The developed method exhibited good linearity over the concentration range of 0\u201312 \u03bcg\/mL at both 269.7 nm and 252 nm. At 269.7 nm, the R2 values were 0.9963 and 0.9964 for ascorbic acid and resveratrol, with LOD\/LOQ values of 1.597\/4.838 \u03bcg\/mL and 1.563\/4.737 \u03bcg\/mL, respectively. At 252 nm, the corresponding R2 values were 0.9922 and 0.9995, while the LOD\/LOQ values were 2.537\/7.688 \u03bcg\/mL for ascorbic acid and 0.584\/1.771 \u03bcg\/mL for resveratrol. Percentage recovery rates of 50%, 100%, and 150% ranged from 98.6% to 100.6%, 98.5% to 100.4%, and 100.1% to 99.9%, respectively, with low %RSD values. %RSD of ascorbic acid and resveratrol combination, obtained during intra-day analysis, was 0.866% at \u03bb1 and 0.486% at \u03bb2. Inter-day test revealed a %RSD of 0.976% at \u03bb1 and 0.664% at \u03bb2, while repeatability was measured at 0.879 for \u03bb1 and 0.411 for \u03bb2, respectively. The developed UV method was simple, precise, and accurate for quantifying ascorbic acid and resveratrol in pure drugs in methanolic solution.<\/jats:p>","DOI":"10.17344\/acsi.2025.9651","type":"journal-article","created":{"date-parts":[[2026,11,7]],"date-time":"2026-11-07T10:18:08Z","timestamp":1794046688000},"page":"661-668","source":"Crossref","is-referenced-by-count":0,"title":["A validated UV spectrophotometric method for simultaneous determination of ascorbic acid and resveratrol using isosbestic point approach"],"prefix":"10.17344","volume":"73","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-9649-3376","authenticated-orcid":false,"given":"Rizwan","family":"Ahamad","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-8885-1740","authenticated-orcid":false,"given":"Nazreen","family":"Tabassum","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rama K","family":"P","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prerna","family":"Saxena","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3333-2672","authenticated-orcid":false,"given":"Mohd","family":"Akhtar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6797-3104","authenticated-orcid":false,"given":"Mohd","family":"Aqil","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7204-780X","authenticated-orcid":false,"given":"Mohd","family":"Mujeeb","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7072","published-online":{"date-parts":[[2026,9,25]]},"container-title":["Acta Chimica Slovenica"],"original-title":[],"deposited":{"date-parts":[[2026,11,7]],"date-time":"2026-11-07T10:18:16Z","timestamp":1794046696000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.matheo.si\/index.php\/ACSi\/article\/view\/9651"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9,25]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2026,9,25]]}},"URL":"https:\/\/doi.org\/10.17344\/acsi.2025.9651","relation":{},"ISSN":["1580-3155"],"issn-type":[{"value":"1580-3155","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,9,25]]}}}
