Investigation of the pyrrolizidine alkaloids of Heliotropium arbainense resulted in the isolation and identification of heliotrine, europine and 7-angelylheliotrine. From H. ovalifolium three alkaloids were isolated: supinine, 7-angelylheliotridine and an alkaloid which was shown to be of the heliotridine monoester type with a dehydrated viridifloric acid.
