Abstract
Carotenoids from Anthers and Petals of Lilium tigrinum cv. ‘Red Night’Amongst the 29 carotenoids separated and characterized by modern methods the following are worth mentioning: (9′Z)‐, (9Z)‐, (13′Z)‐ und (13Z)‐capsanthins (20–23), the novel 6‐epikarpoxanthin (= (3S,5R,6S,3′R)‐5,6‐dihydro‐β,β‐carotene‐3,5,6,3′‐tetrol; 25), karpoxanthin (= (3S,5R,6R,3′R)‐5,6‐dihydro‐β,β‐carotene‐3,5,6,3′‐tetrol; 28), and lilixanthin (= (3S,4S,3′S,5′R)‐3,4,3′‐trihydroxy‐β,κ‐carotene‐6′‐one; 26). The main carotenoids from the petals, in comparison with those of the anthers, represent a more advanced metabolic state.
