Background. One of the urgent problems of modern pharmaceutical science is to provide preventive and medical products on the basis of photosynthetic pigments of the plant cell. Methods. To assess the biological potential of coniferous species in terms of the source of carotenoids the annual dynamics of accumulation of these pigments in the two-year needles of eight species of naturalized and Far Eastern plants were studied. Results. It was established that the maximum number of yellow pigments in the Far East recorded species – a juniper and a solid yew, the minimum – in the naturalized juniper hemispherical.Far Eastern plants accumulated 1.3 times more carotenoids in a year than types of another regions. Conclusions. Plants with the highest content of carotenoids were identified: the Far Eastern species – a juniper solid (0.31 mg/g) and yew (0.30 mg/g), exotic species – yew form “low” (0.29 mg/g) and cypress Lawson (0.28 mg/g). The findings expand the idea of the synthesis of carotenoids coniferous species of plants and the possibility of using needles as an additional source of multivitamins, food additives and dyes.
