FIELD: biotechnologies.
SUBSTANCE: invention may be used to extract carotenoids, in particular, deinoxanthine, which is used to develop new antioxidant and radioprotector preparations to increase adaptation capabilities of humans and aminals, prevention and treatment of diseases. The method provides for extraction of carotenoids from the bacterial mass Deinococcus radiodurans by the mixture acetone : ethanol (at the 1:1 ratio). Separation of carotenoids with extraction of deinoxanthine on preparative columns of a liquid low-pressure chromatograph, where the sorbent is hydroxyapatite, and the eluent - ethanol.
EFFECT: invention makes it possible to increase quantity and quality of extracted deinoxanthine.
