Some 22 pyrrolidine and piperidine alkaloids were detected in the leafy parts of Sedum acre, S. aetnense, S. anglicum, S. brissemoreti, S. farinosum, S. fusiforme, S. lancerottense, S. melanantherum, and S. nudum.In addition to the alkaloids known from S. acre, 1-(2-pyrrolidyl)-propan-2-one and 2-monosubstituted piperidine alkaloids bearing butan-2-one, butan-2-ol, pentan-2-one and pentan-2-ol sidechains were identified.Phenylethylamine was isolated from the vegetative parts of S. album.In S. lydium, S. meyeri-johannis, and 16 species of S. series Rupestria, Aeonium, Greenovia, Jovibarba and Sempervivum no alkaloids could be detected.The results indicate a correlation between the presence of alkaloids and the major evolutionary trends in the European and Macaronesian Crassulaceae. Key Word Index: Sedum; Aeonium; Greenovia; Jovibarba; Sempervivum; Crassulaceae; pyrrolidine and piperidine alkaloids; chemotaxonomy; evolution.
