双分子标记法的构建及在中药研究中的应用

该文针对作者之前提出的分子鉴定中真伪鉴别有余,优劣评价不足的现象,以及中药材二维分子标记法构建中功能基因研究基础薄弱的情况,提出了基于DNA分子标记和代谢标识物相结合的双分子标记法(bimolecular marking methods,简称BIMM),能满足现阶段在分子水平同时研究中药的种类和质量差异.该文系统介绍了双分子标记法的概念、原理、方法和技术流程,总结了该方法所具备的技术优势,展望了其在中药多来源药材的鉴别研究、年限鉴别研究、产地鉴别研究、优良种质研究、新的药物资源的寻找和开发及中药植物新品种保护中的重要应用.作为中药材二维分子标记法的补充,双分子标记法的提出,将进一步促进分子水平对中药的真伪鉴定及质量优劣评价研究的发展.

Hypothesis and application of bimolecular marking methods in Chinese materia medica

Based on the current shortage of genuine/false authentication and quality evaluation in the molecular identification, and the weak functional gene research in the establishment of two-dimensional molecular markering methods for Chinese materia medica, the authors proposed a new method, the bimolecular marking methods (BIMM) for Chinese materia medica, combining DNA marker and metabolomics marker, that could simultaneously research the species and quality differences at the molecular level at the present stage.The authors introduced the concept, principle, methods, and technical process of BIMM, and summarized the technical advantages in this paper.Meanwhile, the application of BIMM in the identification of multiple sources of Chinese materia medica, years-identification, different locations, elite germplasm research, discovery of new drugs resources, protection of new varieties was also discussed.As a supplement of two-dimensional molecular markering method for Chinese materia medica, BIMM would not only expand connotation of identification of Chinese materia medica but also provide another effective way for quality evaluating.
