VILCHEZ CACEDA, Héctor Alexander; OLORTEGUI QUISPE, Antonella Rosario y ALVIA SALDARRIAGA, Christhian Alexander. Antibacterial effect of hydroalcoholic extract of Solanum sessiliflorum Dunal (cocona) on Streptococcus mutans. Rev. cuban. med. mil. [online]. 2023, vol.52, n.1 Epub 01-Mar-2023. ISSN 1561-3046.
Introduction:
The search for new extracts of plant origin with antibacterial properties to maintain oral health is essential for the optimal performance of military personnel.
Objectives:
To evaluate the antibacterial effect of the hydroalcoholic extract of Solanum sessiliflorum Dunal (cocona) on Streptococcus mutans.
Methods:
In vitro and comparative experimental study. A preliminary phytochemical assay of the hydroalcoholic extract of Solanum sessiliflorum Dunal was performed. Forty-eight Müller-Hinton agar plates (Merck®) were used, distributed in 6 groups (n= 8). Group I (distilled water), group II (70% ethanol), group III (0.12% chlorhexidine), group IV (25% Solanum sessiliflorum Dunal), group V (50% Solanum sessiliflorum Dunal) and group VI (75% Solanum sessiliflorum Dunal); the disc diffusion technique described by Bauer and Kirby was used; the strain used was Streptococcus mutans ATCC 25175 and the inhibition halos were measured at 24 hours to determine the antibacterial activity.
Results:
Phenolic compounds, anthocyanins, quinones and cardiotonic glycosides were detected in the phytochemical assay. The antibacterial effect of group VI (Solanum sessiliflorum Dunal 75%) was proven with 19,831 ± 0,0553 mm (99,37%), comparable to that of 0,12% chlorhexidine (group III) 19,956 ± 0,0431 mm (100%) on Streptococcus mutans ATCC 25175.
Conclusions:
The 75% hydroalcoholic extract of Solanum sessiliflorum Dunal shows in vitro antibacterial effect on Streptococcus mutans ATCC 25175 strains with values similar to 0,12% chlorhexidine.
