Key Findings
- HPLC method identified 8 phenolic acids in concentrated peat extract
- Phenolic profiles of extracts from different medicinal peats were similar, with variations in individual acid amounts
- Antioxidant activity evaluated by ABTS assay — differences observed between extracts from different peat varieties
- Antioxidant activity differences reflect phenolic composition
- Produced by Torf Corporation — Pharmaceutical Factory, Poland (TPP heritage)
First quantitative HPLC analysis of phenolic acids in concentrated peat extract. Identified 8 individual phenolic acids and measured antioxidant activity using the ABTS assay. Produced at the Torf Corporation (TPP heritage). Important because it provides the analytical chemistry behind peat’s antioxidant claims — moving from “peat has antioxidant activity” to “here are the specific compounds and their measured activity.” Listed as TIER 1 priority in papers-to-find.
