In Vitro Functional Properties of Rosehips from 'Aurora' Edible Garden Rose's Collection.

Area of Science:

• Food Science
• Horticulture
• Nutraceuticals

Background:

• Garden rosehips (Rosa L.) are understudied compared to other Rosa species.
• Potential applications in the food industry remain largely unexplored.

Purpose of the Study:

• Evaluate five 'Aurora' collection garden rose cultivars for food industry potential.
• Characterize morphological traits, phenolic profiles, vitamin C, and biological activities.

Main Methods:

• Morphological characterization of rosehips.
• Quantification of total phenolics and flavonoids.
• Measurement of vitamin C content.
• Assessment of antioxidant and acetylcholinesterase inhibitory activities.

Main Results:

• High mesocarp-to-fruit ratio (>75%).
• Significant total phenolic content (37.1–63.9 mg GAE/g de) and flavonoids (0.85–2.14 mg QE/g de).
• Very high vitamin C content in four cultivars (up to 2384 µg/g fw).
• Presence of quinic acid and 31 phenolic compounds.
• Potent antioxidant properties and moderate acetylcholinesterase inhibition.

Conclusions:

• 'Aurora' rosehips demonstrate considerable nutritional value and bioactivity.
• Potential use as a natural source for functional foods and antioxidants.
• Further research recommended to validate and utilize these benefits.
