In the present study methanol and aqueous extract of the medicinal plant Desmodium gyrans were tested for the antimicrobial and wound healing properties. The antimicrobial activity of this plant was tested against the clinical pathogens such as Escherichia coli, Salmonella typhi, Staphylococcus aureus, Vibrio cholerae and Klebsiella pnemoniae. The methanol extract of this plant showed efficient antimicrobial activity against clinical pathogens such as Escherichia coli, Vibrio cholerae and Staphylococcus aureus. The aqueous extract of this plant was found to be effective against Klebsiella pnemoniae and Staphylococcus aureus. The phytochemical screening of this plant revealed the presence of the phytoconstituents such as alkaloids, steroids, tannins and saponins. The aqueous extract of this plant was found to be effective in healing the wounds when it was tested in rabbits of Orychtolacus sp and this was compared with standard antibiotic cream...

Patients with chronic dental infection are usually treated with antibiotics. However, the value of antibiotics was decreasing because increased resistance in bacteria. The objective of this study is to evaluate the efficacy of herbal crude extract of Mentha arvensis in human Cariogenic pathogens. In this study we obtained crud extract of Mentha arvensis in different solvent 50% and 10% methanol, ethyl acetate, chloroform and was tested against human Cariogenic pathogens Streptococcus mutans, Streptococcus sangunis, Staphylococcus aurues, Lactobacillus casei were isolated from patients having dental disease. The crude extracts activity were studied by disc diffusion and both dilution methods in different concentration. Studies were also undertaken to assess the phytochemical composition of the Mentha arvensis extract. 50% methanolic extract at 2.5mg/ml and 5mg/ml concentration shows slightly bigher zone of inhibition (ranging from 26 to 30 mm and 28 to 32 mm), and 10% methanolic 2.5mg/ml and 5mg/ml extract shows slightly small zone (ranging from 20 to 24 mm and 22 to 27 mm) and comparison with ethyl acetate and chloroform...

In Ethiopian traditional medicine, the aqueous decoction of the leaves of Cineraria abyssinica Sch. Bip. exA. Rich (Asteraceae) is used for treatments of various ailments including diarrhea, however, to date, there appear to have been no reports on the phytochemistry and the antimicrobial activity of the plant. The main aim of this study was, therefore, to carry out preliminary phytochemical screening and antimicrobial activities on leaf extracts of C. abyssinica. The in vitro antimicrobial activities of the aqueous and 80% methanolic crude extracts of the leaves of C. abyssinica were investigated against Gram positive and Gram negative bacteria by agar disc diffusion method. Both the aqueous and 80% methanolic extracts showed various degrees of potent antibacterial activities comparable to the standard drug ciprofloxacin against all of the bacteria tested except Bacillus species. Preliminary phytochemical screening of the plant revealed the presence of polyphenols, flavonoids, coumarins, saponins, terpenoids and phytosterols. The acute toxicity studies showed the nontoxic nature of the plant up to 3 g/kg. Therefore, the present study revealed...

This study aimed to discover the antibacterial effect of Acmella oleraceae against dental caries bacteria and aware the populace about the importance of using phytomedicines. According to this study, the antibacterial effects of Acmella oleraceae was checked against the dental caries bacteria using well diffusion method. Phytochemical screening of Acmella oleracea checked with chloroform, ethanol, methanol and water and acetone extracts. Screening tests revealed that this plant is a big source of phytochemical compounds. The phytochemical analysis of Acmella oleracea is conducted using Thin Layer Chromatography (TLC).Acetone solvent system of Acmella oleracea showed two spots with highest Rf value 0.922. Three compounds were obtained in the chloroform solvent system with highest Rf value of...

An ethnomedicinal plant, Hugonia mystax L., was examined for preliminary phytochemical screening and antimicrobial activity. Preliminary phytochemical screening showed the presence of various classes of secondary metabolites such as flavonoids, phenols, saponins, steroids, tannins and terpenoids. Antimicrobial activity of petroleum ether, chloroform, ethanolic and aqueous fruits extracts showed significant activity against the human pathogens such as Streptococcus pneumoniae causing brain abscesses, pneumonia and septic arthritis; Proteus vulgaris, Pseudomonas aeruginosa causing urinary tract infections and septicaemia; Salmonella typhi causing typhoid fever, Vibrio species causing diarrheal infections and the fungus Candida albicans causes urinary tract infections. The antimicrobial activity of the petroleum ether, chloroform, ethanolic and aqueous fruits extracts showed concentration-dependent activity against all the tested bacteria at various concentrations. Thus, the present findings revealed the medicinal potential of H. mystax to develop a drug against various human...
