“…This strong activity is already demonstrated in more recent studies such as that of Etchike et al (16), which demonstrated the bactericidal effect on E. coli with a MIC of (1.47×10) − 2. The same observation was already made rather by Xaserra et Sharma (1999), but this time with the essential oils of the plant. The aqueous and ethanolic extracts of the leaves of Phyllantus amarus were inactive on P. aeruginosa and E. coli.…”

SummaryObjectives. This study aims to evaluate the antibacterial and chemical properties of some medicinal plants used in the fight against enteropathogens in Benin.Methods. Aqueous and ethanolic extracts of Senna siamea, Uvaria chamae, Lantana camara and Phyllantus amarus were tested on 10 bacterial strains. Well diffusion technique, coupled with the microdilution determination of Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (CMB) was used for antibacterial testing. The larval cytotoxicity was evaluated by using Artemia salina crustacean larvae. flavonoids and polyphenols were also assayed by the method using aluminum trichloride (AlCl3) and the method using the folin-Ciocalteu reagent, respectively.Results. The results of the study revealed that extracts had an effective antibacterial activity at 100 mg/mL, with MIC between 100 and 25 mg/mL and CMB between 100 and 50 mg/mL. The inhibition diameters of the extracts varied between 7.5 and 21 mm. The ethanolic extract of Phyllantus amarus leaves showed the best antibacterial activity. None of the extracts tested was found to be cytotoxic at the dose of 20 mg/mL. The aqueous Uvaria chamae root extract has the highest polyphenol content (231.896552±0.27586207 in μg EAG/100 mg extract), whereas the aqueous leaf extract of Uvaria chamae is the richest in flavonoids (41.061082 0.43180737 in μg ER/100 mg of extract).Conclusions. These interesting results can be used in the development of improved traditional medicines against enteropathogens. IntroductionInfections caused by enteropathogens are serious forms of infectious pathology. They are a major public health problem that causes millions of deaths a year. This is the case, for example, of foodborne illnesses, causing 17 million deaths a year worldwide, more than half of which come from the African continent (37). Diarrheal diseases are also the cause of 550 million patients each year, including 220 million children under 5 years of age (37). Salmonella, shigella and klebsielles are amongst others epidemiologically active enterobacteria involved in serious infectious diseases.Health management of enteropathogenic diseases is achieved through the use of antibiotics, but their inadequate and often anarchic use has resulted in bacterial resistance (24,36). Indeed, recent data from the bibliography abound with descriptions of bacteria that are multiresistant or even toto-resistant to antibiotics. The number of these bacteria is increasing in both industrialized and developing countries (32). This development of microbial resistance to antibiotics has led researchers to carry out alternative investigations to identify other effective natural remedies against various pathologies in the plant kingdom (18). It has therefore proved essential to look for new antibacterial substances that are effective and have a broad spectrum of action. One of the effective strategies for this research is to explore plants used in traditional Correspondence: Victorien T. Dougnon, Lecturer-Researcher in Microb...

“…Brazil, Cuba, India, Jordan and Mexico are examples of countries that have a diverse flora and a rich tradition in the use of medicinal plants for both antibacterial and antifungical applications (Martínez et al, 1996;Navarro et al, 1996;Mahasneh et al, 1999;Ahmad and Beg, 2001;Rehder et al, 2004). Similar phenomena are also reported throughout the world (Grosvenor et al, 1995;Silva et al, 1996;Saxena and Sharma, 1999;Nimri et al, 1999).…”

“…The substances that can either inhibit the growth of pathogen or kill them and have no or least toxicity to host cells are considered candidates for developing new antimicrobial drugs. The antimicrobial properties of medicinal plants are being increasingly reported from different parts of the world (Saxena, 1999). It is expected that plant extracts showing target sites other than those used by antibiotics will be active against drug resistant microbial pathogen Kaempferia galanga L. is one of the valuable medicinal plants in Zingiberaceae family, an aromatic rhizomatous herbal spice, is an ingredient of many aurvedic drug preparations (Sadimann 1992).…”
