摘要: 中药是我国宝贵的资源,在疾病治疗、养生保健方面扮演着重要的角色。然而近年来,因鉴定方法不完善导致的中药安全事件屡屡出现,给中药临床应用带来极大挑战。传统的鉴定方法是中药药师凭借其长期积累的经验对中药材进行鉴定,虽然方法日趋完善,但其存在较大主观性,不可否认仍有它的局限性。科学技术不断发展完善,新技术、新方法也推动着中药鉴定学的发展,将传统的鉴定方法与现代的鉴定方法合理的结合在一起使用,才能对中药材进行更准确、科学的鉴定。近年来,高通量测序技术的发展,为分子标记技术的发展提供了良好的平台,为中药材的鉴定提供了更加准确可靠的手段。目前RAPD、AFLP、RFLP、SSR是应用最广泛的几种分子标记技术,各有其优缺点。SSR指的是基因组中由1-6个核苷酸组成的基本单位重复多次构成的一段DNA,SSR标记具有特异性高、重复性好、结果可靠、操作简单、对DNA要求不高等特点,在中药材的品种鉴定、植物种质鉴定、遗传图谱构建、遗传多样性分析等方面发挥着越来越重要的作用。对近年来SSR标记技术在中药鉴定中的应用作简要概述,旨在为该技术在中药材鉴定方面的进一步研究提供参考。

Abstract: Chinese medicine is a precious resource and plays an important role in disease treatment and health care in our daily life. However,in recent years,the safety incidents from using traditional Chinese medicines due to inappropriate identification methods have repeatedly occurred,which has brought huge challenges to the clinical application of traditional Chinese medicines. The traditional identification method is that traditional Chinese medicine pharmacists identify Chinese medicinal materials via applying their long-term accumulated experiences. Although the method is getting more and more perfect,it is still subjective and undeniably has its limitations. With the development of science and technology,new technologies and new methods promote the development of the identification of traditional Chinese medicines;the traditional identification methods can be reasonably combined with modern identification methods,and more accurate and scientific identification of Chinese herbal medicines can be achieved. The recent development of high-throughput sequencing technology has provided a favorable platform for the development of molecular marker technology and a more accurate and reliable means for the identification of Chinese herbal medicines. Currently,RAPD,AFLP,RFLP,and SSR are the several molecular markers most widely used,each of them has its own advantages and disadvantages. SSR refers to a piece of DNA consisting of multiple repeated units of 1-6 nucleotides in the genome. The SSR marker characterizes of high specificity,fine repeatability,reliable results,simple operation,and low DNA requirements,and thus plays an increasingly important role in the variety identification of Chinese medicinal materials,plant germplasm identification,genetic map construction,and genetic diversity analysis. The application of SSR marker technique in the identification of traditional Chinese medicine in recent years is briefly summarized here,aiming at providing a reference for the further application of this technique in the identification of traditional Chinese medicine.
