In the current research, alkaloid extract obtained from the seeds of' Heliotropium europaeum L. collected from Köprübaşi (Diyarbakir, Turkey) was analysed by using GC-MS method. The total pyrrolizidine alkaloid and tertiary base content of the seeds of Heliotropium europaeum were found to be 0.28 % and 0.02 % respectively. Higher percentage of alkaloids were present as N-oxides (92.86 % of the alkaloids). Alkaloids found in the tertiary base fraction and total alkaloid fraction were identified as europine, heliotrine, supinine, heleurine, lasiocarpine and 7-angelylheliotrine.
