The average carotenoid content (lutein and zeaxanthin) was ca. 102 mg kg(-1) of total extracted lipids. Lutein (ca. 97 mg kg(-1) of total extracted lipids) was usually more abundant than zeaxanthin (ca. 5 mg kg(-1) of total extracted lipids). The mean total tocopherol content was ca. 704 mg kg(-1) of total extracted lipids. The main isomer was alpha-tocopherol, with more than 75 % of total tocopherols (ca. 528 mg kg(-1) of total extracted lipids), followed by gamma-tocopherol (ca. 168 mg kg(-1) of total extracted lipids) and delta-tocopherol (ca. 86 mg kg(-1) of total lipids). High levels of phytosterols (ca. 7.8 g kg(-1) of total extracted lipids) were detected, among which beta-sitosterol was the most abundant (47 %). All these results highlight the richness of carotenoids, tocopherols and sterols in A. cyanophylla seed oil, and imply that this species might constitute a potential resource for the development of functional foods.
