The method of solvent together with macroporous resin extracting and separating crocin and geniposide was investigated firstly in China.

国内首次研究了溶剂浸提与大孔树脂相结合的方法对藏花素、栀子甙的提取和分离的影响，结果表明：Ⅰ。

By use of AB-8 macroporous resin and with 10％ gardenia yellow as adsorptive solution, selecting proper adsorptive and desorptive conditions, crocin and geniposide can be separated effectively, the purified gardenia yellow whose colority increases from 10 to 320 and OD ratio decreases from 2. 31 to less than 0.4 answers for the standard of gardenia yellow of high quality.

采用AB—8大孔树脂，以10％的栀子黄溶液上柱，选择合适的吸附、解吸条件，栀子黄的色价可从10提高至320，OD值比率也从2.31降至0.4以下，藏花素和栀子甙均达到了有效地分离。

Curcas seeds and physicochemical characteristics and fatty acid composition of the seed oils, among the 6 sources.

而后采用脱脂后水浴醇提的方式大量提取，结合大孔吸附树脂和硅胶柱层析

The eliminating protein rate and loss condition of polysaccharide were compared. The effectof negative ion macroporous resin was suitable. The condition of this method was gentle, easy torealize industrication, and was of decolour effect. The eliminating protein rate was79.26％,polysaccharides obtained rate was 86.3％.

从蛋白脱除率及多糖损失情况进行了比较，用弱碱性阴离子大孔树脂脱蛋白效果理想，该法条件温和、有脱色效果、易工业化生产，蛋白脱除率达79.26％，多糖回收率达86.3％。

The average recover rate is 95.4% and RSD is 3.5%. The average content of sciadopitysin is0.147%(RSD is 2.86%). 5.The technology to rich the total flavonoids in branches and leaves of Taxus yunnanensis. Methods:(1) To extract the sample by sonication;(2) Study the technology of extract and defat with L9 (3~4) orthogonal test;(3)Study the process of purification by macroporous resin: containing resin type, liquor concentration, the category and quantity of eluant.

云南红豆杉中总黄酮富集工艺的研究方法：(1)确立用超声法初提药粉；(2)用L9(3~4)正交试验考察脱脂和醇提的工艺参数；(3)用大孔树脂研究总黄酮的富集工艺：考查树脂类型、上样液浓度、洗脱曲线等。

External surface,activity and mechanical strength of the catalyst were enhanced by increasing proportion of large pores and adopting the shape of dentiform sphere.

通过对载体的改性，提高了大孔所占比例，将催化剂外形改为齿球形，增大了催化剂的外表面积，提高了催化剂的活性和机械强度。

Method］ The effect of both the different amounts of macroporous resins,diatomaceous earth and activated carbon,and the different pH values of buffer on immobilization was tested.

方法］ 以大孔树脂、硅藻土和活性炭的不同加入量作为因素，同时以缓冲溶液的不同pH值作为另外一个因素来考察对固定效果的影响。

Results The D101 macroporous resin was shown to be the best resin for the separation and purification of the total saponin from the ＂Wu-He＂ dipsacus root.

D101型大孔树脂在所确定的工艺条件下能较好地分离纯化五鹤续断总皂苷，其固形物中总皂苷的含量＞50%，总皂苷的回收率＞91%。

Based on the study of the adsorption mechnism between the macroporous weak base anion-exchange resins and the aromatic sulfonic acid, a pretreatment method for the wastewater from 4, 4'-diaminostilibene-2, 2'-disulfonic acid manufacturing process, a refractory dye intermediate wastewater, was developed.

在对芳香磺酸化合物吸附机理研究的基础上，开发了大孔弱碱性阴离子交换树脂吸附法处理4，4'-二氨基二苯乙烯-2，2'-二磺酸氧化工序生产废水的新技术，并得到了工业化应用。
