In vitro Antibacterial Activity of Hydroalcoholic and Aqueous Extracts of Echinophora platyloba against Some Pathogenic Bacteria of the Oral Cavity

Bacteria's antibiotic resistance has increased due to the use of antibiotics as a treatment strategy for pathogenic bacteria. New substances with relatively stronger antimicrobial properties are being discovered in research. Medicinal plants have become an interesting research topic due to their effectiveness against pathogenic bacteria. This in vitro study aimed to evaluate the antimicrobial properties of Echinophora platyloba DC. (hydroalcoholic and aqueous extracts) against some important pathogenic bacteria related to the oral cavity. For this purpose, samples of E. platyloba were collected from western Iran, and their extract was extracted. Subsequently, the antibacterial activity of various concentrations of the extracts was evaluated in vitro. The results showed that hydroalcoholic and aqueous extracts in all concentrations (۱۰۰, ۵۰, ۲۵, and ۱۲.۵%) could significantly inhibit the growth of all bacterial pathogens with a probability level of ۱% compared to the negative control (DMSO ۱۰۰%). Furthermore, at ۱۰۰% concentration, they were capable of suppressing the growth of bacterial pathogens (Staphylococcus epidermidis, Staphylococcus aureus, Streptococcus mutans, Streptococcus salivarius, and Streptococcus sanguis) with a significant difference (P-value < ۰.۰۱) compared to the Gentamicin antibiotic. The MIC ranged from ۳.۱۲% to ۵۰% in the present study. Therefore, the current research findings indicate that the aqueous and hydroalcoholic extracts of E. platyloba have a high potential to inhibit human pathogenic bacteria related to the oral cavity. Results of the present study will pave the way for developing novel functional pharmaceutical and food products.
