Papaver Umbonatum Alkaloid Extract: Antibacterial and Antioxidant Bioactivity

Papaver umbonatum Boiss was investigated for its alkaloid profile, antibacterial, and antioxidant activities. The dataset likely contains results from the isolation and identification of alkaloids, including isopavine, promorphinane, and the first-reported O-methylflavinantine in the genus. It also includes quantitative bioactivity assays measuring minimum inhibitory concentration (MIC), antibiofilm activity against Gram-positive bacteria, and antioxidant activity via DPPH free radical scavenging.

Use Cases

• Identifying novel alkaloids based on 1H-NMR analysis results
• Comparing antibacterial efficacy (MIC) against Enterococcus faecalis and Bacillus subtilis
• Evaluating antibiofilm activity at specific concentrations (e.g., 10 µg/mL, 625 µg/mL)
• Assessing antioxidant potential of plant extracts using DPPH assay data
• Validating the first reported occurrence of O-methylflavinantine in Papaver

Strengths

• Contains first-reported identification of O-methylflavinantine in the Papaver genus
• Provides specific quantitative bioactivity results (e.g., MIC, antibiofilm concentrations of 10 µg/mL and 625 µg/mL)
• Released under a permissive CC-BY-4.0 license for reuse

Limitations

• Column names and exact data structure are not provided, limiting immediate usability
• The dataset size (979701 bytes) is known, but the row count is unspecified
• Metadata is sparse, lacking information on the organization and specific data collection methodology
