The preparation process of equisetum pratense total alkaloid includes the following steps: coarse pulverizing equisetum pratense to obtain rough powder, methyl alcohol percolation to obtain percolate, recovering methyl alcohol, concentrating, degreasing by means of petroleum ether, alkalifying concentrate, CHCl3 extracting, soda lye washing, neutral water washing, recovering CHCl3 to obtain rough alkaloid, adsorption by using silica gel column, eluting, recovering solvent so as to obtain refined EPR.

该发明是通过两个步骤来实现的：第一步，提取草问荆总碱，流程：草问荆粗粉――渗漉液――浓缩液(析胶、石油醚脱脂、氨水碱化)――碱化浓缩液(CHCl3萃取)――CHCl3层――CHCl3液(回收CHCl3)――粗生物碱――吸附硅胶柱――精致EPR。第二步，选择实验试剂、仪器、用小鼠作为实验对象，进行中枢神经系统实验，研究作用及作用机制。

Will withdraw, condense two output evaporations to get into the reflux congealed machine a hot and congealed liquid in the meantime, drop to withdraw in the bottle, is a new melting agent to add a medicine material noodles up, renew continuously solid-liquid two connect a people's layer, make the new melting agent is from the top to descend to pass a medicine material layer, have the dynamic state 渗漉 function, the dissolubility material which fuses a medicine material arrives to withdraw a bottle of bottom, and then gets into inspissation machine to carry on inspissation.

同时将提取、浓缩产生的二次蒸发进入回流冷凝器成热冷凝液，回落到提取罐中，作为新溶剂加到药材面上，不断更新固——液两相接口层，使新溶剂从上至下通过药材层，起了动态渗漉作用，溶解药材的可溶性物质到达提取罐底部，又进入浓缩器进行浓缩。

Decoction was percolated with 9-fold volume of 70% ethanol at the velocity of 3 mL/min and the optimal isolation technology was that the pH of curcumin sample solution was regulated to 7 by 0.01 mol/L HCl and 0.01 mol/L NaOH solution and 80% ethanol was used for elution of the velocity of 4 mL/min.

结果：提取姜黄素用9倍体积的70%乙醇，以3 mL/min的速度渗漉为最佳提取工艺；利用D101大孔树脂纯化姜黄素工序中调节上样料液pH为7，用80%乙醇以4 mL/min的速率洗脱为最佳分离工艺。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
