Through the analysis of LC/MS and quanta chemistry study, it was concluded that there was the coexistent substance with DMY in Ampelopsis grossedentata bud dry leaf.

本研究所采用的原料显齿蛇葡萄幼嫩芽头干叶中二氢杨梅素含量高达20.27%；总黄酮含量为30.22%。

Dihydromyricetin is an important kind of flavonol. Lysozyme is a antiblastic enzymes which are widely used in the area of medicine, food service industry and chemical lines.

摘 要：二氢杨梅素是一种重要的黄酮类物质，溶菌酶是一种广泛应用于医药、食品、化工行业的抑菌酶类。

The content of total anthocyanin, total flavonoids and total phenols of arbutus juices were measured by spectrophotometry.

结果如下：对杨梅进行榨汁，并测定其花色苷、总黄酮、总酚含量。

Results β-Stigmasterol (1), quercetin (2), myricetin 3'-methyl ether (3), syringetin-3-0-α-L-arabinofuranosid (4), ardicrenin (5) and ardisiacrispin A (6) were isolated and identified.

结果 分离并鉴定出6个化合物：β-豆甾醇(1)、槲皮素(2)、3'-甲基杨梅黄酮(3)、丁香亭－3-O-α-L-阿拉伯呋喃糖苷(4)、ardicrenin(5)和ardisiacrispin A(6)。

By means of molecular mechanics and molecular dynamics methods, the binding modes and inte-ractions between newly found matrix melalloproteinases inhibitors, Pyrogallic acid and Myricetin, and MMP-7 were investigated in the present study.

采用分子力学和分子动力学方法，考察了MMPs抑制剂、焦性没食子酸和杨梅黄酮与MMP-7的具体结合方式以及相互作用的情况。

Superior messenteric artery was used to compare the changes in vascular responsing to NE or myricetin with or without 18α-glycyrrhetinic acid (18α-GA).

各组取其肠系膜上动脉制成血管环，分别测量在18α-甘草次酸（18α-GA）作用前后血管环对NE和杨梅黄酮反应性的变化。

GA antagonized SMA constriction induced by myricetin. The antagonizing effect on myricetin in shock 1, 2 and 3 hours groups was more obvious than that in the other groups. CONCLUSION :At the early stage after hemorrhagic shock, the endothelium-dependent and independent vascular contractile response show a compensatory increase.

SMA血管环对杨梅黄酮的反应主要表现为：休克0、0.5、1和2 h组明显高于正常对照组，于休克2 h达最高点；休克3 h和4 h组明显低于正常对照组，运用18α-GA阻断MEGJ后，各组血管环的收缩反应性较18α-GA作用前明显下降，其中以休克1、2和3 h组下降幅度明显大于其他组。

Thetotal amount of 13 kinds of acid methanol soluble phenolic substances in female plant leaves ofAcer negundo L.was also significantly higher than that in male plant leaves.

因为原儿茶酸、丁香酸、苯甲酸、肉桂酸、杨梅黄酮等组分的含量较高，复叶槭雌株叶片中13种酸性醇溶性酚类物质的总量普遍高于雄株(p＜0.01)。

The project's aim is to construct an industrial base whose size is 100thousand mous;to construct one production line of the deep processed goods includesQinJiantea(600t/year),instant tea (10millionbox/year) QinJiam tea Buccal Tablet (10millionbox/year),etc.to construct one refinery production line of flavonol(output is 100t/year)and one refinery production line of Dihydromyricetin (outputis 50t/year).

总投资10000万元，用三至五年时间，完成&秦简茶&产业基地建设10万亩；建成秦简茶(600吨/年)，速溶茶(1000万盒/年)，秦简茶含片(1000万盒/年)等深加工系列产品生产线及黄酮素(100吨/年)，二氢杨梅素(50吨/年)提取生产线各一条。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
