Although they have been extensively studied in many species of the genus Rosa L., garden roses&rsquo: hips have largely been overlooked. To investigate their potential use in the food industry, this study evaluated five cultivars from &lsquo:Aurora&rsquo: collection: &lsquo:Purple Aurora&rsquo:, &lsquo:Berry Bush Aurora&rsquo:, &lsquo:Aromatic Aurora&rsquo:, &lsquo:Butterfly Aurora&rsquo:, and &lsquo:Rugose White Aurora&rsquo:. Morphological characterization, along with the assessment of the phenolic profile, vitamin C levels, and biological activities&mdash:including antioxidant and neuroprotective effects&mdash:was conducted. The fruit mass reached 5.15 g, while the mesocarp mass ranged from 3 to 4 g, resulting in a mesocarp-to-fruit ratio of over 75%. The total phenolic content ranged from 37.1 to 63.9 mg GAE/g de, while total flavonoids were present in amounts from 0.85 to 2.14 mg QE/g de. Rosehip extracts from four out of five cultivars exhibited a very high vitamin C content, reaching 2384 µ:g/g fw. Quinic acid and 31 phenolic compounds were found in the rosehip extract of at least one cultivar. Results indicated &lsquo:Aurora&rsquo: rosehips have potent antioxidant properties and a moderate inhibitory effect on acetylcholinesterase, highlighting their potential as a source of functional food. Additional research is needed to fully leverage these benefits and establish garden rosehips as a viable alternative to synthetic antioxidants.
