1 引言紫外光谱法已广泛用于化学药物及中草药有效成分的定性定量分析,但以不同方式用于中药材及中成药制剂鉴别方面的报道甚少。中药材化学成分复杂,其混合成分的紫外吸收光谱应是各个组分特征的叠加光
1 Introduction Ultraviolet spectroscopy has been widely used in qualitative and quantitative analysis of active ingredients of chemical drugs and Chinese herbal medicines, but very few reports on the identification of traditional Chinese medicines and proprietary Chinese medicines in different ways. The chemical composition of Chinese herbal medicines is complex, the UV absorption spectrum of the mixed ingredients should be superimposed on the characteristics of each component
