Rosehips flesh is a source of the vitamins, minerals, carotenoids such as lycopene, zeaxanthin, lutein, α, β -carotene and other biological active compounds. A two-factor field experiment with two rosehip species R. Rugosa and R. Canina was conducted in 2017–2018 on an organic farm in Pakruojis district Lithuania. The fruits were harvested five times in season and the carotenoids amount were compared at different stages of rosehip development. The aim of this research was to determine the effect of ripening stage on some carotenoids composition of two different rosehip flesh species R. Rugosa and R. Canina. Content of lutein, zeaxantin, α, β-carotenes and cis-lycopene, trans-lycopene in the fruits of rosehip were determined by the method described by Hallmann (2012) with some modifications. The results revealed very large variations in amount of carotenoids in the rosehips, both in terms of total amount and in composition of specific carotenoid compounds. β-carotene was the predominant carotenoid in rosehip fruit. The flesh of the R. canina and R. rugosa had the highest amount of β-carotene at ripening stage V (14.10 and 18.55 mg 100 g-1 DW, respectively), with significant differences between them. The R. canina flesh had significantly highest amounts of lutein at ripening stage V (9.19 mg 100 g-1 DW). Significantly highest zeaxanthin concentrations were established at ripening stages III, IV and V of R. canina, compared with R. rugosa. The highest amounts of the lycopene were found in the flesh of R. canina at ripening stage V
