Method for extracting coenzyme Q10 from fermentation mycelia

The invention relates to a method for extracting a coenzyme Q10 from fermentation mycelia. The method comprises the following steps: filtrating and drying coenzyme Q10 fermented liquid so as to obtain mycelia, granulating the mycelia into 10-120-mesh granules, putting the granules into an extracting tank, carrying out subcritical extraction on the bacteria by taking subcritical fluid as an extraction solvent, then filtering so as to obtain extraction liquid and fungi residues, feeding the extraction liquid into an evaporation system, desolventizing the extraction liquid under a reduced pressure condition so as to obtain an coenzyme Q10 extract, and carrying out subsequent purification treatment on the coenzyme Q10 extract so as to obtain an coenzyme Q10 finished product. Because the subcritical fluid is adopted for extracting coenzymes Q10, the method disclosed by the invention is high in extraction yield, low in solvent loss, good in quality of products, low in operation cost, relatively short in production cycle, and large in relative yield, therefore, the method is a high-efficiency, low-consumption, environment-friendly and clean production technology of coenzymes Q10.
