Star Anise Oil Extraction and Cycloaddition Reaction Data for Chemistry Education

An integrated undergraduate laboratory sequence details the extraction of trans-anethole from star anise and its use in synthesizing 3,5-diarylisoxazolines. The 13.4 MB dataset includes procedures and characterization data from proton and carbon-13 NMR, FTIR, HRMS, and SC-XRD analysis. It was authored by Itamar Luís Gonçalves and last updated on 2026-05-21.

Use Cases

• Teaching essential oil extraction techniques based on the described steam distillation process.
• Demonstrating spectroscopic characterization workflows based on the included NMR, FTIR, and HRMS data.
• Illustrating (3+2) 1,3-dipolar cycloaddition reactions based on the synthesis of 3,5-diarylisoxazolines.
• Structuring modular laboratory courses based on the described two-phase experimental design.

Strengths

• Includes multi-technique structural characterization data from NMR, FTIR, HRMS, and SC-XRD.
• Describes a complete, modular experimental sequence from extraction to synthesis.
• Specifically designed for students in Chemistry, Pharmacy, and Chemical and Food Engineering.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 13.4 MB size suggests a small-scale dataset, potentially limiting analysis scope.
