查询词典 phenolic

The results showed that the addition of alcoholate increased the elution recovery of phenolic acids on resins in supercritical CO2. The infrared spectroscopy was used to study the interaction between solute and solvent molecules in supercritical fluid. The hydrogen bond between alcoholate entrainer and phenolic acid was the main factor to increase the ability of supercritical elution. The results appeared that salvianolic acids could be extracted by supercritical carbon dioxide with ethanol as entrainer.

结果表明：醇类夹带剂的加入能大大提高树脂上酚酸类化合物的超临界洗脱率；通过红外光谱技术研究了超临界流体中分子间的相互作用与超临界洗脱过程的关系，认为醇类夹带剂与酚酸类化合物的氢键作用是提高酚酸类化合物洗脱率的主要因素；以乙醇为夹带剂的超临界CO2洗脱可应用于丹参酚酸的提取。

Amount of auxochrome phenolic hydroxyl(0.29 unit/C9)in lignin from H_2O_2 bleaching chemi-mechanical pulp is slightly higher than one of material(0.28 unit/C9), so amount of auxochrome phenolic hydroxyl can not be effectively decreased by alkaline peroxide bleaching process.

麦草化学机械浆纸浆经过碱性H_2O_2漂白，木质素中酚羟基含量(0.29个/C9)略高于原料中的酚羟基含量(0.28个/C9)，说明H_2O_2漂白不能有效地减少木质素中酚羟基这类助色基团的数量。

In order to explore the mechanism of the resistance to cucumber damping-off induced by plant growth-promoting rhizobacteria CH1, the physiological and biochemical method was employed to study the changes in activities of Phenylalanine ammonia-lyase, Polyphenol oxidase and contents of ferulic acid, chlorogenic acid, lignin, phenolic compound and flavonoid of phenolic metabolism in cucumber roots pretreated with plant growth-promoting rhizobacteria CH1 and infected by Pythium aphanidermatum.

为研究植物生长促生细菌CH1诱导黄瓜对猝倒病的抗性的作用机制，采用生理生化的方法，测定了黄瓜根部酚类物质代谢中苯丙氨酸解氨酶、多酚氧化酶活性动态及阿魏酸、绿原酸、木质素、总酚、类黄酮含量变化。

Total phenolic content and reducing power were determined using the Folin-Ciocalteu and the potassium ferricyanide reduction methods, respectively. Statistical analysis indicated a close association between the antioxidant potency and total phenolic content, and between the antioxidant potency and reducing power as well.

酚的含量和还原能力分别用福林酚试剂和铁氰化钾还原反应来测定，统计分析显示两种蚂蚁窝的抗氧化能力和其酚含量、还原能力都存在着正相关。

为了对预浸布进行快速检测，采用近红外漫反射的方法对高硅氧/酚醛预浸布，碳/酚醛预浸布中的树脂含量、可溶树脂含量和挥发份含量进行在线监测，三项指标同时显示。

Amount of total phenolic compounds, total flavones and DPPH scavenging activity for different kinds of vinegars were compared. The results indicate that (1) DPPH scavenging activity of different kinds of vinegars has a positive correlation with amount of total phenolic compounds, total flavones, the correlation coefficients were 0.9523 and 0.8691, respectively,(2) the higher content of phenolic compounds and flavones in Zhenjiang aromatic vinegar respond for its higher scavenging activity.

对不同品种食醋总酚含量、总黄酮含量、DPPH自由基清除活性的比较分析表明：(1)不同品种食醋自由基清除活性与醋中的总酚含量、总黄酮含量存在正相关性，相关系数分别为0.9523、0.8691；(2)镇江香醋中由于总酚含量、总黄酮含量较高因而自由基清除作用较强。
