Abstract

From CATHARANTHUS ROSEUS cell suspension cultures 16 R-19,20- E-isositsirikine ( 1), 16 R-19,20- Z-isositsirikine ( 2) and a new sarpagine type indole alkaloid ( 5) have been isolated. The structures have been deduced from spectroscopic data; that of 5 has been confirmed by X-ray analysis.
