The aim of this work was to carry out the phytochemical screening and antimicrobial activities of Haematostaphis barteri. The method of cold maceration was used in the extraction by serial exhaustive extraction method which involves successive extraction with solvents of increasing polarity from a non-polar (hexane) to a more polar solvent (methanol) to ensure that a wide polarity range of compound could be extracted. The results showed that flavonoids, terpenes, terpenes, tannins, and saponins are present in all the leaf extracts. The result of the antimicrobial activity obtained from the extracts of the leaf of Haematostaphis barteri revealed that all the crude extracts of the leaf inhibited or exhibited antibacterial activity against Salmonella paratyphi, Staphylococcus aureus, Escherichia coli, and Penicillium spp. All the extracts did demonstrate antimicrobial activity against Aspergillus niger. The plant H. barteri is commonly used traditionally for the treatment of diarrhoea, wound, headache, malaria, dysentery and fevers. The overall results confirm the significance of the use of the plant in traditional medicinal treatment of diarrhea, wound, headache, malaria, dysentery and fevers, in line with reported claims.

It is well known that essential oils possess significant antimicrobial activity. This study was conducted to estimate the antimicrobial activity of various types of Biokill, a laboratory produced solution composed of several essential oils (Biokill dissolved in 96% ethanol; Biokill 96% further dissolved in DMSO; Biokill dissolved in 70% ethanol and Biokill 70% further dissolved in DMSO). The antimicrobial activity was evaluated against five selected fungal strains, Candida albicans ATCC 10231, Saccharomyces cerevisiae ATCC 9763, Aspergillus niger I.N. 1110, Aspergillus sojae CCF and Penicillium spp. FNS FCC 266. A variation of the microtiter plate-based antimicrobial assay was used in order to assess the antimicrobial activity of the solutions. By applying this assay minimal inhibitory concentrations (MIC) of the Biokill solutions were determined for each strain of the selected test microorganisms. The results demonstrated that all variations of Biokill showed antimicrobial activity at concentrations lower than 2.5?g/mL. Biokill 70% further dissolved in DMSO showed the best antimicrobial properties against all the selected strains with MICs less than 1.25?g/mL. These results indicated that Biokill could find application in the pharmaceutical industry, in food preservation and conservation, in the prevention and treat?ment of plants infected by certain phytopathogens, etc.

The present study to determine the possible phytochemicals and antimicrobial activity of various leaf extracts of Crinum defixum Ker - Gawler plant. The phytochemical screening demonstrated the presence different types compound like flavonoids, tannins, phenolic compounds, saponins and glycosides. The ethanol, methanol and crude extracts of Crinum defixum Ker - Gawler showed significant antibacterial activity against Escherichia coli, Staphylococcus aureus, pseudomonas aeruginosa, proteus vulgaris and antifungal activity against Candida albicans, Aspergillus flavus when compare to different concentrations (μg/mL). The antimicrobial potential of test compounds was determined on the basis of mean diameter of zone of inhibition around the disk in millimetres. Thus, the present findings revealed the medicinal potential of Crinum defixum Ker - Gawler to develop a drug against various human ailments.

Screening and comparison of antimicrobial action of leaf extract of Aerva lanata and Momordica charantia. Ethyl acetate and methanolic extracts of leaves of plants were screened for antimicrobial activity using the cup plate method and the spread plate method against gram positive and gram negative reference organisms (Bacillus substilis and Escherichia coli).The standard antibacterial agent used for reference is Choramphenicol and the results were calculated as zone of inhibition. Methanolic extract showed comparatively broader and better antimicrobial spectrum than ethyl acetate extract in selected plants. Plant extracts showed dose dependent action, results were similar to the action of the standard Choramphenicol. Extracts of Aerva lanata and Momordica charantia demonstrated antimicrobial activity on tested microorganisms. Methanolic extracts showed higher antimicrobial potential than ethyl acetate extract. Aerva lanata extracts showed better response than Momordica charantia extracts in the cup plate method antibacterial activity with Bacillus substilis and Escherichia coli.

Objective: The objective of this study was to extract the phytochemicals from leaf and stem bark of Solanum pubescens, perform qualitative analysis, and evaluate antimicrobial activity of the phytochemicals against certain microbial pathogens. Methods: Leaf and stem bark of S. pubescens was subjected to phytochemical extractions using Soxhlet apparatus with five different solvents, identified the major constituents in different solvent extracts using standard protocols and investigated the potential antimicrobial activities of the extracts against certain selected bacterial and fungal pathogens by agar well diffusion method. Results: The maximum yield was in methanolic extracts of leaf and stem bark of the study plant such as 18.51 and 12.5%, respectively, followed by the hydroalcohol extracts (14.23 and 10.00%). Qualitative phytochemical analysis revealed maximum number of extracted bioactive compounds when compared to other similar studies. Among the five different solvent extracts of S. pubescens, n-hexane extract of stem bark was found to be active against all the bacterial pathogens and stem bark extracts made with methanol and hydroalcohol showed antifungal activity against all the four fungal pathogens tested. Leaf extracts made with solvents such as n-hexane and ethyl acetate showed inhibition against Klebsiella pneumoniae and Staphylococcus aureus, respectively, hydroalcohol extract was active against Pseudomonas aeruginosa and Salmonella typhimurium while none of the leaf extracts of the study plant showed inhibition zones against fungal pathogens tested. Conclusion: Multiple solvent extraction approach yielded the phytochemicals which are not yet reported and the antimicrobial activities of phytochemicals acknowledged their medicinal value.
