项目摘要

The research project focusing on dynamic and functional aspects of plant secondary metabolites covers very wide research areas. The results achieved in the project for three years have been reported as 61 reseach papers including 3 papers in press and 2 papers submitted, and 2 books, in addition to 83 oral presentations. Our reseach results are summarized as follows :(1) Establishment of new NMR techniques and application to structure elucidation of biologically active natural products, and development of in situ analytic methods of bioactive amines and calcium (11 papers).(2) Structure elucidation and quantification of anthocyanins in flowers and potatoes, and new polyphenols and terpenoids in higher plants (13 papers).(3) Plant secondary metabolites possessing alpha-glucosidase inhivitory and antioxidative activities, and their structure, structure-activity relationships and mode of action (5 papers).(4) Plant defense agents : allelopathic, insecticidal and antifeeding principles, and antimicrobial substances in the family Rosaceae (18 papers, 2 books).(5) Studies on biosynthesis, metabolism and functions of flavonoids as general defense substances in plants (6 papers).(6) Chemical studies on interactions between plant and pathogenic, symbiotic and epiphytic microorganisms (3 papers).Through such a lots of researches, we can now understand a little well about the significancy of plant ecochemicals taking many kinds of roles among living substances in the ecosystem based on autotrophic plants and heterotrophic organisms. It is our confidence that the necessity of further studies on plant ecochemicals is increasing more and more to find the way to low-input sustainable agriculture as well to find our new life style to coexist forever with other organisms on the earth.

该研究项目着重于植物二级代谢产物的动态和功能方面，涵盖了非常广泛的研究领域。据报道，该项目在该项目中取得的结果已有61篇参考论文，其中包括3篇新闻和2篇论文，以及2本书，除83篇口头介绍外。我们的参考结果总结如下：（1）建立新的NMR技术和用于阐明生物活性天然产物的应用，以及开发生物活性胺和钙的原位分析方法（11篇论文）。在花和土豆中定量花青素，以及较高植物中的新多酚和萜类化合物（13篇论文）。（3）植物二次代谢物具有α-葡萄糖苷酶吸入性和抗氧化活性，抗氧化活性，及其结构，结构 - 活动关系和作用模式（5）（4）植物防御剂：家族渣ce中的类化，杀虫剂和抗原原理以及抗菌物质（18篇论文，2本书）。（6篇论文）。（6）关于植物与致病性，共生和附生微生物之间相互作用的化学研究（3篇论文）。通过如此大量的研究，我们可以很好地了解植物生态学的重要性基于自养植物和异养生物的生态系统中生物物质之间的作用。我们的信心是，对植物生态学物质进行进一步研究的必要性正在越来越多，以找到低入可持续农业的道路，以找到我们的新生活方式，以与地球上其他生物永远共处。
