Abstract

The invention discloses a method of separating and extracting coenzyme Q10 from microbial fermentation broth. The method includes filtering the microbial fermentation broth, and drying to obtain bacterial powder; using a micronization technique to crush the bacterial powder into coenzyme Q10 micropowder 2-35 mu m in particle size; extracting, performing solid-liquid separation, carrying out chromatography, and crystallizing to obtain finished coenzyme Q10. The method herein has high yield; product quality is good; the process is simple; extraction time is short; separation and extraction efficiency is high; the cost is low; the method is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of extraction of coenzyme Q10, in particular to a method for separating and extracting coenzyme Q10 from microbial fermentation broth. Background technique [0002] Coenzyme Q10 (Coenzyme Q10, abbreviated as CoQ10), also known as ubiquinone, is a vitamin-like substance widely present in animals, plants and microorganisms. Coenzyme Q10 is a cell metabolism activator and antioxidant synthesized spontaneously by organisms. It can act on certain enzymes to cause changes in their three-dimensional structures, thereby affecting their physiological activities. Past research and clinical trials have proved that coenzyme Q10 can increase the body's immunity, prevent cardiovascular and cerebrovascular sclerosis, and help improve hypertension, congestive heart failure, nervous system diseases, and tumor treatment. At present, coenzyme Q10, as a precious natural product, is widely used in the production of biochemical drugs, hea...
