### Carotenoids Composition  
According to the literature, rosehips have a high level of carotenoids compared to other fruits [23]. Our study showed that in the flesh of organic rosehips lutein and zeaxanthin were composed from 12.89-20.53%, \(\beta\)-carotene 45.56-70.34%, \(\alpha\)-carotene 6.97-13.51%, and total lycopene 9.29-24.68% of the total amount of carotenoids. Carotene corresponded from 54.79% to 77.31% of total carotenoids in rosehips flesh (Table 1). It is generally known that rosehips are rich in bioactive compounds, such as carotenoids. However, the differences in content of these compounds depend on many factors: genetic variation, maturity of the fruit, degree of ripening, growing, climate, and storage conditions, as well as, extraction and analytical method [24]. The total content of lycopene (_cis_-lycopene + _trans_-lycopene) in organic rosehip flesh ranged from 1.18 mg g\({}^{-1}\) to 5.62 mg g\({}^{-1}\) DW, and the significantly highest amount was identified in RV flesh (Table 1). The isomer pattern, with its high relative content of _cis_-isomers of lycopene, was unexpected. Rosehips flesh showed a ratio of _trans_-lycopene to _cis_-lycopene isomers ranging from 74:26 to 79:21 (Table 1). Other authors [5, 23] show much lower amounts of lutein and zeaxanthin, at concentrations of 2.21 mg 100 g\({}^{-1}\) and 2.00 mg 100 g\({}^{-1}\), respectively. Our results showed that the lutein and zeaxanthin amount was significantly higher, namely, 6.38 mg 100 g\({}^{-1}\) DW in RV species flesh (Table 1). The orange pigment beta caroten is the most common of various carotenoids in food products, either as a major or minor ingredient [25]. The significant differences in the amount of \(\beta\)-carotene were investigated for all species of organic rosehips. According to literature the carrot (_Daucus carrota_ L.) has some of the greatest levels of beta caroten, and the concentrations of this carotenoid in carrot may fluctuate from 3.2 mg 100 g\({}^{-1}\) to 6.1 mg 100 g\({}^{-1}\) fresh weight (FW) [26]. However, rosehip flesh can have higher \(\beta\)-carotene concentrations than that of carrot, and the values range from 3.95 mg 100 g\({}^{-1}\) to 31.40 mg 100 g\({}^{-1}\) DW (Table 1). Our data showed that the amount of \(\beta\)-carotene in RC species was eight times lower, while the amount detected in the flesh of RV species was significantly higher (31.40 mg 100 g\({}^{-1}\) DW). The quantitative and qualitative composition of carotenoids in organic rose fruit flesh and seeds varied dependently. \(\beta\)-carotene, \(\alpha\)-carotene, lutein, zeaxanthin and _cis_- and _trans_-lycopene were detected in flesh, while \(\beta\)-carotene was not detected in seeds. In addition, rosehip seeds revealed a lower carotenoid content than did rosehip flesh, and \(\alpha\)-carotene and lutein were obtained only in the RRR and RV species (0.20 and 0.31, 0.04 and 0.40 mg 100 g\({}^{-1}\) DW, respectively) (Table 1). [PERSON] et al. [1] also confirmed that carotenoid contents varied between rosehips species. These authors found that _R. rugosa_ hips contained (all-E)-violaxanthin and (5\({}^{\prime}\)Z)-rubixanthin (gazaniaaxanthin) in contrast to _R. canina_ hips. Moreover, _R. rugosa_ also contained a higher content of (all-E)-\(\beta\)-cryptoxanthin (1.2 mg 100 g\({}^{-1}\)) compared with _R. canina_ hips (0.1 mg 100 g\({}^{-1}\)). However, _R. canina_ hips contained a higher content of (all-E)-\(\alpha\)-cryptoxanthin (1.1 mg 100 g\({}^{-1}\)), compared to _R._ rugosa hips (0.01 mg 100 g\({}^{-1}\)). A study conducted on five _Rosa_ species (_R. canina, R. moschata, R. damascena, R. webbiana_, and _R. hemispheraica_) reported concentrations of total carotenoid 3.03 mg 100 g\({}^{-1}\) (_R. moschata_) and 20.21 mg g\({}^{-1}\) fresh weight (FW) (_R. damascena_).
