Comparative Analysis of Phenolic, Carotenoid, and Elemental Profiles in Three Species from Şebinkarahisar, Türkiye: Implications for Nutritional Value and Safety.

This study evaluated the phenolic, carotenoid, and elemental compositions of three hawthorn species- (yellow), (orange), and (red)-collected from Şebinkarahisar, Türkiye. Liquid chromatography tandem mass spectrometry (LC-MS-MS) analysis revealed that had the highest phenolic content, notably epicatechin, gallic acid, and quercetin. It also showed the highest levels of β-carotene and lutein, highlighting its nutraceutical potential. was rich in rutin and taxifolin. Inductively coupled plasma mass spectrometry (ICP-MS) results showed significant mineral content, including Fe, Mn, Ca, and Se. About 60 g of dried hawthorn could meet 7-8% of daily selenium needs. In , toxicological tests showed no substantial health hazards, with target hazard quotient (THQ) values below 1 and carcinogenic risk (CR) values within tolerable levels (e.g., Ni-CR: 4.68 × 10). Lead (Pb) and arsenic (As) levels were below detection thresholds in all samples, indicating that hawthorn fruits from this location are safe. The study also shows how species-specific and geographical factors affect hawthorn fruit nutrition and safety.
