Tabebuia Caraiba Phytochemical Compounds from Bark and Flowers

Aloízio de Oliveira Soares isolated and characterized chemical constituents from the trunk bark and flowers of Tabebuia caraiba. The dataset likely contains information on four novel iridoids, three known iridoids, six triterpenes, and other compounds identified using 1D/2D NMR and HPLC/DAD/HRESIMS techniques. The chemical profile from the bark showed a poor correlation with the isolated substances, suggesting the presence of additional non-isolated compounds.

Use Cases

• Identify novel iridoid structures based on NMR spectroscopic data mentioned in the description
• Compare chemical profiles between plant parts (bark vs. flowers) based on the described metabolite lists
• Validate HPLC/DAD/HRESIMS analysis methods against traditional phytochemical isolation results described
• Study the distribution of triterpenes like betulinic acid and ursolic acid in Bignoniaceae species

Strengths

• Includes data on four novel iridoid compounds specifically named in the description
• Compounds were structurally characterized using 1D and 2D NMR spectroscopic techniques
• Analysis employed multiple techniques: phytochemical study and HPLC/DAD/HRESIMS profiling

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Description metadata is limited; actual data quality requires manual inspection after download
