Extraction method	Efficiency (%)		Concentration of sterols (%)	Concentration of tocopherol (%)
Extraction method	Phytosterols	Tocopherols	Concentration of sterols (%)	Concentration of tocopherol (%)
Modified Soxhlet	24 ± 1^d^∗		10 ± 0.2^d	11 ± 1^d
Raw RODD + SCF (100% CO₂)	71 ± 3^c	82 ± 2^c	51 ± 1^c	60 ± 1^c
SCF(95% CO₂+ 5% ethanol)	81 ± 4^a	91 ± 1^a	67 ± 3^a	83 ± 1^a
Saponified RODD + SCF(95% CO₂+ 5% ethanol)	76 ± 1^b	84 ± 1^b	60 ± 2^b	74 ± 0.3^b

Non-similar letters in each column indicate a significant difference according Tukey test (P<0.05).
