麝香酮

Results: Muscone, androsterone and cholesterol in both natural and man made musk were analyzed quantitatively simultaneously by GC/MS, which was highly selective to the components to be determined by selecting the characteristic fragments.

结果 ：采用GC/MS法同时测定了天然麝香及人工麝香中的麝香酮、雄甾酮及胆固醇含量，该法通过选择特征碎片定量，对待测组分有很高的专属性。方法学研究表明以上方法实用、准确。

Objective To observe the effect of muscone on the blood-brain harrier and neuropathological changes after complete cerebral ischemia/reperfusion of rats.

目的 观察麝香酮对大鼠完全性脑缺血后再灌流期间血脑屏障及神经病理改变的影响。

Objective:To estabLish a method for determination the content of Muscone in Shexintong Capsules.

目的：建立麝心通胶囊中麝香酮的含量测定方法。

Objective To study muscone and exaltone content of cosmetics by high performance liquid chromatography.

目的研究高效液相色谱法测定合成化妆品香料麝香酮及黄蜀葵酮含量。

Results: Muscone could pass through the normal rat's blood brain barrier into the brain and soon reached the highest peak and remained in higher concentration, and more slowly metabolized as compared with other organs.

用麝香的主要有效成分麝香酮，经大鼠尾静脉注射，按不同时间取其脑等内脏，制备组织样品，用气相色谱法测定其透过血脑屏障的脑内分布和其他脏器分布。

Interestingly at l2h Cinnamylaldehyde could increase HUVEC adherence to THP-1.(5) At 4h and l2h Muscone decreased PMN-HUVEC adhesion, as well as inhibited ICAM-1, VCAM-1 and CD44 expression on TNF-primed HUVEC. But it markedly increased HUVEC adherence to THP-1 at 12h.

结果提示：黄芪多糖、川芎嗪、桂皮醛和麝香酮可以抑制PMN与HUVEC粘附并抑制HUVEC表面粘附分子的表达，桂皮醛和麝香酮能明显促进THP-1与HUVEC粘附。

The titled compound as an intermediate for preparing muscone is obtained by reacting a tetradecanedioic acid as the starting material with a chlorinating agent——chlorosulfoxide,followed by reacting the resultant reaction product on halogenomethylzinc .

采用直链十四碳二元酸为起始原料，先以氯化亚砜进行酰化，所得酰氯直接与甲基锌试剂反应进行甲基化，从而制得了合成麝香酮的重要中间体2，15-十六烷二酮，产物结构经1HNMRI、R确认。

Through chemical analysis, muskrat of excretive of the cell outside body is sweet as sweet as natural excretive muskrat all contain annulus seventeen alkyl ketone, muskiness ketone and cycloalkanes kind, ester kind, mellow kind with aldehyde kind wait for composition.

经过化学分析，体外细胞分泌的麝鼠香和自然分泌的麝鼠香均含有环十七烷酮、麝香酮以及环烷类、酯类、醇类和醛类等成分。

Bisbenzimidazolium salts were used as a tetrahydrofolate coenzyme model, and thus the biomimetic synthesis of twenty-four acyclic diketones as precursors for macrocyclic ketones was successfully accomplished by using the addition-hydrolysis reaction of the bisbenzimidazolium salts with alkyl magnesium halide, wherein six diketones have not been reported in literature.

在本文中，受四氢叶酸辅酶的一碳单元转移反应的启发，作者以双苯并咪唑盐作为四氢叶酸辅酶模型，利用格利雅试剂与双苯并咪唑盐的加成-水解反应，成功合成了二十四种作为麝香酮及类似大环酮重要前体的长链二酮，同时，提供了一种麝香酮及类似大环酮的仿生合成新方法。

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.
