The reason may be that complex formed by rhodium and halide was difficult to produce the catalytic active species. Therefore halide ion was the poison for the rhodium catalyst in hydroformylation of olefins in ionic liquid. The effect of double long chain cationic surfactant (DCMAB, dicetyl dimethylammonium bromide) on selective hydrogenation of cinnmaldehyde catalyzed with RuCl3·x H2O/TPPTS was studied.

进一步的研究表明在使用有良好反应活性的两种催化剂HRh3 、Rh_2进行催化反应时，向体系中加入含有卤离子的化合物时将使反应活性大大降低，而且随着卤化物加入量的增加，催化剂的活性迅速下降，这是卤离子可能和金属铑作用使它难于生成催化活性物种，进一步证明卤素离子是引起催化剂活性下降的极其重要的因素。

Coli and S.aureus , the experiment showed that recombined gene peptide has the antibacterialactivities.Conclusion The recombined gene antibacterial peptide was expressed successfully in the fusional pTYB vetor and the fusion gene peptide CA(1 ~8-MA(l ~12),CAM has the antibacterial activities to E. coli and S.aurens. While how to frame a more efficient expression system should be studied further , and its other biological activities are still to be tested.

The testing method of ACE inhibitory activities was studied, and the antihypertensive peptides were derived from mytilus coruscus, then the ACE inhibitory activities were studied on different conditions; the antihypertensive effects were tested by SHR-feeding method.

探讨了ACE抑制活性的检测方法，并以贻贝原料制取降血压肽，研究了不同酶解条件对其ACE抑制活性的影响，然后利用SHR饲喂试验检测其降血压活性结果表明，降血压肽有较好的ACE抑制活性：其ACE抑制率可达88.08%。

Coli. The antimicrobial activity of the recombinant fusion protein was evaluated in vitro, which exhibited high antimicrobial activity against Bacillus subtilis, Staphylococcus aureus, and Pasteurella multocida, but low antimicrobial activity against Escherichia coil, and no antimicrobial activity against Salmonell choleraesuis.

对该重组蛋白进行纯化与体外抗菌活性的测定。结果表明，重组鸡AvBD6融合蛋白对多杀性巴氏杆菌、金黄色葡萄球菌、枯草芽胞杆菌有较高抗菌活性，对大肠杆菌的抗菌活性较弱，对猪霍乱沙门氏菌无抗菌活性。

The current antifungal agents used in clinics usually have severe side-effects, it is necessary to seek for new antifungal agents with known or new mechanisms. China has abundant resources in traditional Chinese medicine, therefore exploition of new antifungal agents therefrom is a feasible way.We have screened antifungal activities of 14 ethanolic extracts from traditional Chinese medicines and 21 natural products by using Saccharomyces cerevisiae GL7 and Prototheca wickerhamii as the model microoranganisms. Among the TCMs tested, Cortex Phellodendri, Flos Caryophylli, Fructus Mume, Rhizoma Coptidis and Radix Sophorae tonkinensis showed high antifungal activity. This study layed certain foundation for the development of new antifungal agents.

为了开发中药资源，从传统中药中寻找有抗真菌活性的天然药物并阐明其作用机理以利于临床应用，论文对14种生药乙醇提取物及21种生药化学成分利用啤酒酵母突变型GL7（Saccharomyces cerevisiae GL7）和威克海姆原藻作为模式菌种进行了抗真菌活性筛选，其中黄柏、丁香、乌梅、黄连和山豆根等有很好的抑菌活性，为进一步研究开发成新的抗真菌药奠定了基础。

The change of agglutinating activity in different temperature and pH indicated that PML had no hemagglutinating activity at 80℃. The effect of chemical modification of amino acid residues upon hemagglutination was investigated. There was a definite decrease of fluorescence intensity which corresponds to the oxidation of tryptophan.

研究了不同温度、pH和变性剂对PML凝血活性的影响和荧光光谱的变化，当温度达80℃时，活性完全丧失；pH为4—9对活性影响不大，pH低于2和pH高于12时，大黑花芸豆凝集素的凝血活性大部分丧失；高温和强碱对荧光光谱有较大影响，表明PML对高温，强碱的耐受性不强。

We used the derivatives to do the MTT assay test and to discuss the SAR, the result teld us the isoprenyl group and the 3,4-olefinic bond of osthol is essential for its activity,and the isoprenyl group at position 8 had the better cytotoxicity. When osthol and demethylsuberosin reacted with ferulic acid to form the derivatives of (26) and (35) have the better effect of anti-cancer and IC50 value than osthol.

所以我们选择蛇床子素进行结构上的修饰并与姜黄素的部分结构形成的化合物ferulic acid结合合成出一系列的衍生物，进行抗癌细胞毒杀活性测试来探讨其结构与活性的关系，发现osthol上的isoprenyl group对於抗癌活性有重要的影响，且isoprenyl group位於C8的位置对於抗癌活性有较好的表现。
