查询词典 host plant

Based on the changes in the spectrum characters of guest molecules producedthrough inclusion complex formation with cyclodextrins, we have carried out two aspects of investigation:First, the mechanisms for the host-guest recognition reactions have been studied, such as the interactions between 3-CD and curcumin, the main constituent of the rhizomes of the plant Curcuma longa, the recognition of p-CD towards rubidate, the effective component of the Chinese traditional medicine madder, and the reactions of p-CD towards the antileprotic drug dapsone and the antiinflammatory drug nabumetone: The formation of supramolecular complex between P-CD and guest molecule has been discussed and verified in virtue of multitudinous means such asultraviolet-visible absorption, fluorescence emission, infrared spectrogram and so on. The influence of addition of linear alcohols on the supramolecular system has been studied and the reason why the noncovalent interactions in the three-component system could result in a decrease in the apparent association constant of the inclusion complex has been revealed.

本论文基于环糊精对被包结客体光谱性质的改变，开展了两大方面的研究：β-环糊精对姜黄属植物根茎主要成分—姜黄素、中药茜草有效成分—茜草双酯、抗麻风药物氨苯砜及抗炎药物萘丁美酮的主-客体识别反应机制研究：借助超分子包合物的紫外吸收光谱、荧光光谱或红外吸收光谱等手段，通过多种方法探讨并验证了超分子包合物的形成；研究了直链醇的加入对超分子体系的影响，揭示了三元体系中非共价相互作用导致超分子包合物表观结合常数降低的原因：对超分子包结反应进行了热动力学研究，探讨了各热动力学参数的变化趋势并从熵焓互补的角度考察了超分子包结过程；通过荧光猝灭实验进一步揭示了水相中β-环糊精增敏客体荧光的本质原因，从而为超分子化学提供新的理论和研究方法。
