Abstract
The invention relates to a process for preparing high-density quercetin of improved flowability comprising roller compaction of quercetin, wherein both the obtained high-density quercetin and the quercetin starting material have a purity of at least 95%. The invention also relates to the high-density quercetin obtainable with such process, to the use of high-density quercetin for preparing pharmaceutical dosage forms, to pharmaceutical dosage forms comprising high-density quercetin as active ingredient, and to their use in therapy and in cosmetics.
Claims11
A process for preparing high-density quercetin comprising roller compaction of quercetin,
- wherein both the high-density quercetin and the quercetin starting material have a purity of at least 95%,
- wherein the high-density quercetin has a bulk density of more than 0.50 g/ml and a Carr index below 15,
- wherein the high-density quercetin is in granules, and
- wherein a roll speed for the roller compaction is in a range from 1-1.6 rad/s.
