Olive Leaf Oleuropein Extraction Data with Antioxidant Oil Tests

Experimental data from a study extracting oleuropein from olive leaves using hydroalcoholic solvents. The work was conducted by Carolina Fernanda Sengling Cebin Coppa at Universidade de São Paulo. The highest oleuropein content found was approximately 18 g per 100 g of freeze-dried extract.

Use Cases

• Modeling oleuropein yield based on solvent-to-leaf mass ratios and acetic acid presence.
• Analyzing the antioxidant effect of olive leaf extracts on olive oil oxidative stability.
• Comparing extraction efficiency of renewable hydroalcoholic solvents for bioactive compounds.

Strengths

• Reports specific quantitative results, including an oleuropein content of approximately 18 g/100 g.
• Describes controlled experimental variables such as OL:S mass ratios (1:8, 1:6, 1:3) and acetic acid presence.
• Includes a practical application test showing increased induction times (3 and 2 hours) in olive oil samples.

Limitations

• Row count and dataset scale are 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.
