Absolute Configuration of Solenopsis Piperidines is a Tool to Classify Fire Ants (Formicid

Piperidine alkaloids from the venom glands of Solenopsis invicta and S. saevissima fire ants were analyzed. Francisca Diana da Silva Araújo determined the absolute configuration of 2,6-dialkyl-piperidines using chiral gas chromatography with a flame ionization detector (GC-FID). The data groups Southeastern Brazil species based on stereoisomer profiles, showing S. saevissima produces four stereoisomers of specific piperidines while S. invicta venom primarily consists of a single enantiomer.

Use Cases

• Classifying fire ant species based on piperidine alkaloid stereoisomer profiles mentioned in the description
• Developing chemotaxonomic identification keys for sympatric ant species using venom chemistry data
• Analyzing the relationship between venom chemical configuration and ant species in Southeastern Brazil

Strengths

• Data derived from chiral gas chromatography (GC-FID) analysis, a precise analytical method
• Focus on sympatric species in Southeastern Brazil provides a specific geographic context for classification

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Last update date is unknown; freshness unverified
