Summary
This study describes the preparative HPLC-based isolation of flavonoid-enriched fractions from two Chilean native berries, maqui and murta, and characterises their anti-inflammatory potential in vitro. The research likely identifies specific flavonoid classes responsible for bioactive effects, contributing to the phytochemical characterisation of these underutilised Patagonian fruit species. Findings are expected to inform potential nutraceutical or functional food applications, though in vivo confirmation would be required to establish clinical relevance.
UK applicability
Maqui and murta are not cultivated commercially in the UK, so direct agronomic applicability is limited; however, the methodological approach to isolating and characterising bioactive flavonoid fractions from berry crops is broadly relevant to UK interest in native and novel berry species, as well as to the development of functional food ingredients from polyphenol-rich fruits.
Key measures
Flavonoid fraction composition (HPLC profile); anti-inflammatory markers in cell-based assays (likely cytokine levels, e.g. IL-6, TNF-α, or similar inflammatory mediators); possibly cell viability metrics
Outcomes reported
The study isolated flavonoid-enriched fractions from maqui (Aristotelia chilensis) and murta (Ugni molinae) using preparative HPLC and evaluated their anti-inflammatory effects using cell-based assays, likely measuring markers such as cytokine production or NF-κB pathway activity in stimulated cell lines.
