在丹参多糖的提取中,用纤维柱层析前,用氢氧化钠处理纤维素,请问氢氧化钠的浓度是多少?

(1)(8X+5Y-4M)+(6X+7Y+9N)-(11X+9Y-2M+7N)=3X+3Y-2M+2N.说明：两次计量中,地黄和丹参总共被多记了一次,故两次相加减去总量就是地黄和丹参一共的重量.
(2)1.2.根据第一式,变形得3*(X+Y)-2*(M-N)=3*0.8-2*0.6=1.2

这要一点点地查才行,你也可以采用这些植物的拉丁文名称.
先将我知道的写下来：
丹参：Dan-Shen Root
金银花：Japanese Honeysuckle
杜仲子：Eucommia Bark
天山雪莲：Herba Saussureae Involucratae

解题思路：根据丹参酮的结构简式判断其含有的官能团名称，然后根据有机物分类方法与官能团的关系判断丹参酮的类型．

分子中含有苯环，还官能团碳碳双键、碳氧双键，
A．该有机物中含有氧原子，不属于烃类，也不属于芳香烃，为芳香族化合物，故A错误；
B．该有机物分子中含有C、H、O三种元素，含有官能团碳碳双键、碳氧双键，属于烃的衍生物，故B正确；
C．丹参酮中不含酯基，不属于酯类物质，故C错误；
D．丹参酮分子中不含醛基，不属于醛类，故D错误；
故选B．

点评：
本题考点： 烃的衍生物官能团．

考点点评： 本题考查了有机物结构、烃的衍生物官能团类型，题目难度不大，注意掌握常见有机物的分类方法，明确有机物官能团与有机物分类方法之间的关系．

是用纤维素柱层析提纯吗?我知道用纤维素酶进行丹参多糖的提取的方法步骤,用DEAE-SepharoseFvast Flow纯化.

The component from different habitats salvia miltiorrhiza
The purpose) salvia miltiorrhiza (for dicotyledonous plants lamium salvia miltiorrhiza roots and Ian west sage, with blood, dispelling the stasis menstrual function, cool blood away pain syndromes except vexed, also raise blood to tranquilize the nerves role. Origin also many, the main producing area in sichuan, shandong, anhui, gansu, zhejiang etc, and collect different origin of medicinal herbs, to its composition HDP analysis, find out from the composition of different between salvia miltiorrhiza distinction, will the application of salvia miltiorrhiza has great significance. (methods) for this experiment USES the methanol extraction salvia miltiorrhiza filtration,
Will the filtrate diluted with chromatographic methanol with UPLC - Q/TOP in the literature, the total ion flow chart analysis, using Simca spectrum of different origin - P of salvia miltiorrhiza comparison to find out the distinction. (results) that under the same conditions for the total ion flow chart has certain otherness; Sinca - P in the graph, the score from a pharmacy salvia miltiorrhiza qingping medicine with from the market share is relatively far HDP. (conclusion) of different components have certain of salvia miltiorrhiza producing difference, and more significant differences between sources.

Abstract: This paper aims to investigate the characteristics and rules of adverse reaction when using Salvia miltiorrhiza and its agents. The methods used are records statistics and analysis to the adverse reaction cases during 1996 ~ 2009 in my practicing unit. The result shows that adverse reactions caused by salvia miltiorrhiza mainly occur within 30 minutes after taking medicine and mainly in the 50 ~ 59 years old age group. The main phenomena are skin allergy, anaphylactic shock, cardiovascular system response, the digestive system response etc, in which has the anaphylactic shock is highest. So the conclusion is that clinical doctors, nurses and pharmacists should pay attention to the adverse reactions caused by salvia miltiorrhiza to ensure reasonable, safe and effective in taking drugs.
