“…In view of the study proposed by Nunes et al (2021), the EO Thymus vulgaris presented 23 substances that were evaluated by analysis (GC/MS), being carvacrol (26.14%), p-cymene (23.75%) and thymol (21.78%). Other authors also classify these chemical constituents thymol (53.5%), p-cymene (20.8%) and carvacrol (8.9%) as major secondary metabolites (Porto et al, 2021). It is noteworthy that the variations in terms of results obtained by the mentioned studies are due to the fact that the isomers thymol and carvacrol are biosynthesized based on γterpinene and ρ-cymene, which contribute to the identification of these compounds (Nunes et al, 2021).…”

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