[Identification of N,N-dimethyl-O-(beta-D-glucopyranuronosyl)-5- hydroxytryptamine as a bufotenine metabolite in the rabbit].

A bufotenine metabolite has been isolated from the rabbit urine by the column chromatography on cellulose and preparative paper electrophoresis in acidic buffer. It has the structure of N,N-dimethyl-O-(beta-D-glucopyranuronosyl)-5-hydroxytryptamine as proved by comparison of chromatographic, electrophoretic and NMR data with those for respective synthetic O-glucuronide.
