• Psychotria sp.
• ceramide
• psychotramide A-D
• structure determination

Chemical study of the Psychotria sp. led to the isolation of a new type of ceramide named psychotramide (1). HR-FAB-MS analysis revealed that psychotramide consists of four new sphingolipids. Their structures were determined on the basis of the spectroscopic data and chemical methods to be psychotramide A (1-a), psychotramide B (1-b), psychotramide C (1-c) and psychotramide D (1-d).
