Nutrient composition of rose (Rosa canina L.) seed and oils.

Rose seeds were evaluated for weight of 100 seeds, moisture, crude protein, ash, crude oil, energy, and mineral content. Also, fatty acid composition was determined in the seed oils. The weight of 100 seeds, moisture, crude oil, energy, and iron (Fe) content of Ermenek rose seeds were found to be higher than those of other regions. The major fatty acids identified by gas chromatography of rose seed oils growing wild in the Hadim, Taskent, and Ermenek regions in Turkey were, respectively, as follows: palmitic (3.17%, 1.71%, and 2.14%), stearic (2.47%, 2.14%, and 1.69%), oleic (16.73%, 18.42%, and 14.71%), linoleic (54.41%, 51.71%, and 48,64%), linolenic (17.14%, 16.42%, and 18.41%), and arachidic (2.11%, 1.87%, and 2.61%). The seeds were rich in oil and minerals. The oil may be valuable for food and other uses because of its high unsaturated content.
