草酸

The detection sensitivity of the new method is shown higher than the old method that it can be used to the identification of Monoammonium Glycyrrhizinate in Compound Ammonium Glycyrrhetate Injection.

本方法的检测灵敏度较原方法高，可用于复方甘草酸单铵注射液中甘草酸单铵的鉴别。

Studied the extraction and purification of glycyrrhiza acid from licorice residue,obtained the better process condition through effect factors and orthotropic experiments,the yield of monoammonium glycyrrhizinate was 1.45% and content was 95%.

对超临界萃取后固形物提取纯化甘草酸的工艺进行了研究，通过影响因素试验和正交试验得出最佳工艺条件，甘草酸铵收率1.45％，纯度95％。

The present invention discloses one kind of compound preparation comprising monopotassium glycyrrhizunate 20-75 weight portions, glycine 1-800 weight portions, L-cysteine hydrochloride 10-28 weight portions, and one or two of sodium chloride 10-30 weight portions, anhydrous sodium sulfite 10-28 weight portions and disodium edetate 1-9 weight portions.

本发明公开了一种含甘草酸单钾盐的复合制剂，由下述重量配比的组分制成：甘草酸单钾盐20-75份，甘氨酸1-800份，L-盐酸半胱氨酸10-28份，和氯化钠10-30份，无水亚硫酸钠10-28份，依地酸二钠1-9份中的一种或两种以上的混合。

The comparison for advantages and application scopes of both methods were carried out. The results show that the former is quicker, but the adding amount of oxalic acid needs to be controled in the range of 1.2-1.7 times of theoretical value and the content of iron in the alloy is required to be below 0.5%. While the later is overelaborate, but it can completely separate magnesium from iron with sharp titration end point.

分析对比了两种方法的适用范围，结果表明，草酸分离稀土方法简便快速，但草酸用量需控制在理论用量的1.2~1.7倍，且合金中铁含量要求小于0.5%；氢氧化铵分离稀土方法分析流程比前者长，但可将主要干扰杂质铁分离完全，终点敏锐。

Carnosic acid, an antioxidant polyphenol derived from Sage and Rosemary, is a lipophilic antioxidant that scavenges singlet oxygen, hydroxyl radicals, and lipid peroxyl radicals, thus prevents lipid peroxidation and the disruption of biological membranes.

鼠尾草酸则是存在於鼠尾草和迷迭香中的多酚类化合物，在过去实验指出鼠尾草酸也是一种抗氧化剂。

The results showed that resin D290 had good ability of separation and purification of shikimic acid.

实验结果表明，D290树脂对莽草酸的吸附量大，脱附容易，可以应用于莽草酸的分离纯化。

The shikimic acid in Masson pine can be exploited and utilized as a new resource.

马尾松中的莽草酸可以作为新的莽草酸资源加以开发利用。

Shikimic acid and its derivatives have the pharmacological functions of antibacterial, antitumor, antithrombotic activity and anti-cerebral ischemia, etc.

结果：莽草酸主要是从中药八角茴香中提取的一种单体化合物，莽草酸及其衍生物具有抗菌抗肿瘤、抗血检形成和抗脑缺血等作用。

Shikimic acid as precursor for biosynthesis of alkaloid and other compounds,has been concerned recently as the key material for the synthesis of tamiflus that is the only one effective clinic drug against avian influenza.

莽草酸是合成生物碱等许多其它物质的前体。近年来，莽草酸作为临床上惟一有效的抗禽流感药物——达啡的原料而倍受关注。

Synthesis of poly catalyzed with stannous oxalate ;2. The thermal decomposition of stannous oxalate was investigated by differential scanning calorimetry.

以草酸和氧化亚锡为原料，用室温固相一步反应法合成了草酸亚锡，用红外光谱和热重技术对产物进行了表征。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
