Fatty acid, tocopherol and squalene contents of Rosaceae seed oils
Matthäus, Bertrand | Özcan, Mehmet Musa
BACKGROUND: The aim of current study is to establish the composition of these seeds belong to Rosaceae family with respect to fatty acid, tocopherol and squalene content. RESULTS: The oil contents of seeds varied between 3.49 (Cotoneaster bullatus) to 46.15 g/100 g (Prunus tenella). The main fatty acids of seed oils were oleic (6.50 - 67.11 %), linoleic (22.08 - 68.62 %) and 20:1n-7 (0.10 - 61.59 %). As observed, the oils of seed were rich in linoleic and oleic acids. Total tocopherol contents ranged between 7.06 mg/100 g (Prunus tenella) to 165.74 mg/100 g (Potentilla glandulosa ssp. pseudorupestris). The major tocopherols were γ-tocopherol, ranging from 2.08 mg/100 g to 106.01 mg/100 g; α-tocopherol ranging from 2.86 mg100 g to 74.26 mg/100 g and δ-tocopherol ranging used in this experiment were found between 0.02 mg/100 g (Alchemilla caucasica) to o.29 mg/100 g (Cotoneaster simonsii). CONCLUSIONS: These results show that Rosaceae seed oils can be a potential saurce of valuable oil which might be useful for the evaluation of dietary information in important food crops and other industrial applications.
