草药产品中的物种掺假使消费者面临健康风险。化学方法和形态学方法在处理HP中含有相同活性化合物的物种的检测时有其自身的不足。在这项研究中,我们开发了一种快速鉴定方法,使用重组酶聚合酶扩增(RPA)检测两个物种,银杏和国槐(作为掺假),银杏高压灭菌器。在36份银杏HP样本中,发现34份具有银杏序列,9份具有国槐序列。在鉴定过程中,RPA-LFS检测方法显示出比基于PCR的方法更高的特异性、灵敏度和效率。我们最初应用RPA-LSF技术来检测植物物种在HP中,表明该测定可以发展成为一种有效的工具,用于快速现场认证银杏HP中的植物物种。
Species adulteration in herbal products (HPs) exposes consumers to health risks. Chemical and morphological methods have their own deficiencies when dealing with the detection of species containing the same active compounds in HPs. In this study, we developed a rapid identification method using the recombinase polymerase amplification (RPA) assay to detect two species, Ginkgo biloba and Sophora japonica (as adulteration), in Ginkgo biloba HPs. Among 36 Ginkgo biloba HP samples, 34 were found to have Ginkgo biloba sequences, and 9 were found to have Sophora japonica sequences. During the authentication process, the RPA-LFS assay showed a higher specificity, sensitivity and efficiency than PCR-based methods. We initially applied the RPA-LSF technique to detect plant species in HPs, demonstrating that this assay can be developed into an efficient tool for the rapid on-site authentication of plant species in Ginkgo biloba HPs.
