Chemical and Bioactivity Analysis of Two Fabaceae Pollen Samples Collected by Bees

Two pollen samples collected by Apis mellifera bees were analyzed for chemical composition and bioactivity. Palynological analysis showed the predominant pollen was from Fabaceae species (42.3% in sample I and 50.6% in sample II). The investigation, authored by Francisco Rodrigo de Lemos Caldas, identified specific polyamine derivatives and biflavonoids using UPLC-DAD-QTOF-MS/MS and reported antiradical and antimicrobial activities.

Use Cases

• Identifying polyamine derivatives and biflavonoids based on the UPLC-DAD-QTOF-MS/MS characterization described.
• Correlating antiradical activity with the presence of specific chemical compounds mentioned in the description.
• Correlating antimicrobial activity with the presence of specific chemical compounds mentioned in the description.
• Comparing chemical profiles between pollen samples with different Fabaceae percentages (42.3% vs 50.6%).

Strengths

• Chemical characterization was performed using UPLC-DAD-QTOF-MS/MS, a specific analytical technique.
• Identifies three putrescine derivatives, two spermidine derivatives, and four biflavonoids.
• Reports specific percentages of Fabaceae pollen in two samples (42.3% and 50.6%).
