Reinvestigation of the Carotenoids from Rosa foetida, structures of 12 Novel Carotenoids; Stereoisomeric Luteoxanthins, Auroxanthins, Latoxanthins and LatochromesFrom petals of the yellow Rosa foetida HERRM., more than 35 individual carotenoids were isolated and identified. Thereof, 87% belong to the expoxycarotenes. Structures were assigned for the first time to 4 auroxanthins ((8R,8′S), 6; (8S,8′S), 7; (8R,8′R), 8; (9Z,8R,8′R), 12), to 4 luteoxanthins ((8′R), 4; (8′S), 5; (9Z,8′R), 9; (9Z,8′S) 10(e)) and to novel latoxanthins and latochromes, very polar carotenoids having (3S,5R,6R)-trihydroxy β-end groups (latoxanthins 13 and 16, latochromes 14 and 15).
