Abstract: Rosehips are generally known to contain high levels of health-promoting compounds such as carotenoids and polyphenols. Differences in content may exist due to genetic variation, degree of ripening, variations within and between years, climate, growing and storage conditions, and analytical method. The aim of this study was to determine bioactive compounds of five different rosehip species (R. rugosa, R. rugosa 'Rubra', R. rugosa 'Alba', R. canina, R villosa), growing in Pakruojis area in Lithuania. Content of carotenoids in the flesh of rosehips species were determined by the method described by Helsper et al., as well phenolic compounds – by Hertog et al., with some modifications. The results showed large variations of the content of carotenoid compounds in all investigated rosehips species. It was found that R. villosa were significantly rich in β-carotene, lutein and lycopene (respectively 31.40, 6.06 and 5.63 mg 100 g-1 DW). The total phenolic acid content varied from 89.23 to 121.81 mg 100 g-1 DW and total flavonoids – 34.23–41.59 mg 100 g-1 DW. The results demonstrated that the significantly highest concentrations of polyphenols were identified in the R. canina species (157.42 mg 100 g-1 DW). The rosehip flesh of species R. villosa accumulated by on average 55.5% significantly higher contents of lutein, 65.8% mg 100 g-1 – of lycopene and 66.1% – β-carotene, compared with the other species
