Molluscicidal activity of Nerium indicum bark.
The molluscicidal activity of Nerium indicum bark against Lymnaea acuminata snails was studied. The toxicity of different bark preparations was both time and dose dependent. The 24-h LC50 of the lyophilized aqueous extract of bark was 34.5 mg/l whereas that of lyophilized boiled water extract was 42.5 mg/l. Low concentrations of vacuum-dried ethanolic extract (24-h LC50: 4.9 mg/l) and purified bark (24-h LC50: 0.87 mg/l) were effective in killing the test snails.
