Chemical and Bioactivity Analysis of Ebony Leaf Extracts

A research study characterizing secondary metabolites from 50% ethanol extracts of Diospyros celebica (ebony) leaves. The work includes analysis of total phenolic and flavonoid content, antioxidant activity, and α-glucosidase inhibition, with specific IC50 values reported for fractions and an isolated compound. The dataset, authored by Sausan Afra and last updated in April 2026, consists of supporting documents in PDF and DOCX formats.

Use Cases

• Identify potential natural antioxidant compounds based on reported DPPH IC50 values.
• Screen for plant-derived α-glucosidase inhibitors based on reported inhibition IC50 values.
• Study the correlation between phenolic/flavonoid content and bioactivity as described in the analysis.
• Investigate the chemical profile of Diospyros celebica extracts based on LC-HRMS results mentioned.

Strengths

• Reports specific quantitative bioactivity results (e.g., DPPH IC50 = 9.07 μg/mL, α-glucosidase IC50 = 4.98 μg/mL).
• Identifies a specific isolated compound (epiafzelechin-3-O-gallate) with its measured bioactivity.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• The core data is embedded within PDF/DOCX documents; column-level documentation is absent and data must be extracted manually.
• Row count and structured tabular data are unknown, which may limit suitability assessment.
• The dataset's 2.1 MB size suggests it contains documentation rather than a large-scale experimental data repository.
