杨梅酮

The oxidation mechanism of synephrine was also investigated;(2) The electrochemical behavior of twelve flavonoids (quercetin, morin, fisetin, luteolin, isorhamnetin, myricetin, hyperoside, quercitrin, puerarin, farrerol, naringenin and hesperidin) was investigated. The method for the determination of flavonoids was developed by using different pulse voltammetry, and the detection limit was in the range of 10-7~10-9 mol/L. This method has been successfully employed to determine the total amount of flavonoids in pericarpium citri reticulatae and quercetin in the spiked human blood plasma samples.

2研究了槲皮素、桑色素、漆黄素、木犀草素、异鼠李素、杨梅素、金丝桃甙、槲皮甙、葛根素、杜鹃素、柚皮甙元和橙皮甙等12种黄酮类化合物在玻碳电极上的电化学氧化行为，建立了测定黄酮类化合物的微分脉冲伏安法，检测限可达10~(-7)～10~(-9) mol/L，并用DPV法测定了陈皮中总黄酮含量和模拟血清中的槲皮素，结果较为满意。

Result:The redox peak current was proportional to the myricetin concentration.

结果：氧化还原峰电流与杨梅酮的浓度呈线性关系。

The concentration of myricetin on MWNT/G was determined by cyclic voltammetry.

采用循环伏安法对杨梅酮的浓度进行测定。

MWNT/GC showed the better catalytic effect on myricetin and the high sensitivity to the determination.

多壁碳纳米管对杨梅酮有良好的催化活性，MWNTs/GC对于测定杨梅酮呈现良好的响应特性和较高的测定灵敏度，该传感器应用于杨梅酮的分析。

Objective:A glass carbon electrode modified with multi-wall carbon nanotube was prepared,and the electrochemical behavior of myricetin on MWNT/GC was investigated.

目的：制备了多壁碳纳米管修饰玻碳电极，并研究了杨梅酮在MWNTs/GC上的电化学性质。

Myricetin group was further divided into 7 subgroups: normal control group, 0, 0.5, 1, 2, 3 and 4 hours after hemorrhagic shock groups. Superior messenteric artery was used to compare the changes in vascular responsing to NE or myricetin with or without 18α-glycyrrhetinic acid (18α-GA).

56只SD大鼠按随机数字表法分为去甲肾上腺素组和杨梅黄酮组；NE组分为正常对照以及休克0、0.5、1和2 h 5个亚组；杨梅黄酮组分为正常对照以及休克0、0.5、1、2、3和4 h 7个亚组。

The calculated results show that the binding affinity between Myricetin and MMP-7 is higher than that between Pyrogallic acid and MMP-7 when they bind to MMP-7, thus Myricetin is more potent on MMP-7 than Pyrogallic acid. This is in agreement with the inhibitory activity order from experiments.

研究结果表明，在与MMP-7结合时，杨梅黄酮比焦性没食子酸具有更高的亲合性，因此杨梅黄酮对MMP-7有更好的效能，这与实验测得的活性顺序相符。

For the study, the researchers asked participants about their diet and estimated consumption of three flaonols: quercetin, which is most abundant in onions and apples; kaempferol, found in spinach and some cabbages; and myricetin, found mostly in red onions and berries. Oer the next eight years, 529 deeloped pancreatic cancer.

研究人员询问参与者有关他们的饮食，并估算吃三种黄酮醇的量：五羟黄酮，在葱和苹果中含量最多；山奈醇，存在菠菜和一些甘蓝菜中；杨梅黄酮，主要存在于红洋葱和莓果中，在之后八年内有529人罹患胰脏癌。

Green tea contains a number of flavonols with the basic structure Specific flavonols found in tea include myricetin (hydroxyls at carbon 3', 4', and 5'), quercetin (hydroxyls at positions 3' and 4'), and kaempferol (hydroxyl at position 4'), and their glycosides.

绿茶含有一些黄酮醇，其基本化学结构为：茶中特有的黄酮醇有杨梅黄酮(3'、4'、5'碳位上羟基化)、豕草花粉苷(3'和4'碳位上羟基化)，莰非醇(4'碳位上羟基化)，以及它们的糖苷物。

In order to explore molecular mechanism and inhibitory effects of flavones and flavonols on human esophageal carcinoma cells, the inhibition of proliferation and the induction of G2/M cell cycle arrest in KYSE-510 cells and OE33 cells treated with three flavones and three flavonols (quercetin, kaempferol, myricetin) were analyzed by MTT array and flow cytometry.

为了探索它们对人食管癌细胞的抑制作用和分子机制，采用MTT法和流式细胞术，鉴定了3种黄酮(木犀草素、白杨素、芹菜素)和3种黄酮醇(槲皮素、山奈酚、杨梅素)对2株人食管癌细胞(鳞癌KYSE-510和腺癌OE33)的增殖抑制作用和G2/M周期停滞的诱导作用。
