Sažetak
Roses (genus Rosa L.) leaves and petals are used in food and cosmetic industry due to the bioactive specialized metabolites they contain, however there are no comparative data on the qualitative and quantitative content of those metabolites in the cultivars of different colors. 13. HBK 213 13th CBC Photosynthetic pigments, flavonoids and phenolic acids play a key role in photosynthesis, metabolism and plant protection against biotic and abiotic stress, and are main bioactive components of roses. Therefore, we screened for these components in leaves and petals of three differently coloured cultivars collected in the Botanical Garden in Zagreb with the aim of comparing their bioactive potential. The results revealed that more bioactive components were present in leaves than in petals of roses. Roses (both leaves and petals) of different colours showed a specialisation in bioactive components representation. The results showed that in cultivars of different colours a trade-off between amount of photosynthetic pigments, flavonoids and phenolic acids, especially in leaves, exists.
