Abstract:
Two pyrrolizidine alkaloids, megalanthonine (1) and lycopsamine (2), have been isolated from Heliotropium megalanthum. The structure of the novel compound 1 was determined by spectroscopic methods. The insecticidal, antifeedant, and antifungal effects of compounds 1 and 2 have been evaluated.
