酚类

Methods〕 Volatile phenolics in drinking water not been extracted by chloroform were detected by flow injection analysis.

目的〕为获得一种方便、准确和灵敏测定水中挥发性酚类化合物的检测方法。

Part Two: The effect of fruit extract on CRL-2606 production of PGE2 Effect of anthocyanin rich fruit extracts on endothelial cells'PGE2 production Epidemical experiment shows that phenolics in fruits and vegetables may prevent the occurrence of chronicle cardiovascular heart disease. To investigate the activity of fruit extracts on artery blood vessel cells, we chose CRL-2606 cell line, a normal iliac artery endothelia cells. Using indomethacin as control, we investigate the effect of blueberry extracts, blackcurrant extracts, chokeberry extracts, cyanidin3-glucoside, and malvidin3-glucoside on the PGE2 production of CRL-2606 cells.

第二部分水果提取物对人体细胞系CRL-2606产生PGE2的影响水果提取物对血管内皮细胞释放PGE2的影响流行病学调查表明，蔬菜水果中的多酚类物质具有预防慢性心血管疾病的作用，为研究水果提取物对血管细胞的作用，我们选择回肠动脉内皮细胞CRL-2606细胞系作为研究对象，以indomethacin为对照，研究了blueberry，blackcurrant，chokeberry提取物及cyanidin3-glucoside，和malvidin3-glucoside对血管内皮细胞释放PGE2的影响。

It is very important to promote the development on the field of coal chemistry by studing deeply on the mechanism of phenolic compounds produced during coal prolysis at lower temperature.

深入研究煤低温热解过程中酚类的生成机理具有典型性和代表性，对促进煤化学研究具有重要的意义。

This kind of compound has a selective killing function on the cancer cells.

背景与目的：酚类化合物抗癌研究近年来受到重视。

Polyphenols can not be combined sufficiently the activity of enzyme decreased slowly because of insufficient cellular fragmentation in the processing of blacke tea congou. But the activity of hydrolydase will increase with the damnification of cell. So on the contrary the activity of P -glucosidase continues increasing.

工夫红茶加工过程中，揉捻阶段叶细胞并未充分破碎，使多酚类物质与酶的结合不充分，酶活性下降较少，但细胞损伤，水解酶活性会升高，因而最终结果β-葡萄糖苷酶活性反而继续上升，致使发酵阶段酶活性大于红碎茶，为工夫红茶香气的形成奠定了基础。

The decoloration ratio of cornhusk hydrolysate was 92.27%. 75% of furfurol, 53% of 5-hydroxymethyl furfural and 98% of polyphenol compounds were removed, and the loss of total sugar was below 5%.

在此工艺条件下，水解液的脱色率为92.27%，糠醛脱除率75%，5-羟甲基糠醛脱除率53%，多酚类化合物脱除率98%，总糖损失低于5%。

Alan Crozier, professor of plant biochemistry and human nutrition who led the study, said: Not all fruit juices are the same.

植物生物化学和人类营养教授Alan Crozier领导的研究组称："不是所有果汁都这样的，研究显示不同酚类化合物的抗氧化能力都是明显不同的。"

Professor Crozier said: Supplementing a healthy diet with a regular intake of a variety of fruit juices such as purple grape juice, grapefruit juice, cloudy apple juice and cranberry juice,will increase the consumer's intake of phenolic antioxidants.

Crozier教授说：有规律的食用多种果汁如紫葡萄汁，釉子汁，苹果汁和蔓越橘汁，将增加消费者酚类抗氧化剂的摄入量。

In the present study, black soybean koji were first prepared with Aspergillus awamori. The change of total phenolics , isoflavone content and antioxidant activity of black soybean and black soybean koji after heating at various temperature（40,60,80,100℃）for 30 min and storage at 4℃ and 25℃ for 120 days under different packaging conditions（desiccant + deoxidant, desiccant, deoxidant , without desiccant and deoxidant）was investigated. The antioxidant activity examined included DPPH radical-scavenging effect, Fe2+-chelating effect, trolox equivalent antioxidant capacityand reducing power.

本研究以Aspergillus awamori作为菌酛制备黑豆麴，探讨黑豆及黑豆麴经不同温度（40、60、80及100℃）加热30分钟，以及在不同包装条件（乾燥剂+脱氧剂、乾燥剂、脱氧剂及不添加任何食品保存剂）与不同温度（4℃及25℃）下储存120天过程中总酚类化合物含量、总异黄酮素含量及异黄酮素组成及其甲醇萃取物抗氧化活性之变化，抗氧化活性之检测项目包括DPPH自由基清除能力、亚铁离子鳌合力、Trolox equivalent antioxidant capacity及还原力。

Salicylic acid is a simple hydroxybenzene in plant. As a endogenesis signal molecule, the effects of SA on many physiological progress in plant have been paid more and more attention.

水杨酸(salicylic acid，SA)是植物体内产生的一种简单酚类物质，作为植物内源信号分子，在植物许多生理过程中的作用越来越受到重视。
