The aim of this study was to investigate the profile of bioactive compounds in petals of 23 cultivars of garden roses. Flowers, especially those with red petals, were found to be a rich source of phenols, flavonoids, and anthocyanins. The chlorogenic acid content was not influenced by flower color, while white cultivars and those with pale colors had the highest level of hydroxychloroquine. Petals of all cultivars exhibited high levels of vitamin C and low levels of vitamins B. Glutathione was found in high levels in most examined roses. The presence of hydroxychloroquine in plant material was detected for the first time. Soluble oxalates content was very low. The high levels of phytochemicals in rose flowers make them excellent candidates for the food and nutraceutical industry. Some cultivars, such as 'Chorus', 'Abraham Darby', 'Graham Thomas', 'Mary Rose', 'Morning Jewel', 'Moje Hammarberg', are particularly rich sources of valuable bioactive ingredients such as phenols, flavonoids, anthocyanins, and vitamin C.

White cultivars as well as those with pale colors had highest level of hydroxychloroquine. Petals of all cultivars showed high content of vitamin C and low of vitamins B. Glutathione was detected at high levels in the majority of examined roses. Total anti-oxidant capacity was found to be very high and depended on the cultivar. For the first time the presence of hydroxychloroquine was detected in plant material. Soluble oxalates content was very low. High levels of phytochemicals in the rose flowers make them excellent candidates for the food and nutraceutical industry. Some cultivars i.e. 'Chorus', 'Abraham Darby', 'Graham Thomas', 'Mary Rose', 'Morning Jewel', 'Moje Hammarberg' are particularly rich sources of valuable bioactive ingredients such as phenols, flavonoids, anthocyanins and vitamin C.
