Summary
This summary is machine-generated.The chemical composition of Centaurea thracica inflorescences changes during vegetation, with increased carbohydrates and fibers. Seed oils are rich in oleic and palmitic acids, indicating potential nutritional value.
Area Of Science
- Phytochemistry
- Plant Physiology
- Nutritional Science
Background
- Centaurea thracica is a plant native to southern Bulgaria.
- Understanding its chemical composition is crucial for potential applications.
Purpose Of The Study
- To analyze the chemical and lipid composition of Centaurea thracica inflorescences during vegetation.
- To compare the lipid profiles of inflorescences and seeds.
Main Methods
- Collection of inflorescences and seeds in June and September 2021.
- Chemical analysis of total proteins, glyceride oils, ash, carbohydrates, and fibers.
- Gas chromatography for fatty acid profiling.
- Quantification of tocopherols and phospholipids.
Main Results
- Inflorescences showed decreased proteins, oils, and ash, with increased carbohydrates and fibers during vegetation.
- Oleic and linoleic acid content in inflorescences increased significantly, while palmitic acid decreased.
- Seed lipids were rich in oleic (53.0%) and palmitic (36.2%) acids.
- Tocopherol content increased in inflorescence oils during vegetation and was high in seed oils (260 mg/kg).
- Phospholipid content decreased during vegetation, with compositional differences between inflorescences and seeds.
Conclusions
- The chemical composition of Centaurea thracica inflorescences changes significantly during vegetation.
- The oils from Centaurea thracica, particularly from seeds, possess high nutritional and biological value due to oleic acid, linoleic acid, tocopherols, and phospholipids.
- These findings suggest potential applications for Centaurea thracica oils in various industries.
