Fasciolosis is an anthropozoonosis of clin. and economic importance that affects several mammals. The causative agent, Fasciola hepatica, has as an obligate intermediate host, the snail Pseudosuccinea columella; therefore, control actions against the mollusks are essential to control the disease. This study aims to evaluate the effect of volatile oils of Origanum vulgare L. and Thymus vulgaris L., both species members of Lamiaceae family, and their resp. major compounds, carvacrol and thymol, as an alternative in the control of the American ribbed fluke snail. The specimens were immersed in solutions with concentrations of 0.025% (mv-1), 0.05% (mv-1), and 0.1% (mv-1) and analyzed at 30 min, 2 h, 6 h, 12 h, and 24 h in relation to motility, adhesion in the plate, response to painful stimulus, and mortality. For ovigerous masses, the interruption or not of embryonic development was analyzed, with observations every 72 h up to 18 days. All compounds promoted the mortality of mollusks and the paralysis of the embryonic development. The test constituents promoted mortality after 30 min. Histol. analyses indicated the occurrence of necrosis, mainly in the digestive gland and in the albumen gland and disorganized connective tissue. In the experiment, the researchers used many compounds, for example, 5-Isopropyl-2-methylphenol (cas: 499-75-2Recommanded Product: 5-Isopropyl-2-methylphenol).
5-Isopropyl-2-methylphenol (cas: 499-75-2) belongs to alcohols. The oxygen atom of the strongly polarized O鈥旽 bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Recommanded Product: 5-Isopropyl-2-methylphenol
