Unveiling Bioactive Compounds of Endemic Ornithogalum yesilyurtense: A First Comprehensive Study.

Key Points

• To analyze the phytochemical and pharmacological properties of endemic Ornithogalum yesilyurtense.
• Conducted phytochemical analysis using methanol extracts from aerial and bulb parts.
• Assessed antioxidant properties through ferric reducing power (FRAP) and DPPH tests.
• Utilized LC-MS/MS and GC-MS for detailed profiling of phenolic and fatty acid contents.
• Aerial parts had higher total phenolic content (0.194 mg GAE/g) compared to bulbs (0.148 mg GAE/g).
• Aerial parts exhibited superior antioxidant activity, with better FRAP (0.784 µM Fe²⁺/g) and lower DPPH IC₅₀ (1.645 µg/mL) values than bulbs.
• Dominant acids in aerial parts included palmitic, linolenic, and γ-linolenic acids, while bulbs were rich in cis-linoleic and palmitic acids.
