Abstract
An aqueous extract of valerian roots is concentrated to concentrate the extract and to eliminate odors which are volatile and which are produced by degradation products of valepotriates. An alcohol or acetone is added to the concentrated valerian extract to precipitate insoluble solids from the concentrated extract. The precipitated solids are separated from the extract, after which the extract is mixed with a carbohydrate and then dried to obtain a powder.
