方法利用丹参中水溶性酚酸类成分与亚硝酸钠和硝酸铝溶液在碱性条件下的显色反应，比色法测定该两种制剂中水溶性酚酸的总量。结果原儿茶醛在3.336~14.46mg/L范围内呈良好的线性关系，回归方程为：A=0.02777C+0.01279(r=0.9996)，加样平均回收率为100.8%，RSD为0.96%。结论该法简便快速，结果准确，重现性好，可用于该制剂的质量控制。

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。

When oxygen is present in cells, polyphenol oxidase enzymes in the chloroplasts rapidly oxidize phenolic compounds naturally present in the apple tissues to o-quinones, colorless precursors to brown-colored secondary products.

当氧存在于苹果组织的细胞中时，叶绿体（含有叶绿素和进行光合作用的地方）中的多酚氧化酶，会迅速地将天然存在于苹果组织中的酚类化合物氧化为邻醌。

The purpose of this work is to develop new methods for syntheses of polyimides derived from chlorophthalic anhydrides.

本工作的目的是以氯代苯酐和二胺为原料，制备双氯代酞酰亚胺单体，然后进行聚酰亚胺合成方法的研究，以达到减少合成步骤，降低其生产成本的目的，主要内容如下： 1由双氯代酞酰亚胺与双酚A在不同体系中进行聚合反应，发现双酚是否完全成盐和聚合体系含水量是决定聚合物分子量的关键因素。

Based on the four steps of risk assessment that is hazard identification,hazard characterization,exposure assessment and risk characterization,the risk assessment of bisphenol A is expound in this paper.The results show the potential human exposure to bisphenol A is negligibl...

根据风险评估理论的四个步骤，即危害鉴定、危害特征描述、暴露评估和风险特征描述，对双酚A进行风险评估，结果表明人体暴露于双酚A的量是微不足道的，没有对人体健康构成已知的风险。

Most sugars, organic acids, phenolic acids and most amino acids increased significantly with elevated CO_2. The treatment, 950±50μmol·mol-1 CO_2 enrichment for 6 h every day had more obvious effects than the treatment, 950±50μmol·mol-1 CO_2 enrichment for 3 h every day. Levan, sucrose, arginine, oxalic acid, alanine, malic acid, acetic acid, lactic acid cinnamic acid,ρ- hydroxybenzoic acid and benzoic acid increased significantly.

CO_2施肥黄瓜根系分泌有机酸、氨基酸、糖和酚酸的总量增加，上、下午均施肥的处理分泌数量最多；CO_2施肥显著促进了果聚糖、蔗糖、草酸、苹果酸、乙酸、乳酸、多数氨基酸、肉桂酸、对羟基苯甲酸和苯甲酸等组分的分泌；单位鲜重根系分泌糖和酚酸的数量增加，多数氨基酸保持不变或降低，但有机酸分泌规律不一致。

Experimental results showed that aerosol created by 1,3,5-trimethylbenzene photooxidation can be classify with five distinct chemical particle classes, the predominant components of these five particles are aromatic aldehyde, phenol, nitrophenol and carboxylic acid compounds.

利用该算法对OH自由基启动1，3，5-三甲苯光氧化形成的二次有机气溶胶单粒子质谱数据进行了聚类分析，在得到的五个聚类中包含了芳香醛、酚类化合物、硝基酚和羧酸等重要的光氧化产物，为研究苯系物光氧化机理提供了新的信息。
