These dendritic NOBIN derived Schiff base ligands have been applied to titanium catalyzed hetero-Diels-Alder reaction of Danishefshy's diene and aldehydes, affording the corresponding 2-substituted 2, 3-dihydro-4H-pyran-4-one in quantitative yields and excellent enantioselectivities (up to 97. 2%ee). Comparing the reactivities and enantioselectivities of reaction catalyzed by the titanium complexes of these Schiff base ligands, it was found that a series of ligands L〓 were superior to the other three series of ligands L〓, L〓 and L〓, a significant positive NLE and a dendrimer effect existed in the L〓 dendritic catalyst system. The disposition of the dendritic wedges and the dendron size in the ligands were observed to have a significant impact on the enantioselectivity of the reaction.

The modulator could make different effect on fermentation, kerosene and triton-XlOO has little effect on fermentation, but span-20 and J3 -ionone could enhance the productivity of J3 -carotene, significantly. The content of 3 -carotene in the medium reach 2~3 times of the control experiments by adding Ig/L span-20.The effect of the mycelial morphology on producing 3 -carotene of Blakeslea tripora was also investigated.

在研究前体物和促进剂对p一胡萝卜素生产影响时发现：复合前体物添加可以提高产率到2.4倍；研究了不同小分子效应物对三抱布拉氏霉菌合成p一胡萝卜素的影响，结果表明：煤油、trinton一X 100对菌体中p一胡萝卜素含量影响较小，sPan一20可以提高卜胡萝卜素的产量，其中添加sPan一20可使p一胡萝卜素产量提高到2一3倍。

Using papain to hydrolyze the legumin and vicilin respectively showed that it could obtain higher DH from legumin than from vicilin, and the emulsifying activity of legumin hydrolysates was also increased more than vicilin hydrolysates. It was easier to hydrolyze the β-sheet fractions than α-helical fractions of broad bean legumin by papain, but to vicilin the β-sheet fractions was difficult to be hydrolyzed.

发现Papain对11S的水解程度大于7S，11S水解物的乳化活性也高于7S水解物；对水解物的圆二色性分析表明：蚕豆11S球蛋白的β-折叠结构易于被木瓜蛋白酶作用，而7S球蛋白的α-螺旋结构易于被木瓜蛋白酶作用；蛋白质分子中的α-螺旋结构对乳状液的形成和稳定起着重要作用。

The biological activities of the metal complexes of derivatives of benzaldehyde nitrogen mustard were investigated against 〓,〓 and SMMC-7721 cell lines. The interesting results were found. When the non-activity ligand combines with cobalt and nickel , the complexes have good antitumor activity, while active ligand binds to the metal, the complex has no activity, indicating there are synergic effect and counteraction between the metals and the ligands.

对所获得苯甲醛氮芥衍生物的金属配合物进行研究，观察它们对SMMC-7721、〓细胞株的作用，发现某些有趣的实验结果，无活性的配体，当与钴，镍形成配合物后，具有很好的抗肿瘤活性，而有活性的配体形成配合物后无活性，揭示在它们存在有协同作用及拮抗作用。

The applicability of chicken microsatellite primers to peafowl population was analyzed in the present paper, and the results showed 14 of 29 pairs of microsatellite primers from chicken could amplify peafowl DNA and produce specific allele patterns. A mean of 1.71 alleles was found for each locus. Seven pairs were highly polymorphic, and MCW0080 and MCW0098 were ideal markers for peafowl.
