太赫兹时域光谱技术在中药鉴别中的应用进展

Progress on application of terahertz time-domain spectroscopy in identification of traditional Chinese medicine

随着中药材的需求日益增加,药材资源逐渐匮乏,药材以次充好、以假乱真的现象屡见不鲜,对中药材的鉴定技术要求也不断增高。太赫兹时域光谱(THz-TDS)技术是一种新兴的光谱技术,在影像、安保检查、生物检测、医药、材料技术、航天领域、石油开采等方面有了广泛的应用。THz-TDS技术可以对中药的基原、真伪、炮制品、农药残留等方面进行快速无误无损的检测,该技术对补充和完善中药质量标准将具有重要意义。该文总结了THz-TDS的组成原理及其鉴定中药的优势,同时介绍了该技术在中药鉴别领域中的应用现状与应用前景。

With the increasing demand for traditional Chinese medicines(TCMs),the resources of TCMs are gradually rare,and the phenomenon that TCMs fake is a common occurrence.Consequently,we need to urgently improve identification technique of TCMs.Terahertz time-domain spectroscopy(THz-TDS)is a newly emerging spectroscopy technology that has been widely used in image,security inspection,biological detection,medicine,material technology,aerospace,oil exploration and other fields.Which is currently used as a simple and quick method to identify the origins,fake products,processed products and pesticide residues of TCMs,hence,it plays a significant role in supplementing and improving the quality control levels of TCMs.In this paper,the composition principle of THz-TDS and its advantages in authentification of TCMs have been summarized.Additionally,the current situation and application prospects of THz-TDS in the field of TCM identification have also been reviewed.
