withdrawing groups on the benzene ring would decrease the activity of phenols.

苯环上有供电子基团的酚类化合物反应活性比较好，而钝化基团的存在，则会降低酚羟基的反应活性。

The objective of present study aims to reveal the adaptive natuer of these metabolistes in nectar in biocoenosis context by analyzing the behavioral and physiological mechanisms of how bees cope with secondary compounds in nectar. The results are as following.

本文通过对取食含有次生代谢物质花蜜的蜜蜂的行为、生理和性别分化的研究，来探讨花蜜中这些次生代谢物质在自然群落中的生态功能，主要的研究结果如下： 1、野坝子植物分泌的花蜜中含有酚类化合物，其相对涩性（多酚对植食性动物取食阻隔大小的参数）为0.1679±0.0467。

With 8 kinds of polyphenols as the substrate, the change of polyphenol oxidase activity in different carambola cultivars and during their storage was determined by spectrophotometer method.

方法］以8种酚类物质作底物，采用分光光度计法测定不同杨桃品种果实及其贮藏过程中多酚氧化酶活性的变化情况。

With 8 kinds of polyphenols as the substrate, the change of polyphenol oxidase activityin different carambola cultivars and during their storage was determined by speetrophotometer method.

方法以8种酚类物质作底物，采用分光光度计法测定不同杨桃品种果实及其贮藏过程中多酚氧化酶活性的变化情况。

Actually, consider to make clear, deposit time little the new tea at a month, contain the more much phenol without oxidation kind, aldehyde kind with alcohol kind material, the generation of meeting gastric bowel mucous membrane to human body spurs action strongly, cause the symptom such as abdominal distension, bellyacke.

其实，研究表明，存放时间少于一个月的新茶，含有较多的未经氧化的多酚类、醛类和醇类物质，会对人体的胃肠粘膜产生强烈刺激作用，引起腹胀、腹痛等症状。

Other phenolic compounds found in tea even greater concentration than the flavonols are the flavanols.

茶叶中存在的比黄酮醇类物质浓度更高的其它酚类化合物是黄烷醇类物质。
