酚类

Image recording medium comprising a substrateand an imaging layer containing binder, developer, dye, stabilizer against oil exposure (e.g. Calcium salt of organic acid); method for preparing a recording medium comprising binder, radiation absorber, phenolic compound, calcium salt of organic acid, and leuco dye, said radiation absorber initiating reaction between phenolic compound, calcium salt of organic acid and leuco dye.

图像记录介质，其包含衬底和成像层，所述成像层包含粘合剂、显色剂、染料、抵抗油暴露的稳定剂；制备包含粘合剂、辐射吸收剂、酚类化合物、有机酸的钙盐和无色染料的记录介质的方法，所述辐射吸收剂引发酚类化合物、有机酸的钙盐和无色染料之间的反应。

5Water soluble phenolic substances in female tree leaves of Acer negundo L.wereconstantly more than those of male tree leaves in about the entire growing season(p＜0.01),whichindicated the close correlation between plant sex and concentration of the phenolic substances.

5复叶槭雌株叶片水溶性酚类物质的含量在整个生长季中几乎始终高于雄株，方差分析表明差异显著(p＜0.01)，反映复叶槭植株的性别与其叶片中水溶性酚类物质的含量显著相关。

Since the relative antioxidant capacity of all the phenolic compounds was much higher than trolox in both assays, it is a good indication that phenolic compounds possess high antioxidation capacity against peroxy radicals.

由於酚类物质之相对抗氧化力均远高於trolox，表示酚类物质对过氧自由基具有很好的抗氧化效果。

This indicated that CH1 could induce resistance of cucumber to Pythium aphanidermatum by increasing its enzymes activities of phenolic metabolism.

说明CH1是通过提高黄瓜植株体内酚类物质代谢的酶活性来激发酚类物质的积累，从而诱导黄瓜对猝倒病产生抗性。

Polyphenols and antioxidant capacity in different organs of Muscat Hamburg in the whole growth periods, and the effects of seedlessness treatment on polyphenols and antioxidant capacity of Muscat Hamburg were studied. The main results are as follows: 1. From the beginning of blooming period to the ripening period of Muscat Hamburg, the content of polyphenols in different organs decreased at first, and then increased with the development of the grape berry.

本文以玫瑰香葡萄为材料，研究了整个生长发育期内葡萄各个器官及无核处理葡萄的酚类物质及抗氧化能力变化，主要结果如下： 1从玫瑰香葡萄始花期开始，至浆果成熟期止，随着果实的发育，葡萄内各个器官的酚类物质含量呈现先下降后上升的趋势。

But both 20 years and 2 years old of pu-erh tea extracts show a strong inhibitory effects against 2-AAF. In addition, tannic acid, gallic acid, rutin, umbelliferone, and quercetin exhibited stronger antimutagenicities against PhIP than apigenin; while all of these polyphenols displayed inhibitory effect against 2-AAF.

而比较数种多酚类化合物发现，tannic acid、gallic acid、rutin、umbelliferone和quercetin对於抑制PhIP的抗突变作用比apigenin来的有效，但是apigenin和其他多酚类化合物对於抑制2-AAF的抗突变作用则均具有明显的抑制效果。

Four phenolic components of p-hydrobenzoic, vanillic, gallic acid and ferulic acids could be detected in soil with different continuous cropping years.

其中棉花秸秆中的酚类化感物质含量高于根系分泌物中的，棉花秸秆地上部酚类化感物质含量高于地下部。

The scavenging effect of polyphenols extracted from grape seeds such as monomers, dimers and trimers on superoxide and hydroxyl radicals is studied with the ESR spin trapping method. The results are comparable with those obtained from chemiluminescence method. It has been proved that polyphenols extracted from grape seeds have a strong scavenging effect on Oxygen free radicals. Probably this is the reason why drinking some grape wine every day is good for one's health.

用ESR自旋捕集技术研究了从葡萄籽分离的单体、二聚体和三聚体等多酚类物质对羟基自由基和超氧阴离子的精除作用，并与化学发光法的测定结果进行了比较，得到了较一致的结果，证明葡萄籽中多酚类物质对氧自由基的确有较好的清除作用，这很可能是喝少量葡萄酒有利于身体健康的原因。

But some academician considers that phenols are not the cause of soil degradation, in contrast, some of phenols afford protection to the growth of plants.

而一些学者认为，酚类物质并不是引起地力衰退的主要原因，相反，某些酚类物质对植物的生长具有保护作用。

Solid part of the wine brought is not only pigment, but also with the pigment to bring the same wine as the phenolic compounds with tannin, the deeper the color of wine, its composition by the pigment and tannin content of phenolic substances increased.

固体部分带给葡萄酒的不仅是色素，同时带给葡萄酒的还有与色素一样同为酚类物质的丹宁，葡萄酒的颜色越深，其由色素和丹宁构成的酚类物质的含量也越高。
