This study is the first report on the determination and quantification of scopoletin using quantitative nuclear magnetic resonance (qNMR) in the different extracts of Paederia foetida twigs. The validated qNMR method showed a good linearity (r2 = 0.9999), limit of detection (LOD) (0.009 mg\/mL), and quantification (LOQ) (0.029 mg\/mL), together with high stability (relative standard deviation (RSD) = 0.022%), high precision (RSD &lt; 1%), and good recovery (94.08\u2013108.45%). The quantification results of scopoletin concentration in chloroform extract using qNMR and microplate ultraviolet-visible (UV-vis) spectrophotometer was almost comparable. Therefore, the qNMR method is deemed accurate and reliable for quality control of Paederia foetida and other medicinal plants without extensive sample preparation.<\/jats:p>","DOI":"10.3390\/molecules25215162","type":"journal-article","created":{"date-parts":[[2020,11,8]],"date-time":"2020-11-08T20:23:35Z","timestamp":1604867015000},"page":"5162","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Rapid Quantification and Validation of Biomarker Scopoletin in Paederia foetida by qNMR and UV\u2013Vis for Herbal Preparation"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5578-3415","authenticated-orcid":false,"given":"Dai Chuan","family":"Tan","sequence":"first","affiliation":[{"name":"Department of Chemistry, Faculty of Science, Universiti Putra Malaysia, UPM Serdang 43400, Selangor, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandra","family":"Quek","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Faculty of Science, Universiti Putra Malaysia, UPM Serdang 43400, Selangor, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nur Kartinee","family":"Kassim","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Faculty of Science, Universiti Putra Malaysia, UPM Serdang 43400, Selangor, Malaysia"},{"name":"Integrated Chemical BioPhysics Research, Faculty of Science, Universiti Putra Malaysia, UPM Serdang 43400, Selangor, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3960-0022","authenticated-orcid":false,"given":"Intan Safinar","family":"Ismail","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Faculty of Science, Universiti Putra Malaysia, UPM Serdang 43400, Selangor, Malaysia"},{"name":"Natural Medicines and Product Research Laboratory, Institute of Biosciences, Universiti Putra Malaysia, UPM Serdang 43400, Selangor, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4626-5894","authenticated-orcid":false,"given":"Joanna Jinling","family":"Lee","sequence":"additional","affiliation":[{"name":"Laboratory of Molecular Biomedicine, Institute of Bioscience, Universiti Putra Malaysia, UPM Serdang 43300, Selangor, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"S1","DOI":"10.5694\/j.1326-5377.2006.tb00548.x","article-title":"Health benefits of herbs and spices: The past, the present, the future","volume":"185","author":"Tapsell","year":"2006","journal-title":"Med.
