Abstract

Three pyrrolizidine alkaloids were isolated from Eupatorium portoricense and their structures elucidated by spectroscopic methods as (-)-viridifloryl-supinidine (amabiline), (-)-viridifloryl-heliotridine (echinatine), and C12-O-acetyl-(-)-viridifloryl-heliotridine (O ¹²-acetylechinatine).
