Abstract

CAMACHO-CAMPOS, Conrado et al. Phytochemical, antibacterial and molluscicidal evaluation of leaf extracts of Agave spp. Rev Cub Quim [online]. 2020, vol.32, n.3, pp. 390-405.  Epub Dec 03, 2020. ISSN 2224-5421.

The aim of the present work was to evaluate the phytochemical, antibacterial and molluscicidal properties of Agave americana and Agave angustifolia. The leaves were washed, dried and pulverized. It was determined the presence of primary and secondary metabolites in aqueous and hydro-alcoholic extracts. The antibacterial activity of the hydro-alcoholic extracts was determined against Staphylococcus aureus and Escherichia coli, by using the well diffusion method. The molluscicidal activity of the aqueous extracts was assayed against Praticolella griseola. Terpens, flavonoids, saponins, steroids, tannins, coumarins and cardiac glycosides were found in both plant species. A. angustifolia showed the higher antibacterial activity against S. aureus (22,7 mm) and E. coli (16,0 mm). Agave americana showed a high molluscicidal activity with a mortality of 100 % after 4 h of extract application. The results suggest the potentialities of both plant species as sources of metabolites with antibacterial and molluscicidal activities.

Keywords : agave; antibacterial; bio-pesticide; Praticolella; secondary metabolites.
