Japanese Patent JPH05502457
Kind Code:
A
Abstract:
Described is a dry kava extract with a total kavalactone content of at least 50 % by wt. and a flavokavin content of at the most 0.3 % by wt. The extract is readily soluble in water and has high bio-availability following oral administration. In order to increase the kavalactone content and decrease the flavokavin content of the extract, a method is proposed in which the raw extract is brought into solution and the flavokavin content reduced by cold precipitation or by solvent partition, after which the solution is concentrated to dryness. The dry extract can be used to prepare drugs.
