dc.description.abstractIntroduction: Hyptis obtusiflora C. Presl ex Benth (ollamepan) and Himatanthus tarapotensis (K. Schum. ex Markgr.) Plumel (bellaco caspi) present secondary metabolites with the capacity to inhibit strains of Streptococcus mutans, responsible for the development of dental caries. Objectives: To evaluate the antibacterial effect of hydroalcoholic extracts of ollamepan and bellaco caspi on Streptococcus mutans. Methods: Experimental, in vitro and comparative study. A preliminary phytochemical assay of both extracts was performed. Sixty Müller-Hinton agar plates (Merck®) were used, divided into 4 groups (n= 15): group I (70% ethanol), group II (0.12% chlorhexidine), group III (25% ollamepan), group IV (25% bellaco caspi). The disc diffusion technique described by Bauer and Kirby was used; the strain used was Streptococcus mutans ATCC 25175 and the inhibition diameters were measured at 24 h to determine the antibacterial effect. Results: In the phytochemical assay, phenolic compounds and tannins were detected in both extracts. The antibacterial effect of group III was confirmed with 18.660 ± 0.0948 mm (95.54%) and group IV with 19.383 ± 0.0845 mm (99.24%), comparable with 0.12% chlorhexidine (group II) 19.532 ± 0.0975 mm (100%) on Streptococcus mutans ATCC 25175. Conclusions: Hydroalcoholic extracts of both species have antibacterial effect in vitro on Streptococcus mutans ATCC 25175 strains. However, Himatanthus tarapotensis (K. Schum. ex Markgr.) Plumel at 25% shows antibacterial effect with values similar to chlorhexidine at 0.12%.en_US
dc.description.abstractIntroducción: Hyptis obtusiflora C. Presl ex Benth (ollamepan) e Himatanthus tarapotensis (K. Schum. ex Markgr.) Plumel (bellaco caspi) presentan metabolitos secundarios con capacidad de inhibir cepas de Streptococcus mutans, responsable del desarrollo de caries dental. Objetivos: Evaluar el efecto antibacteriano de los extractos hidroalcohólicos de ollamepan y bellaco caspi sobre Streptococcus mutans. Métodos: Estudio experimental, in vitro y comparativo. Se realizó un ensayo fitoquímico preliminar de ambos extractos. Se utilizaron 60 placas de agar Müller-Hinton (Merck®), repartidas en 4 grupos (n= 15): grupo I (etanol al 70 %), grupo II (clorhexidina al 0,12 %), grupo III (ollamepanal 25 %), grupo IV (bellaco caspi al 25 %). Se empleó la técnica de difusión con discos descrita por Bauer y Kirby; la cepa utilizada fue Streptococcus mutans ATCC 25175 y las mediciones de los diámetros de inhibición se realizaron a las 24 h, para precisar el efecto antibacteriano. Resultados: En el ensayo fitoquímico se detectaron compuestos fenólicos y taninos en ambos extractos. Se confirmó el efecto antibacteriano del grupo III con 18,660 ± 0,0948 mm (95,54 %) y grupo IV con 19,383 ± 0,0845 mm (99,24 %), comparables con clorhexidina al 0,12 % (grupo II) 19,532 ± 0,0975 mm (100 %) sobre Streptococcus mutans ATCC 25175. Conclusiones: Los extractos hidroalcohólicos de ambas especies tienen efecto antibacteriano in vitro sobre cepas de Streptococcus mutans ATCC 25175. Sin embargo, Himatanthus tarapotensis (K. Schum. ex Markgr.) Plumel al 25 % presenta efecto antibacteriano con valores semejantes a clorhexidina al 0,12 %.es_PE
