“…Summary of the literature data on the oil extraction yield and fatty acid profile in R. canina seed oil from raw materials from Poland, Hungary, Germany, Bulgaria, and Turkey is given in Table . In almost all cases seed oil was obtained by extraction in Soxhlet apparatus, however, different solvents were used: hexane, petroleum ether, and diethyl ether . The oil content (4.07–12.90%) varied strongly depending on the variety of the raw material but also depending on its origin .…”

“…Research taking into account other rose species are rare and mainly focused on the determination of oil content and fatty acid composition. They comprise numerous wild growing rose species from Turkey, Poland, India, and Tunisia . These oils are rich in polyunsaturated fatty acids, mainly linoleic (omega‐6) and α‐linolenic (omega‐3), as well as carotenoids and vitamin A which makes them valuable raw material for food and cosmetic industry.…”

Recently, there has been growing interest in the use of uncommon plant oils in the food and cosmetic industries. Oils obtained from Rosa canina L. and R. rubiginosa L. seeds are widespread on the market and recommended for pharmaceutical, cosmetic, and nutritional purposes. Both these oils are quite well investigated. However, Rosa L. genus includes numerous other species bearing fruits (hips) with seeds rich in active compounds. These rose species may also be a source of oil valuable for purposes above mentioned. Thus recent literature relating to rosehip seed oils, its extraction methods and composition are summarized to provide an overview of the published data on this subject. The goal of this article is to deliver necessary background with references for an up‐to‐date perspective of different rose species' seed oils, to review methods for their isolation, and thereby to compare oil extraction yield and composition. Practical Applications: This review underscores the importance of rose hip seed oil as a product for healthier foods and other purposes. Uncommon plant oils have recently gained popularity in the food and cosmetic industries. Oils obtained from Rosa canina and R. rubiginosa seeds are recommended for pharmaceutical, cosmetic, and nutritional purposes. Moreover, Rosa L. genus includes numerous other species' seeds rich in active compounds. Thus recent literature relating to rose hip seed oils, its extraction methods, and composition are summarized to provide an overview of the published data on this subject.

“…Dry seeds from blackcurrant, raspberry, or strawberry may contain up to 25% of fat and 20% of proteins, and in this way, they can be an interesting material to receive oily extracts rich in unsaturated and polyunsaturated fatty acids (Nawirska 2007;Rój et al 2009;Nowak 2005;Dobrzyńska et al 2014). …”

Fatty Acids Analysis Using Gas Chromatography-Mass Spectrometer Detector (GC/MSD) - Method Validation Based on Berry Seed Extract Samples

Oily seed extracts were used as research samples in Analytical Laboratory of Raw Materials and Plant Products. Supercritical carbon dioxide extraction on an industrial scale was used to prepare extracts from raw plant materials, usually berry seeds: blackcurrant, raspberry, strawberry, and chokeberry. Gas chromatography analysis was performed on Agilent equipment with single quadrupole mass spectrometer detector and split/splitless injector. Fatty acids (FAs) were determined using indirect method, where they were converted to c o r r e s p o n d i n g m e t h y l e s t e r s ( FA M E s ) d u r i n g trimethylsulfonium hydroxide solution reaction. Comparing the mass spectrum and retention time peak, more than 30 compounds in different oily extracts were qualitatively identified. Quantification of individual fatty acids was based on two different methods. Firstly, it was based on the received peak area, and the results were normalized without correction factor. Secondly, the quantification was based on external calibration curve, for 34 identified fatty acids. The method was validated, and the results, e.g., linearity, precision, limit of detection (LOD), and limit of quantification (LOQ), were presented.

This study was conducted to determine the change of fatty acids ratios of some rose hip species seeds in different harvest times. Seeds of five genotypes belonging to rose hip species (Rosa sp.) were used in the study. The fruits of species were harvested in six different ripening times and analyzed. Total oil analysis was performed for the fifth harvest only, which was determined as the optimal harvest time. As a result; total oil ratio of rose hip seeds varied as 5.22 and 6.62 g/100g respectively for accessions of Rosa dumalis (MR-12 and MR-15), 6.37 g/100g for R. canina (MR-26), 5.00 g/100g for R. dumalis ssp. boissieri (MR-46) and 5.29 g/100g for R. villosa (MR-84). Eleven fatty acids were determined in rose hip seeds. Among these fatty acids linoleic, oleic, linolenic, palmitic and stearic acids respectively had high ratio. Saturated fatty acids ratio (SFAs) was the highest in R. canina (MR-26) and the lowest in R. dumalis (MR-12); monounsaturated fatty acids ratio (MUFAs) was the highest in R. dumalis (MR-12) and the lowest in R. dumalis ssp. boissieri (MR-46); polyunsaturated fatty acids ratio (PUFAs) was the highest in R. dumalis ssp. boissieri (MR-46) and the lowest in R. dumalis . Mono and polyunsaturated fatty acid contents obtained in this study was high; the change of fatty acid profile in the studied species in relation to harvest time was significant for some species and insignificant for others. A conclusion was reached that it is important to pay attention to qualitative and quantitative properties of seeds when conducting studies about rose hip improvement.
