Resumo

Abstract The volatile oil of Ocotea bracteosa (Meisn.) Mez. stem bark was analyzed by GC and GC/MS and tested for molluscicidal activity on Biomphalaria glabrata. Twenty compounds were identified corresponding to about 70% of the oil. The major constituents were δ-cadinene (12.4%), ledene (11.1%), and globulol (10.1%). The oil showed significant molluscicidal activity against Biomphalaria glabrata, with an LC90 value of 8.3 μg/mL, which falls below the threshold of 100 μg/mL, set for potential molluscicidal activity by the World Health Organization.
