１引 言薄层色谱（ＴＬＣ）已广泛用于中药成分的分离与分析，但在薄层原位无法获得分离后各化合物的分子结构信息；表面增强拉曼光谱（ＳＥＲＳ）可高灵敏度获得单一组分的分子振动光谱，将以上技术联用，可在混合物微量分离的原位获得化合物的分子结构信息，本文用ＴＬＣ－?
1 Introduction Thin layer chromatography (TLC) has been widely used for the separation and analysis of traditional Chinese medicine components. However, molecular structure information of each compound can not be obtained in situ in thin layers. Surface enhanced Raman spectroscopy (SERS) Molecular vibrational spectroscopy, the above technology combined with the mixture can be obtained in situ micro-separation of compounds molecular structure information, the paper TLC-?
