摘　　要：金属离子(M)容易接受配体,成为中心离子,二氢杨梅素(DMY)是藤茶中活性最强的天然活性物质,可作为多基配体与金属发生络合反应。本文研究了DMY-M系统的紫外光谱、荧光光谱及红外光谱,与DMY相比,DMY-M有以下特点:紫外光谱吸收峰、荧光光谱发射峰位置基本不变,但强度减弱;羰基红外吸收峰发生红移,并在500—700cm-1出现M—O吸收峰。Metals can easily receive ligand and act as the central ion.Dihydromyricetin（DMY） is the most active natural substance in teng cha（Ampelopis grossedentata） and being a polyligand,can be complex with metal ions.The UV,fluorescence and infrared spectra of DMY-M were studied.Compared with the spectra of DMY,the spectra of DMY-M system showed the following features：in UV and fluorescence spectra,the peak basically did not shift,but the UV and fluorescence intensity weakened.Red shift for infrared absorption peak of carbonyl occured,and there were absorption peak of M-O in 500—700cm-1.
