| 摘 要： | 利用紫外-可见光谱的方法，对从中药黄芩中分离得到的3种黄芩有效成分的分子结构进行了研究。通过分析黄芩有效成分在甲醇溶液中及分别加入甲醇钠(NaOMe)、醋酸钠(NaOAc)、醋酸钠/硼酸(NaOAc/H3BO3)等5种诊断试剂后的紫外-可见光谱特征，讨论了利用紫外-可见吸收光谱推断黄酮类化合物母核结构及取代基位置的方法，为天然产物有效成分的结构鉴定提供了参考依据。

| Abstract: | The molecular structures of three active components from scutdlaria baicalensis have been studied by ultraviolet-visible spectra. The index flavonoid structures and substituted positions were deduced by analyzing the UV-Vis spectra in the methanol solution of three active components and the methanol solution with 5 diagnostic reagents, NaOMe, NaOAc, NaOAc/H3BO3, AlCh, AlCh/HCl respectively, which provided strong evidences for the structural characterization of the active components from natural products. |
