Notes: Carotenoids in petals of Rosa foetidaThe petals of Rosa foetida, HERRM., a species of prime importance in the history of breeding true yellow garden roses, have been analysed for carotenoids for the first time. The following components were identified: β-carotene (1, 4,5%), lutein (2, 8%), zeaxanthin (3, 17,4%), auroxanthin (4, 30,8%), luteoxanthin (5, 21,9%), violaxanthin (6, 9,2%) and neochrome (7, 4,1%). Not identified carotenoids (4,1%) contained probably mutatoxanthin, antheraxanthin and apocarotenals. Thus the brillant yellow colour of R. foetida flowers is due mainly to carotenoid epoxides.
