Quantification of Sterol Contents in Almond (PrunusamygdalusL.) Oils

In this study, the sterol contents of almond kernel oils collected from naturally growing almond trees in Mersin province were determined. Generally, the sterol contents of almond oil samples varied depending on almond types. The major sterols in almond oils wereß-sitosterol, ۵-avenasterol and campesterol, followed by ۵,۲۴-stigmastadienol, stigmasterol, sitostanol, and cholesterol. While β-sitosterol contents of almond oils varied between ۱۹۸۶ mg/kg (T۲۶) and ۳۹۰۸ mg/kg (T۱۶), ۵-avenasterol contents of almond oils samples were in the range between ۲۱۵.۹ mg/kg (T۳۱) and ۵۸۱.۷ mg/kg (T۱۶). In addition, campesterol contents of oils were found from ۷۵.۸ mg/kg (T۳۱) to ۱۷۲.۳ mg/kg (T۱۶). Interestingly, all sterol contents (except cholesterol, brassicasterol and ۷-campesterol) of T۱۶ almond oil were found higher than those of the other almond types. The current study showed that almond kernels of the investigated almond types from Turkey are potential sources of valuable oil which might be used as edible oil or industrial applications.
