Even though the ether extract has fewer antioxidants, the ones it has stick better to the oil because they’re more oil-friendly, which helps protect it.
Scientific Claim
The LogP values of tocopherols in ethyl ether extract are higher than those of phenolic compounds in methanol extract, suggesting greater hydrophobic compatibility with avocado oil despite lower total phenolic content.
Original Statement
“The hydrophobic interaction of α and β-tocopherol (LogP: 8.27 (α); 7.79 (β)) in OE was greater than that shown by gallic acid (LogP: 0.21), catechin (LogP: 0.83), rutin (LogP: -1.12), and p-cumaric acid (LogP: 1.26) in OM.”

Assessment Explanation
The claim is based on calculated physicochemical properties (LogP) derived from molecular structures and reported in the study. It describes a plausible mechanism without overextending to unmeasured biological effects.
Evidence from Studies
Supporting (0)
Contradicting (1)
The study found that the methanol extract worked way better to protect avocado oil than the ethyl ether one, even though it has more water-friendly chemicals—so the idea that the ethyl ether version is more compatible with oil is wrong.
Technical explanation
The study does not measure LogP values of tocopherols or compare hydrophobic compatibility of tocopherols in ethyl ether versus phenolic compounds in methanol extracts. Instead, it compares total phenolic content (4100.9 ppm in methanol vs. 83.7 ppm in ethyl ether) and antioxidant activity (19,452.5 vs. 5091.6 µmol Trolox eq/g), showing methanol extracts are far richer in phenolics and more effective at stabilizing avocado oil. The claim incorrectly suggests ethyl ether extracts have higher LogP values and greater hydrophobic compatibility, but the study shows methanol extracts—despite being more polar—provide superior thermal stability. This contradicts the claim’s implication that ethyl ether’s lower phenolic content implies better oil compatibility. No data on tocopherols or LogP are presented, making the claim unsupported and misleading.
