Synthesis of glucoside compounds of ferrocenyl phenols and their antianemic activity

Six glucoside compounds have been synthesized by means of phase-transfer catalytic method and deacetylation from the starting material ferrocene. Their structures have been confirmed by elementary analysis, IR,¹HNMR and MS. The antianemic activities of some compounds have also been tested. Results indicate that these glucoside compounds possess the antianemic activities and therefore, the further study is well worth making.

Studies on a series complexes of copper (II), zinc (II), cobalt (III) with Schiff base derived fromd-glucosamine and salicylaldehyde

Copper (II) zinc (II) cobalt (III) complexes with the Schiff base derived from salicylaldehyde andd-glucosamine were synthesized. These compounds abbreviated as SG, CuSG, ZnSG, CoSG were characterized by elemental analyses, IR, UV-Vis,¹H NMR and MS spectrum. ESR spectrum, magnetic susceptibility measured by Evans method for CuSG had also been done. It is suggested that the complexes in solution have pseudotetrahedral structure. It was found that SG would occur a photochemical reaction if a beach of 355 nm ultravisible light shone on its aqueous solution. The reaction was in further research.

构建及表达小麦高分子量容蛋白基因5′端调控序列缺失突变体嵌合质粒

通过定点突变，在小麦高分子量（ＨＭＷ）谷蛋白基因５′上游调控序列的ＴＡＴＡｂｏｘ与基因翻译起始密码子ＡＴＧ之间，改变三个碱基，产生新的ＢａｍＨⅠ内切酶位点．在调控序列中，选择四个合适的内切酶，对上游序列进行缺失，分离到四个大小分别为２４００、６１０、４４０和１１０ｂｐ的含有不同调控元件的ＨＭＷ谷蛋白基因启动子，与质粒ｐＢＩ１０１．１的报告基因ＧＵＳ重组，构建了四个嵌合质粒ｐＷＧ２４００、ｐＷＧ６００、ｐＷＧ４４０和ｐＷＧ１００．经基因枪、微束激光和ＰＥＧ等方法将ｐＷＧ２４００转化玉米胚乳悬浮细胞，ＧＵＳ基因获得表达．这为进一步研究ＨＭＷ谷蛋白基因的调控机理奠定了基础．

隐士与中国传统农学

隐士是中国古代社会的特殊产物，作为士，他们掌握着一定的文化知识，而作为隐士，他们又不得不自食其力，且多以农耕为生，知识与农业生产实践的结合，产生了隐士农学家和隐士农书，并在中国农学史上占有举足轻重的地位。本文探讨了隐士农学家的产生、隐士生活对农学的影响，并对隐士的农学贡献进行了评价。
