This plant extract is way more powerful at fighting free radicals than most other wild berries tested in similar lab tests.
Scientific Claim
The antioxidant activity of methanol extract of Aristotelia chilensis leaves (19,452.5 µmol Trolox eq/g) exceeds the antioxidant capacity of most wild fruits previously measured by the ORAC method (519.2–854.8 µmol Trolox eq/g).
Original Statement
“The values reported in this study are higher than those obtained for other wild fruits calculated by the ORAC method, which ranged from 519.2 to 854.8 μmol Trolox Eq/g dry wt.”
Evidence Quality Assessment

Appropriate Language Strength
definitive
Can make definitive causal claims
Assessment Explanation
The claim reports a direct numerical comparison between the study’s ORAC result and published values from other studies. No causal or health claims are made, only a quantitative benchmark.
Evidence from Studies
Supporting (1)
The study found that a leaf extract from a Chilean berry has way more antioxidant power than most wild fruits — like 20 times more — which matches the claim perfectly.
Technical explanation
The study directly reports that the methanol extract of Aristotelia chilensis (maqui) leaves has an antioxidant activity of 19,452.5 µmol Trolox eq/g, measured via the ORAC method. This value is significantly higher than the range of 519.2–854.8 µmol Trolox eq/g cited in the claim for most wild fruits. The study’s methodology (ORAC) aligns with the claim’s benchmark, and the extract’s antioxidant capacity is explicitly quantified, allowing direct comparison. The study does not measure other wild fruits, but it provides a single, highly elevated value that clearly exceeds the upper limit of the claimed range. Therefore, the evidence supports the claim that this extract’s antioxidant activity exceeds that of most previously measured wild fruits by ORAC.
