The major bioactive components in a Chinese herb named Polygonum perfoliatum L. including ferulic acid, vanillic acid, quercetin, caffeic acid and protocatechuic acid were simultaneously determined by capillary electrophoresis with electrochemical detection in this paper.

采用毛细管电泳-电化学检测法同时分离测定了中药杠板归中的阿魏酸、香草酸、槲皮素、咖啡酸、原儿茶酸等主要生物活性成分的含量。

One valley lied between two peaks(flower beginning period and fruit maturating period).When meeting blood serum,the electron on the ring B-C and A-C of quercetin molecule would move and make -OHs of Ring B and A ionizated and one anion with double negative charge would present.

遇到血清时，槲皮素分子结构中的B环和C环、A环和C环形成的两套共轭体系中的电子，发生转移并使酚羟基解离，形成带双负电荷的阴离子，此阴离子将与人血白蛋白结构中结合位点上的氨基酸残基以离子键的形式结合。

Objective: To study the inhibitory effect of quercetin on transplantation tumor of breast carcinoma cell line MCF-7 in nude mice and its effect on the cell cycle.

目的：研究槲皮素对人乳腺癌细胞株MCF-7裸鼠移植瘤的抑制作用并探讨其对细胞周期的影响。

Middle-aged volunteers who ate a combination of bilberries, lingonberries, black currants, and chokeberries for eight weeks showed a significant increase in blood levels of polyphenols, with compounds like quercetin increasing by up to 80 per cent, according to findings published in the Journal of Agricultural and Food Chemistry .

根据农业和食品化学杂志发表的调查结果，中年志愿者谁吃了越桔，越橘，黑加仑子和 chokeberries 的组合食谱，如高达百分之八十提高槲皮素的化合物达8个星期，结果显示血液中的多酚水平显着增加。

Our experiments confirmed that two known inhibitors DRB and A3 Inhibited the activity of purified recombinant human CK2 holoenzyme, and that quercetin, its derivatives and some tyrphostins exerted stronger inhibitory effect on CK2 than DRB and A3. These results provided important experimental basis and a simple screening method for the development of more effective inhibitors of CK2 and their clinical application in the future.

本结果实验证实纯化的重组人CK2全酶可受到已知抑制剂DRB和A3的抑制，但槲皮素及其衍生物和某些Tyrphostins抑制CK2的作用较DRB和A3更强，这对于开发更有效的CK2抑制剂，为今后应用于临床提供了重要的实验依据和一种较为简便的筛选方法。
