白及的质量问题及真伪鉴别方法

目的：在调研和检验的基础上分析我国当前中药白及的市场质量问题，研究白及的真伪鉴别方法，为监管工作提供建议。方法：文献整理及产区、市场调研和检验数据相结合，分析白及质量问题及其产生的原因，同时提出解决方案。结果：同属植物或相似种掺伪为白及主要质量问题，2017年全国中药材及饮片专项抽验白及不合格率为9%。白及伪品种类复杂，单一检测技术难以鉴别，而组合特征技术可以有效区分白及正伪品。结论：虽然白及伪品种类繁多，但是其质量问题尚可。提升白及药材及饮片质量，应加强源头治理，从规范生产入手。

On Quality Problems and Authenticity Identification Methods of Bletillae Rhizoma

Objective: To analyze the current market quality problems on the basis of investigation and inspection, to study the authenticity identification methods of the traditional Chinese medicine (TCM) bletillae rhizoma and to provide suggestions for drug supervision. Methods: Literature reviews, investigation into the producing areas and markets, and the inspection data were combined to analyze the quality problems of bletillae rhizoma and their causes, and the solutions were put forward. Results: The main quality problems of bletillae rhizoma was the adulteration of the same genus or similar species. The percentage of unqualified bletillae rhizoma was 9% according to the national sampling inspection for the TCM crude drugs and prepared slices. It was difficult for the single detection method to authenticate the bletillae rhizoma due to the complex varieties of the fakes. However, the combined characteristic technologies can distinguish bletillae rhizoma from the fakes efficiently. Conclusion: Although there are a wide variety of counterfeit bletillae rhizoma, the quality problems are still acceptable. In order to improve the quality of the TCM crude drugs and prepared slices of bletillae rhizoma, we should strengthen the source management starting from standardized production.
