Toxicology

The seeds of the tree Balanites aegyptiaca have a molluscicide effect on Biomphalaria pfeifferi.[8]

Substance Route LC50 Reference
Powder of crude kernels of Balanites aegyptiaca immersion(?) 60 ppm [8]
Acetone extract of powder of the kernels of Balanites aegyptiaca immersion(?) 172,40 ppm [8]
Ethanol extract of the powder of kernels of Balanites aegyptiaca immersion(?) 84,15 ppm [8]

Ethanolic extract of the fruits of Dalbergia sissoo (family Leguminosae) exhibited molluscicidal effect against eggs of Biomphalaria pfeifferi.[9]
