引进近红外技术用于中药材品质的快速评价

近年来中药分析已经不再局限于仅仅提供分析方法,而更关注于包括本草学属性、药效成分和功效内涵等分析,即不仅分析物质的组成更要揭示其物质组成与功能的关系。近红外光谱分析技术以其独特的优势,目前在我国药物分析领域,特别是中药分析方面取得了较快发展。采用近红外光谱一方面可以全面地反映药材的整体信息,可用于鉴别和聚类分析。另一方面引入中药质量标志物的概念,通过筛选关键的药效成分,并通过化学计量学方法将光谱数据和其定量信息进行关联,可以实现对其中的多种药效成分同时进行定量分析。充分发挥近红外检测技术的优势,可以为中药材的质量快速评价提供更简便可靠的方法。该文从不同的侧面对近红外技术在中药材质量评价方面的进展和发展趋势进行了综述和讨论。

Rapid identification and evaluation of Chinese materia medica quality by near infrared spectroscopy

In recent years, the research object of traditional Chinese medicine(TCM) analysis has not just been limited to the common analysis technology, but focused on the key relationship between chemical ingredients and traditional functions, including Chinese material medica (CMM) attributes, chemical substance and biological function. Near infrared spectroscopy (NIR) analysis technology, due to its unique advantages, has been developed rapidly in the field of pharmaceutical analysis, especially in the TCM analysis. NIRS can reflect the global chemical information comprehensively, and this holistic approach can be used for the identification and cluster analysis of CMM. On the other hand, inspiring by the concept of TCM quality markers (Q-markers), by means of the activity screening assay of the key components from the CMM, multiple bioactive components quantitation can be achieved by the NIRS combined with chemometrics. Taking the full advantage of the NIR technology, a simple and reliable method for the fast evaluation of the quality of TCMs can be provided. Therefore, the progress and trend of modern TCM quality evaluation by NIR are discussed and prospected in the present review.
