DHCC Constance in the chemistry belongs to the onlighted Cyclopentanoperhydrophenanthrene when it reacted together with the acid Constance it could transform into the fluorescence phenol.we did the flouric determination for the DHCC, in which treated by the ethanol-sulfuric acid or acetic anhydride-methylene chloride-sulfuric acid, acquired standard curve in the 0-40μg/ml presented the liner relet...

DHCC类物质在化学上属于不发光的环戎烷多氢菲类，但与酸性物质一起反应时，可转化为产生荧光的酚类。用乙醇硫—酸或乙酸酐—二氯甲烷—硫酸处理后的DHCC进行荧光检测，获得标准曲线0—40μg/ml范围内呈线性关系，检出的最高灵敏度可达300ng/ml。该方法可用于分离后的DHCC及单一种DHCC代谢物的定性及定量分析。

In order to minimize the pollution of the environment with waste acids and/or waste acidic salt solution, following measures were taken:(1) Instead of using excess sulfuric acid, sulfonation reaction was carried out in the presence of excess toluene and the water produced during the sulphonation was removed by azeotropic distillation.

在CLT酸生产中，为了使废酸和酸性废盐水对环境的污染减少到最低程度，采取了如下的措施：(1)与使用过量硫酸相反，磺化反应是在过量甲苯的存在下进行，同时用共沸蒸馏方法移出了磺化过程中产生的水。

In the experimental study section, the rats were divided into four groups, including the normal control, the model, the Piracetam, the QPC, and copied to AD model. After the treatment, we observed the effects on the AD rats' ability of leaning and memorizing, detecting the TChE activity in whole blood and the expression levels of the related biochemical indicators of As includeing GFAP、NGF and BDNF of the AD rats' brain hippocampus, then compared the QPC with other groups to reveal the mechanism of action of the QPC treating AD to bright.
