Abstract
Abstract
Nowadays, due to the indiscriminate use of drugs and the consequent increase in antibiotic resistance, the tendency towards the use of medicinal plants is increasing because of their fewer side effects. Most plants produce compounds called secondary metabolites that possess numerous properties, including antimicrobial effects. On the other hand, dental caries is a common oral disease, and various factors, including nutrition, influence it. In this study, the antimicrobial effects of hydroalcoholic extracts of fruit (HEPFF) and root of Prosopis farcta (HEPFR) on cariogenic Streptococci, including Streptococcus mutans, Streptococcus sanguis, Streptococcus salivarius, and Streptococcus sobrinus, as well as food poisoning bacteria (Escherichia coli, Salmonella typhimurium, and Staphylococcus aureus) were investigated under laboratory conditions. The extracts were prepared using the ultrasound-assisted extraction method, and then their total phenolic content and total flavonoid content were determined separately. The antimicrobial properties of these extracts were evaluated by the well diffusion method and by determining (MIC) and (MBC) values. The results showed that (HEPFF) had higher total phenolic content and total flavonoid content compared to (HEPFR) (P < 0.05). Furthermore, (HEPFF) exhibited stronger antimicrobial activity against all examined strains compared to (HEPFR). Therefore, it can be concluded that (HEPFF) has desirable antimicrobial properties and can be utilized in the food and pharmaceutical industries.
