The Claim
The unsaponifiable matter from pumpkin seed oil exhibits significantly higher antioxidant activity in the DPPH assay compared to other seed oils studied, with supercritical fluid extraction using CO2 yielding samples that demonstrate 39–50% free radical scavenging, which is correlated with elevated concentrations of squalene and cycloartenol.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Pumpkin seed oil extract contains compounds called squalene and cycloartenol that remove 39–50% of free radicals in laboratory tests, and this antioxidant effect is stronger than that of other seed oils tested under the same conditions.
See the scientific wording
The antioxidant activity of unsaponifiable matter from pumpkin seed oil is significantly higher than that of other seed oils studied, with SFE-CO2-extracted samples showing 39–50% free radical scavenging in the DPPH assay, correlating with higher levels of squalene and cycloartenol.
Squalene and cycloartenol molecules in pumpkin seed oil give up hydrogen atoms to stop harmful free radicals from damaging cells, making them more effective at fighting oxidation than similar compounds in other seed oils.
What the research says
1 studyPumpkin seed oil extracted with supercritical CO2 has more healthy compounds that fight free radicals than other seed oils tested, and this is because of higher levels of squalene and cycloartenol — exactly what the claim says.
