Abstract
The present invention provides a method of producing reduced coenzyme Qcrystals suitable for commercial scale production thereof. According to a method of the present invention of producing a reduced coenzyme Qcrystal which comprises a crystallization of reduced coenzyme Qin a solution of alcohols and/or ketones, reduced coenzyme Qcrystal excellent in slurry properties and crystalline properties maybe obtained. Moreover, an isolation process including a crystal separation or the whole process including the isolation process maybe minimized and simplified. Thus, highly pure reduced coenzyme Qmay be obtained in a high yield.
