The distributing profiles of different phenol derivatives in two - dimensional chromatogram were discussed 同时对不同类型的酚类化合物在二维气相色谱上的分布模式进行了讨论。
Their main adantage is that they protect against numerous diseases such as cancer or cardioascular disease 多酚类化合物的主要优点在于它们能够预防众多疾患如癌症、心血管疾病等。
Standard method for hygienic examination of phenols in air of residential areas - 4 - aminoantipyrine spectrophotometric method 居住区大气中酚类化合物卫生检验标准方法4 -氨基安替比林分光光度法
Cumene isopropyibenzene for industrial use - determination of content of phenols and cumene hydroperoxide - high performance liquid chromatographic method 工业用异丙苯中酚类化合物和过氧化氢异丙苯含量的测定高效液相色谱法
They are found in many common consumer products , primarily in fruit and egetables but also in processed products such as chocolate , tea or wine 酚类化合物存在于许多常见食物中，特别是在水果蔬菜及其加工产品如巧克力、茶叶或葡萄酒中。
The reactions were conducted under mild conditions and gave excellent yields , so they could be applied to the preparation of gibberellic acid esters for structural diverse alcohols and phenols 结果表明这两种方法具有反应条件温和、产率高的优点，可适应多种结构类型的醇和酚类化合物。
Abstract : in this paper , a imidazole - salt was synthsised and was used with a polyphenol compound to modify the dicyandiamide curing epoxy resin system 文摘:本文针对双氰胺固化环氧树脂时的固化温度高，固化产物耐湿热性差的缺点，利用自行合成的咪唑盐和多羟基酚类化合物，对双氰胺固化体系进行了改进。
Another phenolic constituent is tea , theogallin , accounts for approximately 1 percent of the dry weight of the leaf . chlorogenic acid , also a phenolic compound , is a minor constituent in tea 茶叶中另一酚类组分是3 -邻-没食子酰奎尼酸，它约占茶叶干重的1 % 。同属酚类化合物的绿原酸在茶叶中是次要成分。
Polyphenols hae much better antioxidant properties than itamins , and hae been the object of growing interest on the part of nutritionists , epidemiologists , agrifood firms and consumers oer the past decade or so 多酚类化合物比维生素有着更好的抗氧化特性，在过去的十年间，多酚类化合物已经逐渐引起了营养学家、流行病学家、农业食品公司及普通消费者的兴趣。
The trend of the ec50 and the lc50 to four kinds of organism is similar to each other . daphnia magua straus is the most sensitive orgnism among the four orgnism according to the toxicity data , and photobacteriumphosphoreum is in the next place 酚类化合物对4种受试生物的ec _ ( 50 )值和lc _ ( 50 )值的趋势一致，其小，大型蚤对受试物的毒性反应最为敏感，其次是发光菌。
