Rosehip (Rosa canina L.) Oil

Chemical Characterization of Rosa canina L. Rosehip Seed: Application of Raman Spectroscopy and Gas Chromatography

“…The content of oil in rosehip seeds is low, up to 15%. The extraction procedure affects the oil yield, and the modern methods usually provide higher yields compared to Soxhlet extraction [5,22]. In this study, the yield of the seed lipid fraction obtained by the application of ultrasound-assisted extraction (UAE) was 5.6% (0.14 g per 2.5 g of seeds), which is in line with literature data for other extraction methods [5,22].…”

“…Rosehip fruits contain about 30-35% of seeds [4], which are considered as the waste material in the production of marmalade, jam, beverages, jelly, syrup, tea, etc. In recent years, due to their specific fatty acid composition, rosehip seeds have been used in the cosmetic and pharmaceutical industries [5]. They are a good source of linoleic, linolenic, palmitic and stearic acid.…”

Stabilization of rose hip oil with pomegranate peel extract during accelerated storage

“…6,7 Furthermore, it was noted that topical application of rose hip oil together with oral application of poly-vitamin preparation of fat-soluble vitamins could exhibit a synergistic effect. 4 Diet supplemented with 15 % rose hip oil caused a hypolipidemic effect in rat's plasma as a consequence of high content of PUFA. 8 Therefore, rose hip oil can be beneficial in various products such as cosmetics, pharmaceutics, and nutraceuticals.…”

“…3 The quantity of oil in the rose hip seeds is between 5 and 18 % and it is known as a rich source of polyun-saturated fatty acids (PUFA), as well as tocopherols, carotenoids, sterols, phospholipids, and phenolic compounds. 1,4,5 It was reported previously that rose hip seed oil could be used for the treatment of eczema, skin ulcers, neurodermitis, cheilitis, skin scars, as well as for moisturizing and prevention of skin ageing. 6,7 Furthermore, it was noted that topical application of rose hip oil together with oral application of poly-vitamin preparation of fat-soluble vitamins could exhibit a synergistic effect.…”

Extraction of Oil from Rosehip Seed: Kinetics, Thermodynamics, and Optimization

“…It is collected mainly for its fruit (rosehip), which is a source of vitamin C, antioxidants, tocopherols, essential fatty acids, carotenoids, carbohydrates, proteins, and trace elements [1,2]. The fruit contains about 70 % of the pericarp and 30 % of the seed [3]. The rosehip seed (RS) is a byproduct of the fruit processing and is considered a waste that is burned or used for animal feeding [4].…”
