Abstract

The main pigments of Rhizobium lupini were 2,3,2′,3′‐di‐trans‐tetrahydroxy‐β,β‐caroten‐4‐one and 2,3,2′,3′‐di‐trans‐tetrahydroxy‐β,β‐carotene. As minor components 7,8,7′,8′‐tetrahydro‐ψ, ψ‐carotene (ζ‐carotene), β, β‐carotene (β‐carotene), and tentatively, a 2,3,2′(or 3′)‐trihydroxy‐β, β‐caroten‐4‐one and a 2,3,2′(or 3′)‐trihydroxy‐β, β‐carotene were identified.

## Abstract The structures of the main carotenoid pigments from the mutant 1‐207 of __Rhizobium lupini__ were elucidated by spectroscopic techniques (UV./VIS., CD., 270 MHz ^1^H‐NMR., and MS.). Ten carotenoids were identified, namely β,β‐carotene (**1**), β,β‐caroten‐4‐one (echinenone, **2**), β,β‐
