Seed oils recovered from Rosaceae species such as dessert and cider apples (Malus domestica Borkh.), quince (Cydonia oblonga Mill.), and rose hip (Rosa canina L.) were analyzed for their tocopherol and carotenoid contents using HPLC-DAD-MS n following saponification. Qualitative and quantitative tocopherol and carotenoid compositions significantly differed, not only among the different genera but also among cultivars of one species. In particular, seed oils of cider apples were shown to contain higher amounts of both antioxidant classes than that of dessert apples. Total contents of tocopherols of the investigated Rosaceous seed oils ranged from 597.7 to 1099.9 mg/kg oil, while total carotenoid contents varied between 0.48 and 39.15 mg/kg oil. Thus, these seed oils were found to contain appreciable amounts of lipohilic antioxidants having health beneficial potential. The results of the present study contribute to a more economical and exhaustive exploitation of seed byproducts arising from the processing of these Rosaceous fruits.
