ESPINOSA-MORENO, Judith et al. In vitro antihelmintic activity of three plant species traditionally used in Tabasco, Mexico. Polibotánica [online]. 2016, n.41, pp.91-100. ISSN 1405-2768.  https://doi.org/10.18387/polibotanica.41.6.

Antihelmintic activity against Haemonchus contortus was searched as a new alternative for animal health improvement using three plants (Cydista aequinoctialis L., Heliotropium indicum L. and Momordica charantia L.) of traditional usage in the rural area of Tabasco State, Mexico. Aqueous extracts were obtained of dried material. Each extract was diluted in distilled water to obtain a concentration of 20 mg ml-1. The antihelmintic activity was evaluated at 24, 48 y 72 h of exposition with 100 μL of each extract and 50 L3 unsheathed larvaes of H. contortus in a 96 well ELISA plaque. Distilled water was used as negative control and fenbendazole as positive control. All extracts of the three studied plants presented antihelmintic activity and the highest mortality, 65.5% at 72 h, was recorded with the M. charantia fruit extract.
