Baill. Although the Chinese Pharmacopoeia makes a distinction at the medicinal material level, there is no reliable identification method for seeds. The existing approach still relies on traditional morphology, which requires rich experience.\n <\/jats:p>\n <\/jats:sec>\n \n Objectives<\/jats:title>\n This study aims to fill this gap and enable quality control at the source level.<\/jats:p>\n <\/jats:sec>\n \n Material and Methods<\/jats:title>\n \n A neighbor\u2010joining (NJ) tree based on the ITS2 gene was constructed to analyze species genetic relationships and find SNP site for\n \n S. chinensis<\/jats:italic>\n <\/jats:styled-content>\n . Primers targeting the SNP site were used in an allele\u2010specific PCR system, whose sensitivity was tested with different amounts of DNA and further validated by commercial samples.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n The NJ tree showed that\n \n S. chinensis<\/jats:italic>\n <\/jats:styled-content>\n clustered into a single strand, clearly separated from other related species. When the primers were applied to the allele\u2010specific PCR, a diagnostic 273\u2009bp band was amplified specifically in\n \n S. chinensis<\/jats:italic>\n <\/jats:styled-content>\n seeds, with no cross\u2010reactivity observed. This assay system exhibited high sensitivity, detecting as little as 0.5\u2009ng of genomic DNA, and was validated by commercial samples, suggesting its accuracy, reproducibility, and practical applicability.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n \n This method is an ideal tool for large\u2010scale seed authentication of\n \n S. chinensis<\/jats:italic>\n <\/jats:styled-content>\n due to its high efficiency, precision, and operational simplicity. Our research contributes to quality control throughout the supply chain by ensuring the purity of the seeds at the earliest stages of cultivation, and also promotes the standardized production of this valuable medicinal resource.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1002\/pca.70031","type":"journal-article","created":{"date-parts":[[2025,9,26]],"date-time":"2025-09-26T13:55:47Z","timestamp":1758894947000},"page":"117-126","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Identification of\n Schisandra chinensis<\/i>\n Seeds and Exclusion of Common Adulterants by Allele\u2010Specific PCR Based on ITS2 Sequences"],"prefix":"10.1002","volume":"37","author":[{"given":"Hui","family":"Tian","sequence":"first","affiliation":[{"name":"Heilongjiang Institute of Drug Control Harbin China"},{"name":"NMPA Key Laboratory for Quality Research and Evaluation of Traditional Chinese Medicine Harbin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yidi","family":"Yang","sequence":"additional","affiliation":[{"name":"Heilongjiang Institute of Drug Control Harbin China"},{"name":"NMPA Key Laboratory for Quality Research and Evaluation of Traditional Chinese Medicine Harbin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chi","family":"Ma","sequence":"additional","affiliation":[{"name":"Heilongjiang Institute of Drug Control Harbin China"},{"name":"NMPA Key Laboratory for Quality Research and Evaluation of Traditional Chinese Medicine Harbin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiuna","family":"Zhang","sequence":"additional","affiliation":[{"name":"Heilongjiang Institute of Drug Control Harbin China"},{"name":"NMPA Key Laboratory for Quality Research and Evaluation of Traditional Chinese Medicine Harbin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Fang","sequence":"additional","affiliation":[{"name":"Heilongjiang Institute of Drug Control Harbin China"},{"name":"NMPA Key Laboratory for Quality Research and Evaluation of Traditional Chinese Medicine Harbin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-0259-6669","authenticated-orcid":false,"given":"Fanna","family":"Qu","sequence":"additional","affiliation":[{"name":"Heilongjiang Institute of Drug Control Harbin China"},{"name":"NMPA Key Laboratory for Quality Research and Evaluation of Traditional Chinese Medicine Harbin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lihong","family":"Yang","sequence":"additional","affiliation":[{"name":"Heilongjiang Institute of Drug Control Harbin China"},{"name":"NMPA Key Laboratory for Quality Research and Evaluation of Traditional Chinese Medicine Harbin China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,9,26]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.3390\/genes10050397"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jep.2021.114759"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2008.09.070"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000034013"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.2174\/1386207325666220221093415"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1155\/2022\/3188292"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1093\/chromsci\/bmab083"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/jssc.202300302"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1080\/17512433.2021.1981859"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12906-024-04336-1"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jep.2024.119254"},{"issue":"20","key":"e_1_2_8_13_1","first-page":"5403","article-title":"Network Meta\u2010Analysis of Efficacy and Safety of Chinese Patent Medicines in Treatment of Insomnia","volume":"46","author":"Shi M.
