Summary
Schistosomiasis is a parasitic disease caused by the parasite of the genus Schistosoma. In the reproductive cycle, the worm presents as hosts the human being (definitive) and snails of the genus Biomphalaria (intermediate). Control of mollusks by WHO is done through Niclosamide. This molluscicide has high environmental impact and cost. The objective of this work was to search for studies that demonstrate the importance of secondary metabolites in the development of efficient and low cost natural molluscicides. It was selected studies held at UFMA from 2006 to 2016 (final course works, scientific initiation works and articles published in periodicals). The plant species studied were Caryocar brasiliense, Syzygium jambolanum, Momordica charantia, Luffa aegyptiaca, Jatropha gossypiifolia and Avicennia schaueriana. The plant extracts that presented molluscicidal activity were J. gossipiifolia (100% mortality at 25 ppm concentration), S. jambolanum (100% at 0.100 mg / mL), C. brasiliense (100% at 0.17 mg / mL) and M. charantia (85% at 100 ppm). These four species had the highest concentration of saponins and/or tannins. The species A. schaueriana and L. aegyptiaca were devoid of these metabolites and had no molluscicidal effect. The molluscicidal activity of plant extracts is mainly due to the presence of saponins and tannins. The saponins act by lysing the cell membranes of the snails and causing their contents to overflow. The action of tannins, when complexed with proteins and digestive enzymes, affect the use of vitamins and minerals. It can be concluded that the regional plants wich are supplied with saponins and tannins can be considered as potential instruments in the fight against the expansion of schistosomiasis.
