Composition and molluscicidal properties of essential oils from leaves of xylopia iangsdorffiana A. st. hil. et tul. (Annonaceae) / Josean F. Tavares in The journal of essential oil research, Vol. 19 N°3 (Mai/Juin 2007)

(Annonaceae) Type de document : texte imprimé Auteurs : Josean F. Tavares, Auteur ; Marianna V. B. Silva, Auteur ; Karine F. Queiroga, Auteur Année de publication : 2007 Article en page(s) : pp. 282-284 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Xylopia langsdorffiana Annonaceae Essential oil composition Germacrene D Trans-β  -guaiene β  -caryophyllene Molluscicidal activity Résumé : The volatile fraction of Xylopia langsdorffiana leaves was analyzed by GC and GC/M S and tested for molluscicidal activity. With this methodology 19 different components were identified in the oil. Among them, germacrene D (22.9%), trans-β-guaiene (22.6%), β-caryophyllene (15.7%), and α-pinene (7.3%) were found to be the major constituents. The oil showed significant molluscicidal activity against Biomphalaria glabrata, with an LC90 value of 5.6 μg/mL, which falls below the threshold of 100 μg/mL, set for potential molluscicidal activity by the World Health Organization.
