摘要

品种因素对初榨橄榄油甾醇成分组成的影响已被G.L.C.证实，这种成分既不受橄榄的不良条件影响，也不受油的自氧化过程的影响。与SE-30相比，OV-17等许多选择性固定相的使用并不能改善旨在保护原油真实性的分析情况。分析结果证实了官方方法的价值，即使在很少的油中-谷甾油含量不足的情况下，混合也是必要的。

[The sterolic fraction of virgin olive oil and its and its analytical significance].

The influence of the cultivar factor over the composition of the sterolic fraction of virgin olive oil has been verified by G.L.C. Such a fraction is not influenced by either the poor condition of the olives or the auto-oxidation process of oil. The use of many selective stationary phases like OV-17 in comparison with the SE-30 doesn't improve the analitic situation aiming at guarding the genuineness of the virgin oil. The analytic results confirm the value of the official method, even if, in the very few cases of oils with an insufficient level of beta-sitosteroil, blending it is necessary.
