Abstract

Sterol analysis is a key parameter for assessing the authenticity and quality of olive oil, as defined by official methods. Nevertheless, these protocols are labor-intensive and require multiple preparation steps, including sample fractionation and derivatization. In the present work, a simplified analytical methodology is proposed for the determination of free sterols and triterpenic alcohols, el…
