Table 2: Sterol content [mg/kg] from organic and conventionally firmed olive oils. Among the sterol fractions of the analyzed oils, \(\beta\)-sitosterol had the highest content, ranging from 476.08 to 774.79 mg/kg. \(\Delta\)5-avenasterol was the second most abundant sterol, with levels between 45.22 and 140.47 mg/kg, followed by campesterol, which ranged from 18.26 to 35.37 mg/kg (Table 2). Clerosterol had the lowest concentration among the identified sterols, ranging from 4.90 to 8.27 mg/kg. Additionally, the analysis revealed the presence of compounds from the triterpenene alcohol group. Cycloartenol was found in small amounts compared to 24-methylenedcycloartenol, which, after \(\beta\)-sitosterol, was the second most abundant sterol in the profile, ranging from 63.27 to 185.93 mg/kg (Table 2).
