Folin\u2013Ciocalteu-reactive compounds were analyzed in peel, flesh, and whole-tuber samples from three seed propagation stages: minitubers (m1), standard tubers (m2), and first-class certified seed potatoes (E1), using the Folin\u2013Ciocalteu method. TPC was consistently highest in the peel, reaching 107.1 \u00b1 5.3 \u00b5g gallic acid equivalents (GAE) g\u22121 dry weight (DW) in VB Venta (m2), whereas the highest flesh TPC (86.7 \u00b1 4.3 \u00b5g GAE g\u22121 DW) was observed in VB Meda (E1). Across cultivars, peel TPC increased from 72.9 \u00b5g GAE g\u22121 DW in m1 to 85.6 \u00b5g GAE g\u22121 DW in E1. Whole-tuber TPC varied less among seed propagation stages (56.2\u201358.8 \u00b5g GAE g\u22121 DW). Because the seed propagation stages were produced under different cultivation conditions, the observed differences cannot be attributed solely to seed generation. The results confirm the higher concentration of Folin\u2013Ciocalteu-reactive compounds in potato peel and indicate its potential for further investigation as a source of bioactive compounds.<\/jats:p>","DOI":"10.3390\/molecules31173014","type":"journal-article","created":{"date-parts":[[2026,8,28]],"date-time":"2026-08-28T12:27:46Z","timestamp":1787920066000},"page":"3014","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Total Phenolic Content in Potato (Solanum tuberosum L.)
