太赫兹时域光谱技术在中药鉴别中的研究进展

Progress of Terahertz Time-domain Spectroscopy in Identification of Traditional Chinese Medicine

频率介于0.1~10THz的太赫兹技术反映了物质分子振动和转动层面的信息,太赫兹指纹图谱对中药复杂成分的鉴别及其质量评估具有特殊的优越性。本文简要介绍了太赫兹时域光谱技术,综述了近年来太赫兹时域光谱技术在中药鉴别方面的应用,最后对该技术在中药研究中存在的问题和发展前景进行了探讨。

Terahertz time-domain spectroscopy(THz-TDS)which the spectrum frequency settled from 0.1 to 10 THz is a useful tool for reflecting the information about molecular vibration and rotation.The THz-TDS has a particular advantage for identification of traditional Chinese medicines which its component is very complex.In this pater,the principle of THz-TDS is given,and the applications for identification of traditional Chinese medicines in recent years are overviewed.The difficulties of THz-TDS in the research field of traditional Chinese medicines are discussed and the prospect in this field is described also.
