Despite having a wealth of bioactive compounds with significant commercial and nutraceutical potential, citrus by-products, including peels, seeds, and pulp, are routinely discarded in large amounts. In this study, we examine the nutritional composition, elemental diversity, metabolite profile, and genetic variability of citrus species collected from various regions of Uttarakhand, India. Citrus peels are a good source of calcium (up to 104.10mg\/100\u00a0g), zinc (58.3 mg\/100\u00a0g), manganese (22.1 mg\/100\u00a0g) and so on, as well as proteins (12.00\u00a0\u00b1\u00a00.11\n                    <jats:sup>a<\/jats:sup>\n                    ), reducing and non-reducing sugar (136.45 \u00b1 .001\n                    <jats:sup>a<\/jats:sup>\n                    and 26.53\u00a0\u00b1\u00a0S1.123\n                    <jats:sup>a<\/jats:sup>\n                    ), and vitamin C (65.56\u00a0\u00b1\u00a00.23\n                    <jats:sup>a<\/jats:sup>\n                    ), according to elemental and nutritional analyses. On GC analysis, more than 45 bioactive compounds were identified, including rutin, limonene, linoelaidic acid, and palmitic acid.\n                    <jats:italic>Citrus jambhiri<\/jats:italic>\n                    (Almora) has the highest (51) phytochemicals, whereas\n                    <jats:italic>Citrus sinensis<\/jats:italic>\n                    (Pithoragarh) exhibits the lowest (27) phytochemicals. On genetic analysis, the accessions\u2019 great diversity was further highlighted by a genetic analysis using Simple Sequence Repeat (SSR) markers, which showed grouping patterns related to species and geographic origin. Integrating biochemical, metabolite, and genetic data reveals a strong genotype\u2013environment interaction that influences the nutritional and nutraceutical properties of citrus species. The study provides information that can aid in the development of functional foods, pharmaceutical applications, and crop enhancement methods while highlighting the potential of citrus by-products as sustainable sources of valuable bioactive compounds.\n                  <\/jats:p>","DOI":"10.3389\/fpls.2025.1703245","type":"journal-article","created":{"date-parts":[[2025,12,8]],"date-time":"2025-12-08T06:30:27Z","timestamp":1765175427000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["From byproduct to bioactive: genetic profiling, GC-MS, and nutritional analysis of citrus peel extracts for nutraceutical development"],"prefix":"10.3389","volume":"16","author":[{"given":"Om","family":"Prakash","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Divya","family":"Kushwaha","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kahkashan","family":"Perveen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shaista","family":"Arzoo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saurabh","family":"Gangola","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vijay Kumar","family":"Juyal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shifa","family":"Khan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Vivekananda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2025,12,8]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"65","DOI":"10.9734\/EJNFS\/2021\/v13i230376","article-title":"Antioxidant compounds and health benefits of citrus fruits","volume":"13","author":"Abakpa","year":"2021","journal-title":"European journal of nutrition & food safety"},{"key":"B2","doi-asserted-by":"publisher","first-page":"9443","DOI":"10.1039\/d1fo01905h","article-title":"Orange fruit (Citrus sinensis) peel extract attenuates chemotherapy-induced toxicity in male rats","volume":"12","author":"Abdelghffar","year":"2021","journal-title":"Food Funct."},{"key":"B3","doi-asserted-by":"publisher","first-page":"803","DOI":"10.1016\/j.jasms.2007.01.001\"10.1016\/j.jasms.2007.01.001","article-title":"Review of identification of essential oil components by gas chromatography\/mass spectrometry","volume":"18","author":"Adams","year":"2007","journal-title":"J.
