Molluscicidal activity against Biomphalaria glabrata of the bioactive nanoemulsion of the essential oil of Thymus vulgaris Linn (Thyme)

This study evaluated the molluscicidal activity against schistosomiasis-transmitting snail (Biomphalaria glabrata) of nanoemulsion Thymus vulgaris L. essential oil. The plant material was collected in municipality São Luís (MA). oil extracted by hydrodistillation at 100 °C for 3h, with chemical characterization performed Gas Chromatography coupled to Mass Spectrometry (GC-MS). nanoemulsions were prepared using phase inversion method. For activity, methodology recommended Who performed, being LC50 their action obtained Probit major constituents found carvacrol (27.35%) and thymol (24.12%). presented an 15.04 mg L-1. results indicate that is composed substances provide encourage its application, due high potential Biomphalaria glabrata.
