Abstract
In the study, the macro and micro elements and fatty acid contents in rose seeds, which are generally evaluated in the waste category, were determined. Among the plants belonging to these taxa, only the registered varieties belonging to four taxa were used, while the others were genotypes. The plant materials of the study include rosehip (R. canina L.), Yildiz variety of rosehip (R. canina L. cv ‘Yildiz’), Syrup rose (R. heckeliana Tratt. subsp. vanheurckiana), Austrian briar (R. foetida Herrm.), lax rootstock [R. caesia Sm. (Syn: R. laxa Retz.)], wild rose [R. montana subsp. woronovii Chaix subsp. woronovii (Lonacz) Ö. Nilsson L.], hybrid landscape roses (R. x hybrida) and Hosap rose [R. pisiformis (Christ) D.] taxa. It was determined that the contents of nitrogen, potassium, phosphorus, magnesium and calcium of the macro elements examined in the seed samples differed statistically from each other. The seeds of different Rosa L. species examined within the scope of the research can be considered as one of the fruit oil sources with its 3.71-10.01% oil content. The fatty acid contents were determined as follows: linoleic acid (ω6) contents in the taxa ranged from 41.63 to 50.11% with an average of 44.88%; oleic acid (ω9) ranged from 20.80 to 30.27% with an average of 24.95%; linolenic acid (ω3) varied between 14.00-28.51% with an average of 19.20%; arachidic acid ranged from 0.75-1.63% and the average was 1.97%; eicosenoic acid ranged between 0.13-0.65% and averaged 0.33%; palmitoleic acid contents ranged from 0.08-0.60; behenic acid varied between 0.08-0.19% with 0.11% average. It was observed that the (ω3/ω6 ratio of the hybrid rose, which is especially used as a landscape rose and whose fruits are not evaluated, had an average value. R. canina ‘Yildiz’ cultivar showed a high (ω3/ω6 ratio, which is important in health terms. The high oleic acid contents found in these taxa are important results.
期刊介绍:
Grasas y Aceites is a peer-reviewed journal devoted to the publication of original articles concerning the broad field of lipids, especially edible fats and oils from different origins, including non acyl lipids from microbial origin relevant to the food industry. It publishes full research articles, research notes, reviews as well as information on references, patents, and books.
Grasas y Aceites publishes original articles on basic or practical research, as well as review articles on lipid related topics in food science and technology, biology, (bio)chemistry, medical science, nutrition, (bio)technology, processing and engineering. Topics at the interface of basic research and applications are encouraged. Manuscripts related to by-products from the oil industry and the handling and treatment of the wastewaters are also welcomed.
Topics of special interest to Grasas y Aceites are:
-Lipid analysis, including sensory analysis
-Oleochemistry, including lipase modified lipids
-Biochemistry and molecular biology of lipids, including genetically modified oil crops and micro-organisms
-Lipids in health and disease, including functional foods and clinical studies
-Technical aspects of oil extraction and refining
-Processing and storage of oleaginous fruit, especially olive pickling
