Rose hip (Rosa canina L.) oil obtained from waste hip seeds by different extraction methods

Rosa × alba: source of essential minerals and volatile oils

“…Another report from the same country showed that the fruit of different Rosa species contains P (4860-5360 ppm), K (5467-7700 ppm), Ca (1220-2867 ppm), Mg (990-1254 ppm), Fe (18-72 ppm), Cu (9-27 ppm), Mn (6-56 ppm) and Zn (18-42ppm) 3 . The mineral content of rose hip has been also reported in Hungarian specimen 8 . These authors determined that the seeds contain Al (12 ppm), B (7.54 ppm), Ca (7948 ppm), Cr (0.211 ppm), Cu (5.69 ppm), Fe (20.15 ppm), K (3786 ppm), Mg (1193 ppm), Mn (22.54 ppm), Na (12.28 ppm), P (1781 ppm), S (866.2 ppm) and Zn (10.84 ppm).…”

“…Nevertheless, few reports regarding the mineral composition of some Rosa species have been published 3,7,8 . At this point, Demir and Özcan 7 studied the chemical composition of R. canina fruits collected in two distinct locations from Turkey and found that the dry matter content varied from 20.5 to 23.47%, total fat (1.2-1.6%) and total ash ranged from 6.48 to 7.35%.…”

“…Six years later, report from the same country revealed that the dry matter content in the fruits of six Rosa species ranged from 33.85 to 40.35% 3 . By using different extraction methods, Szentmihályi et al 8 reported that the total fat in R. canina seeds from Hungary ranged from 3.25 to 6.68%.…”

“…The functional properties of some Rosa species were attributable to a wide array of bioactive ingredients such as minerals, fatty acids, volatile oils, ascorbic acid, phenols, flavonoids, tannins and sugar [7][8][9][10][11] . Despite the substantial data on the phytochemistry of some Rosa species namely R. canina, there are a dearth of information about the chemical constituents of Rosa x alba.…”

Healing incisional surgical wounds using Rose Hip oil in rats

“…We must consider that human skin differs from rat and the important difference is that human skin cures preferentially by re-epithelialization, whereas the skin of the rat heal mainly by contraction of the wound [27]. We also recognize the limitations for translational relevance of our experimental study.…”
