When testing botanical ingredients of herbal medicines and dietary supplements, the complexity of botanical matrixes often requires the use of orthogonal methods to establish identification procedures suitable for quality control purposes. Genomic-based botanical identification methods are evolving and emerging as useful quality control tools to complement traditional morphological and chemical identification methods. Species-specific polymerase chain reaction methods are being evaluated for botanical quality control and as a cost-effective approach to identify and discriminate between closely related botanical species. This paper describes orthogonal identification of Panax ginseng, P. quinquefolius, and P. notoginseng materials in commerce as an example of the development and validation of a set of species-specific polymerase chain reaction methods to establish botanical identity in ginseng roots. This work also explored the possibility of extending the application of species-specific polymerase chain reaction methods to provide species identity information for processed materials, such as steamed roots and hydroalcoholic extracts, and showed success with this approach. Finally, the paper provides recommendations for an out-of-specification investigation of samples that may pass some of the orthogonal tests and fail others.

使用正交方法鉴定人参物种的物种特异性 PCR 方法的开发和验证

在测试草药和膳食补充剂的植物成分时,植物基质的复杂性通常需要使用正交方法来建立适合质量控制目的的鉴定程序。基于基因组的植物鉴定方法正在发展并成为有用的质量控制工具,以补充传统的形态学和化学鉴定方法。物种特异性聚合酶链反应方法正在评估用于植物质量控制,并作为一种经济有效的方法来识别和区分密切相关的植物物种。本文描述了人参、西洋参和西洋参的正交鉴定。商业中的三七材料作为开发和验证一组物种特异性聚合酶链反应方法以在人参根中建立植物特性的示例。这项工作还探索了扩展物种特异性聚合酶链反应方法的应用的可能性,以提供加工材料(如蒸根和水醇提取物)的物种身份信息,并证明了这种方法的成功。最后,本文提供了对可能通过一些正交试验而其他试验失败的样品进行不合格调查的建议。这项工作还探索了扩展物种特异性聚合酶链反应方法的应用的可能性,以提供加工材料(如蒸根和水醇提取物)的物种身份信息,并证明了这种方法的成功。最后,本文提供了对可能通过一些正交试验而其他试验失败的样品进行不合格调查的建议。这项工作还探索了扩展物种特异性聚合酶链反应方法的应用的可能性,以提供加工材料(如蒸根和水醇提取物)的物种身份信息,并证明了这种方法的成功。最后,本文提供了对可能通过一些正交试验而其他试验失败的样品进行不合格调查的建议。
