大孔

AB??8 macroporous resin was selected,and eluant was 70％ of ethanol.Conclusion The method is effective for large??

8型大孔吸附树脂，以体积分数为70%的乙醇为洗脱溶剂，4倍树脂体积。

The optimum conditions are as follows:with 70% ethanol as eluant, working solution pH 6, and series selecting AB-8 resin column for purification. Then, reasonable yield and high product purity can be obtained.

实验结果表明，洗脱剂乙醇的体积分数为70%、上样液pH值为6时，采用AB-8大孔吸附树脂串联柱对山楂总三萜酸进行纯化效果最优，产品的纯度较高。

The eluents were water, 10%, 20 %, 30 % and 50 % ethanol respectively and they flowed through the macroporous resin one by one with five times of the column volume. The obtained eluent of 50 % ethanol was evaporated and the content of total flavonoids was 76 % measured by HPLC.

结果 选择AB-8大孔树脂；最佳纯化工艺为上样液总黄酮质量浓度 60 mg·L-1，pH 5.0，温度 25 ℃；最佳洗脱方式是用5倍柱体积的水及体积分数分别为10 %、20 %、30 %的乙醇依次洗脱，弃去洗脱液后再用5倍柱体积的体积分数为50 %的乙醇洗脱；HPLC法测定总黄酮的含量为76 %。

By comparison of eight micro adsorption, A resin with high adsorption rate and eluent rate was used to adsorb chlorogenic acid from extraction solution. The adsorption parameters are: the content of chlorogenic acid is 0.204 mg per mL adsorption solution, the acidity of adsorption solution is 4, the adsorption velocity of flow is 3 mL per min, the eluent is 30% ethanol, the eluting speed is 1.5 mL per min and the eluents volume is 4 times of resin volume. In the optimal adsorption condition, the final yield of CHA is 5.06%. the content of chlorogenic acid is 78.26% in dry productin.

通过对比8种大孔吸附树脂对绿原酸的吸附效果，选用对绿原酸吸附解吸性能均较好的树脂对绿原酸吸附，吸附参数如下：吸附液绿原酸的浓度为0.204mg／mL、吸附液pH值为4、流速为3mL／min，解吸参数如下：解吸剂为30％乙醇、解吸剂流速为1.5mL／min、解吸剂使用量为4倍树脂体积，在此条件下，绿原酸得率为5.06％，产物中绿原酸含量为78.26％。

The coarse flavone is extracted from luohanguo leaves by boiling water, collected by resin adsorption, elutriated by 75% ethanol. The refined flavone is obtained by absolute alcohol purification.

罗汉果叶通过蒸馏水煮沸，经大孔吸附树脂柱吸附，75%的乙醇洗脱，旋干，得罗汉果叶子粗黄酮，再用无水酒精精制，得精制黄酮。

Owing to the disadvantages of the traditional process of austenitic stainless steel neck flange with a large hole,a new upsetting-extruding process with tubular billet was presented.

针对应用广泛的奥氏体不锈钢中间带大孔的高颈法兰类零件传统锻造工艺的不足，提出了一种利用管坯直接镦挤法兰的新工艺；用DEFORM-3D软件模拟了奥氏体不锈钢(0Cr18Ni9)法兰锻件的管坯镦挤成形过程。

Suitable macroporous adsorption resin (MAR DM-21) was chosen to separate SDG from extract solvent system (KOH-ethanol-water) of flaxseed cake.

然后用大孔吸附树脂与TLC相结合的方法，探讨了亚麻籽中SDG的分离纯化，并根据HPLC分析结果确定了最佳的分离纯化工艺条件。
