The methanolic extracts of 13 Specieis of the genus Solanum (Solanaceae) have been tested for bioactivity in Artemia salina. The extracts investigated were prepared from various parts (aerial parts, roots and fruits) of S. asperum, S. capsicoides, S. palinacantum, S. paludosum, S. paniculatum, S. paraibanum, S. sisymbriifolium, S. crinitum, S. diamantinense, S. megalonyx, S. torvum, S. asterophorum and S. stipulaceum. The lethal concentrations were determined for the extracts and among thirteen plants tested, four appear to be inactive. The extracts of the fruits of S. asperum (LC50 = 420.5 µg/mL) and S. paludosum (LC50 = 548.0 µg/mL), aerial parts of S. diamantinense (LC50 = 481.0 µg/mL) and S. sisymbrifolium (LC50 = 382.7 µg/mL), and the roots of S. asperum (LC50 = 593.4 µg/mL) and S. stipulaceum (LC50 = 823.1 µg/mL), all of which previously showed molluscicidal activity against Biomphalaria glabrata were also found to be active in the present study with brine shrimp.
