Recently, Gornaset al. [13] reported that β- and c-tocopherols are pre-dominated homologues in acorn oils from Q. rubra andQ. robur. *e total concentration of tocopherols in Q. roburacorn oil was 447.7 mg/100 g oil, whereas the concentrationin Q. rubra acorn oil was 78.4 mg/100 g oil.

However, [13] reportedthat β–tocopherol was the main tocopherol in Q. rubraacorn oils (93% of the total detected tocopherols), which is aunique phenomenon within not only acorn species but alsoother plant species.
