6‐Epikarpoxanthin ((all‐ E ,3 S ,5 R ,6 S ,3′ R )‐5,‐6‐dihydro‐β,β‐carotene‐3,5,6,3′‐tetrol, 5 ), 5,6‐diepikarpoxanthin ((all‐ E ,3 S ,5 S ,6 S ,3′ R )‐5,6‐β,β‐carotene‐3,5,6,3′‐tetrol, 13 ), 5,6‐diepilatoxanthin ((all‐ E ,3 S ,5 S ,6 S ,3′ S 5′ R ,6′ S )‐5,6′‐epoxy‐5,6,5′,6′‐tetrahydro‐β,β‐carotene‐3,5,6,3′‐tetrol, 14 ), and 5,6‐diepicapsokarpoxanthin ((all‐ E ,3 S ,5 S ,6 S ,3′ S ,5′ R )‐5,6‐dihydro‐3,5,6,3′‐tetrahydroxy‐β,κ‐caroten‐6′‐one, 15 ) were isolated from red spice paprika ( Capsicum annuum var. longum ) and characterized by their UV/VIS, CD, 1 H‐ and 13 C‐NMR, and mass spectra. Our investigations demonstrate that the configuration of the 3,5,6‐trihydroxy‐5,6‐dihydro‐β‐end group may differ depending on the biological source.
