Multi-elemental Analysis, Pattern Recognition Techniques of Wild and Cultivated Rosehips from Serbia, and Nutritional Aspect

Rapid characterization of hypanthium and seed in wild and cultivated rosehip: application of Raman microscopy combined with multivariate analysis

“…Having in mind that the rosehip fruit is a good source of carotenoids [12] and unsaturated fatty acids such as linolenic, linoleic and oleic acid [41], the band 1446 cm −1 could be associated with the lipid class. As rosehip flesh is rich in various carbohydrates [10,12], the bands observed below 1000 cm −1 may probably be related to this class of compounds. Synytsya et al [42] assigned the bands at 953, 365 and 751 cm −1 to polygalacturonic ( pectic) acid and pectin, respectively.…”

“…The average Raman spectra of the rosehip seed samples of the so-called fingerprint region (200-1800 cm −1 ) are presented in figure 3, while characteristic bands and the related assignments are reported in the electronic supplementary material, table S1. The obtained spectra include bands that may be associated with the most important compounds found in rosehip seeds such as fatty acids [14,25,43], proteins [14,41], phenolic compounds and carbohydrates [10,14,25].…”

“…Phenolic compounds are constituents of rosehip seed that contribute to its antioxidant properties [10,14]. The highest intensity band (1596 cm −1 ) in the average Raman spectra of seed samples (1S-10S), is correlated to ν(C = C), the structural feature of phenolic compounds [25,44,45].…”

“…Rosehips have been found to contain higher amounts of various bioactive compounds than several other fruits and berries [7]. The fruits of different rose species are a rich source of carotenoids, proteins, sugars, organic acids, phenolic compounds, essential elements and vitamins (B-group, C and E) [5,6,[8][9][10][11][12]. The health benefits of rosehips are mainly linked to the presence of bioactive compounds, such as a high content of carotenoids, mainly represented by lycopene and β-carotene, and only traces of lutein, zeaxanthin and rubixanthin [13], in addition to the remarkable content of ascorbic acid, total polyphenols, tocopherol, pectin and other metabolites.…”

Fatty acid composition of rosehip seed oil

“…The rosehip fruit is widely used in the food industry. Also, its potential as a component of functional food is notable due to a significant content of numerous bioactive compounds and essential elements in this pseudo fruit (Ercisli et al, 2007;Ilyasoğlu, 2014;Popović-Djordjević et al, 2020). Rosehip fruits contain 30-35 % of seeds, and the content of oil in seeds may vary from 3-7 % depending on applied extraction method (Zlatanov, 1999;Dabrowska et al, 2019).…”
