Abstract
The determination of the constituents of crude drugs in drinkable preparations by high performance liquid chromatography was established. As a result of the examination about the crude drugs which were blended in 16 kinds of commercial drinkable preparations, Epimedii Herba, Ginseng Radix and Royal jelly had more blending frequency or contents. So the determination of icariin, ginsenoside Rg1 and 10-hydroxy-2-decenoic acid which were characteristic constituents of each crude drug was established. The determination of hypoxanthine which was isolated from Cervi Parvum Cornu and had monoamine oxidase inhibitory activity, and choline which was found in Cistanchis Herba and Epimedii Herba much more than other crude durgs in 16 kinds of drinkable preparations was also established. The contents of each constituent in several kinds of drinkable preparations were determined by these established methods.
