Additional, in new tea not the much phenol of classics oxidation kind material and aldehyde kind corporeal content is more, have very intense stimulative effect to gastric bowel mucous membrane, the person with gastric bowel poorer function especially patient of inflammation of path of chronic stomach bowel, drink new tea easy cause gastral cavity aching, bilge the symptom such as full, constipation, mouth doing.

另外，新茶中不经氧化的多酚类物质和醛类物质含量较多，对胃肠黏膜有很强烈的刺激作用，胃肠功能较差的人特别是慢性胃肠道炎症患者，喝新茶易引起胃脘疼痛、胀满、便秘、口干等症状。

Several anti-tumor cell lines and carbonic anhydrase Ⅱ model were established. More than 10000 compounds and extracts from plants were screened using these models and about 10 compounds showed strong inhibitory activities. Two species of plants Inula helianthus-aquatica and Saussurea deltoidea were chosen to investigate chemical and bioactivity constituents based on the results of screening of extracts and fractions. 58 compounds were isolated and identified from these two plants, 6 compounds were found to be new and 14 compounds showed anti-tumor activities. We also studied the anti-tumor mechanism of the compound bigelovin isolated from Inula helianthus-aquatica. Bigelovin was found with apoptotic activity against cell line U266 by lowering the amount of important transcription factor E2F-1 which inhibits the cell cycle at G0/G1 stage. Docking study on 7 natural new phenolic inhibitors of CA Ⅱ and 3D-QSAR study on 61 sulfonamide inhibitors of CA Ⅱwere also investigated. The calculated results were in good correlation with experimental results.

基于以上两种重要疾病和研究组方向，本论文工作开展了多个肿瘤细胞株和碳酸酐酶Ⅱ靶标模型的建立和筛选工作，累计筛选1万多个/次样品，发现10余个活性较强化合物；从粗提取物筛选结果中选取两种抗肿瘤活性强的菊科植物水朝阳旋覆花(Inula helianthus-aquatica)和三角叶凤毛菊进行了系统化学和活性成分研究，分离鉴定了58个化合物，发现6个新化合物和14个抗肿瘤活性化合物；通过合作对水朝阳旋覆花中活性较强的bigelovin进行了抗肿瘤作用机制研究，发现它可能是通过降低G2期重要的转录因子E2F-1，致使细胞周期阻滞在G0/G1期，引起多发性骨髓瘤U266细胞凋亡；开展了7个新的天然酚类CAⅡ抑制剂的对接研究和61个合成的系列磺酰胺类CAⅡ抑制剂的3D-QSAR分析，结果表明计算与实验一致。

First, the results showed that the branch had the highest phenolic content, and the leaf had the highest flavonoid content among four parts of Morus alba.

结果发现在桑的四个药用部位中总多酚类含量以桑枝最多，黄酮类含量则以桑叶较多。

Anthocyanins are plant unique phenolic compounds derived from flavonoid biosynthetic pathway. The red cyanidins, orange pelargonidin, and purple-blue delphinidin are three major anthocyanins, which are reported to have anti-oxidative activity on lipid and scavenge activity on removing free radical.

花青素是植物所特有的多酚类化合物，也是类黄酮代谢路径所衍生的化合物，植物主要的花青素有紫红色的矢车菊素、橘红色的天竺葵素及蓝紫色的飞燕草素等三种，均为抗氧化物，可抑制脂质过氧化，并具有清除自由基的能力。

Quinonyl compounds were reducted to phenolic compounds in high yields promoted by aluminum triiodide ,and after the reaction with dienophiles in Diels Alder reactions concave adductions were combined.

在现场制备的三碘化铝促进下，醌类化合物发生还原反应以良好产率生成酚类物，并且在原位与亲双烯体发生Diels Alder反应从而生成凹状加合

Taxus cell lines were cultured on fresh medium succeedingly at regular intervals andantioxidant such as PVPP was added into culture medium in order to prevent browning of taxuscultured cells.

3红豆杉离体培养细胞在增殖过程中，自身富含的酚类被氧化成醌类物质，导致细胞褐变甚至死亡，在与农杆菌共培养时褐变现象更为严重。

In this study, we determined that the antimutagenic properties of various tea extracts including green, oolong, pu-erh tea, and black tea and six polyphenols include rutin, quercetin, apigenin, gallic acid, umbelliferone, and tannic acid were examined by Ames test which is a widely applied short-term bacterial assay for detecting DNA damage effect of mutagen.

在本篇研究中，我们探讨利用Ames test的方法筛检不同品种茶类包括绿茶、乌龙茶、普洱茶、红茶和数种常见的多酚类化合物包括单宁酸tannic acid、gallic acid、rutin、umbelliferone、apigenin、quercetin对於抑制PhIP（2-amino-1-methyl-6-phenylimidazo(4，5-b)pyridine）和 2-AAF（2-Acetylaminofluorene）两种致突变剂的抗突变作用。

The effects of various antioxidants on the discoloring behavior and the mechanical properties of the PA6 specimens during the course of thermal-oxidative aging were systematically studied.

研究结果表明：使用胺类抗氧剂能明显地改善PA6的抗热氧老化变色性能，还能使其保持较高的热稳定性能和力学性能，并大大延长PA6的静态使用寿命；用酚类抗氧剂/亚磷酸酯抗氧剂组成（1：1）的稳定体系能对改善PA6的耐热氧老化性能产生协同效应。

The method adopts powders (10.0 parts of mass) of crop straws and phenols or polyalcohol compound (10 to 100 parts of mass) which is firstly pre-heated by 10 to 30 minutes under a temperature of 30 to 200 DEG C with the effect of acid catalyst (0.5 to 10 parts of mass) for a reaction of 30 to 240 minutes; after the reaction, the compound is washed, neutralized, filtered and dried to obtain a solid appearing as a color from citron yellow, yellow, bight brown to seal brown; wherein, the solid includes 64.0 to 70,0 percent of fibrin and 4.1 to 7.6 percent of lignin.
