The crystal powder of the ubiquinone compressing forming by formation linear load of 0.6 - 2.5 tons, /cm pulverizing the compressed piece which is obtained with the process 1 which, obtains the compressed piece and process 1 it possesses with the process 2 which obtains the powder body, it is the powder for the formulation of the ubiquinone which can by the production method, and the said production method of the powder for the formulation of the ubiquinone. Bulk density is high with the said production method, without using additive such as shape medicine and binder, repose angle is small, you handle and the medicine of the ubiquinone which is superior in characteristic and flowability and offering the powder for the formulation of the health food become possible.ユビキノン類の結晶粉末を0.6~2.5トン/cmの成形線圧で圧縮成形して圧縮片を得る工程1と、工程1で得られた圧縮片を粉砕して粉末体を得る工程2とを有する、ユビキノン類の製剤用粉末の製造方法、および該製造方法によって得られるユビキノン類の製剤用粉末である。該製造方法によって、賦形剤や結合剤などの添加剤を用いることなく、嵩密度が高く、安息角の小さい、取り扱い性及び流動性に優れたユビキノン類の医薬及び健康食品用の製剤用粉末を提供することが可能となる。
