Barbosa-Filho, Auteur Année de publication : 2007 Article en page(s) : pp. 482-484 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Ocotea bracteosa Lauraceae Essential oil composition δ  -cadinene Ledene Globulol Molluscicidal activity Résumé : 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.
