NOVELTY - Method for extraction of coenzyme Q10, involves mixing Rhodotorula rubra, Rhodobacter sphaeroides and Paracoccus denitrificans, inoculating the bacteria into fermentation medium, shaking medium, centrifuging, drying the washed bacterial cells, mixing crushed bacterial cells with n-hexyl dioxane, stirring, extracting, filtering, adding alcohol solution, shaking, concentrating, subjecting the concentrate to column chromatography, vacuum-filtering, drying, adding e.g. cypress, stirring, performing distillation, drying, and crushing dried product.    USE - The method is useful for extraction of coenzyme Q10 (claimed).    ADVANTAGE - The method is simple to operate, cost-effective, environmentally-friendly, low in requirements on instruments and device.    DETAILED DESCRIPTION - Method for extraction of coenzyme Q10, involves (a) mixing Rhodotorula rubra (ATCC74283), Rhodobacter sphaeroides (ATCC17025) and Paracoccus denitrificans (ATCC19367) in a volume ratio of 1:1:2 to obtain mixed bacteria, inoculating the bacteria into fermentation medium, and performing shaking process at 29 degrees C and 100 revolutions per minute (rpm) for 30 hours to obtain fermentation broth, (b) centrifuging the fermentation broth at 4000-5000 rpm to separate supernatant and bacterial cells, washing the bacterial cells, drying the washed bacterial cells at 60 degrees C, mixing crushed bacterial cells with n-hexyl dioxane in a mass ratio of 1-2:2-3, stirring the mixture, extracting the mixture at 55-60 degrees C for 1.5-2 hours, and filtering the extract using microfiltration membrane, (c) mixing the extract with alkaline alcohol solution in a volume ratio of 1-2:2-3, shaking the mixture for 5 minutes, maintaining the mixture at 55-60 degrees C and 0.04-0.06 MPa, and concentrating the mixture by rotary evaporation, (d) subjecting the concentrate into silica gel column chromatography, further concentrating the mixture at 55-60 degrees C and 0.04-0.06 MPa, dissolving the concentrate in absolute ethanol, refrigerating the mixture at 4 degrees C in overnight, vacuum-filtering the mixture and drying the mixture, and (e) adding complex, cypress, distillers grains, rice straw and wheat bran flour in a ratio of 100:3:2:1:1 to the dried mixture, stirring the mixture at 2000 rpm for 10 minutes, steaming the mixture, performing distillation of the mixture for 30 minutes, drying the mixture, and crushing dried product.
