Heliotropium bovei was shown to contain lasiocarpine, europine, 5'-ace
tyllasiocarpine and a new alkaloid 7-acetyleuropine. Lasiocarpine N-ox
ide and 5'-acetyllasiocarpine N-oxide are also present in this plant s
pecies. These structures were established from spectral and chemical s
tudies including 2D NMR. Europine showed both antifungal and insect an
tifeedant activity, while 7-acetyleuropine was inactive.
