Validated chromatographic analyses revealed considerable variation among cultivars. AR levels, particularly heneicosylresorcinol, showed relatively consistent patterns across years, whereas the concentrations of phytosterols, vitamin E, and carotenoids varied more noticeably between years, suggesting possible associations with environmental conditions. Hierarchical clustering analysis classified the cultivars into five distinct groups according to their overall phytochemical profiles. \u2018Dajoong\u2019 and \u2018Shinmichal\u2019 exhibited the highest AR levels; \u2018Hanbaek\u2019, \u2018Goso\u2019, and \u2018Joah\u2019 were richest in \u03b2-sitosterol; \u2018Eunpa\u2019 and \u2018Namhae\u2019 showed elevated \u03b2-tocotrienol content, while \u2018Uri\u2019 and \u2018Chungkye\u2019 were notable for high lutein concentrations. \u2018Saekeumkang\u2019 displayed a balanced profile across all phytochemical classes. These findings provide baseline data on phytochemical variation among Korean wheat cultivars and offer insight into differences in phytochemical diversity.<\/jats:p>","DOI":"10.3390\/foods15061075","type":"journal-article","created":{"date-parts":[[2026,3,19]],"date-time":"2026-03-19T11:50:36Z","timestamp":1773921036000},"page":"1075","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Analysis of Alkylresorcinol, Phytosterol, Carotenoid, and Vitamin E Contents in Korean Wheat Cultivars"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1117-4068","authenticated-orcid":false,"given":"Huijin","family":"Heo","sequence":"first","affiliation":[{"name":"Department of Food Science and Biotechnology, Chungbuk National University, Cheongju 28644, Chungbuk, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3608-7246","authenticated-orcid":false,"given":"Seonghwa","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Food Science and Biotechnology, Chungbuk National University, Cheongju 28644, Chungbuk, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinhee","family":"Park","sequence":"additional","affiliation":[{"name":"Wheat Research Team, National Institute of Crop Science, Wanju 55365, Jeonbuk, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyeong-Hoon","family":"Kim","sequence":"additional","affiliation":[{"name":"Wheat Research Team, National Institute of Crop Science, Wanju 55365, Jeonbuk, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0349-4483","authenticated-orcid":false,"given":"Heon-Sang","family":"Jeong","sequence":"additional","affiliation":[{"name":"Department of Food Science and Biotechnology, Chungbuk National University, Cheongju 28644, Chungbuk, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4059-4195","authenticated-orcid":false,"given":"Hana","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Food Science and Biotechnology, Chungbuk National University, Cheongju 28644, Chungbuk, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5557-4229","authenticated-orcid":false,"given":"Junsoo","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Food Science and Biotechnology, Chungbuk National University, Cheongju 28644, Chungbuk, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Kumar, V., Kumar, M., Sharma, S., and Prasad, R.
