Evaluation of Fatty Acid Composition and Stability of Rose Hip Oil

Rosa canina is one of the Rosa species which grows wildly in various regions of Iran. The fruit of this plant "Rose hip" is well-known for its efficacy in strengthening the bodyʹs defense against infection and particularly the common cold. Furthermore it has preventive and remedial properties in cardiovascular and renal diseases. In this study the oil extracted from Rose hip seed collected from Ardabil province was analysed for fatty acid composition by gas chromatography. The results showed high quantities of linoleic and linolenic acids, 44% and 22% respectively. Rancimat method indicated that the oil has a low resistance to oxidation. Chemical properties of the seeds concerning moisture, ash, fat, protein and crude fiber indicated a high percentage of fiber and acceptable concentration of protein in the residue of defatted seed which might be used as animal feed.
