S extract had an inhibition effect against Sphaerotheca fuligenea,The inhibition rate was 100% when extract concentration was 20mg/mL and the inhibition rate got to 67.66% even at the concentration of 2.5mg/mL. The extract of E. humifusa had different preventive effects against four strains of S. fuliginea from four districts in Shanghai. The preventive effects on the Qibao and Baoshan were better than those of Nanhui and Qingpu. The microorganism inhibition experiment by filter papers indicated that the extract of E. humifusa had higher inhibition effect against bacteria than on pathogenic fungus. Diameters of the zone of inhibition of salmonellas, Echerichia coli and Staphylococcus aureus were 15.77mm, 12.27mm and 10.53mm respectively. The extract of E. humifusa had a certain effect against Colletotrichum lagenarium, Botrytis cinerea, Rhizoctomia solan and Pyricularia oryza but no effect against Helminthosporium maydis and Gibberella zea. The 4 cation exchange resins and ethanol deposition were used to isolate the active fractions from supernate after alkali deposition.

提取液对黄瓜白粉病菌体外分生孢子萌发抑制实验表明地锦提取液对黄瓜白粉病菌分生孢子的萌发有很好的抑制作用，抑制率随着地锦提取液浓度的增大而增高，当浓度为20mg/mL时，抑制率达到100%，即使在浓度为2.5mg/mL时，抑制率也达到了67.66%；室内盆栽苗期预防性实验表明了地锦提取液对上海4个不同地区的黄瓜白粉病菌均具有不同程度的抑制效果，对七宝和宝山地区的菌株抑制效果优于南汇和青浦地区的菌株；用滤纸片法测定了地锦提取液的抑菌谱，实验结果表明地锦提取液对供试的4种植物病原真菌：黄瓜炭疽病菌、黄瓜灰霉病菌、水稻纹枯病菌和水稻稻瘟病菌均具有一定的抑制效果，而对玉米小斑病菌和小麦赤霉病菌没有抑制效果，对供试的3种人类致病细菌沙门氏菌、大肠杆菌和金黄色葡萄球菌均具有很好抑菌效果，抑菌圈直径分别为：15.77mm， 12.27mm和10.53mm。

Objective: To investigatre appropriate macroporous resins and the optimal technological parameters of the purification process of tartary buckwheat total flavonoids.

中文摘要：目的：筛选分离苦荞总黄酮精制的最佳树脂型号及最佳工艺。

In this method,β-cyclodextrin epichlorohydrin polymer of 60-80 mesh, which has less background absorbance in ultraviolet and visible region compared to other ion-exchanger resins, was used to support direct adsorption of tartrazine from aqueous solutions to form a solid complex (tartrazine-β-CDP complex). The effects of pH, temperature, time and ionic strength on the β-CDP including tartrazine were determined.

在这个方法中，所利用的β-环糊精聚合物（60-80目）和离子交换树脂相比，在紫外和可见光区吸收很小，其作为固体相的支持体，并用於从样品溶液中分离收集柠檬黄，然后在435nm波长下直接用於测定。

The present research work focuses on two aspects. On one hand, the most successful alkaloid-derived ligands have been attached to a soluble or insoluble support covalently, but additional OsO〓 is necessary to maintain the consistent catalytic activity during the reuse of supported chiral ligand in the next AD reaction. On the other hand, immobilization of osmium tetroxide based on microencapsulation, ion-exchange techniques, and osmylation of resins has made it possible to recover and reuse of the osmium, but failed to recover the chiral ligand at the same time.

目前的研究主要集中在两个方面：一方面，将手性配体共价键合到不溶或可溶性载体上制成负载手性配体，但在重复使用负载配体时必须补充OsO〓，才能保证催化活性不降低；另一方面，将OsO〓包裹在高聚物微囊内，或运用离子交换技术或共价键合的方法将OsO〓固载在树脂、硅胶或层状双金属氢氧化物材料上，但手性配体却不能同时回收。
