Two new pyrrolizidine alkaloids, hackelidine (I) and 7-acetylhackelidine (II), which probably occurred as their N-oxides, were isolated from H. californica (Boraginaceae) after zinc reduction Their structures were established from 1H NMR, 13C NMR and MS spectra. Oxidation of II with H2O2 gave its N-oxide.

Key words: ALKALOID, MOLECULAR STRUCTURE, PYRROLIZIDINE ALKALOID, BORAGINACEAE
