“…All of the used MTCC (Microbial Type Culture Collection) bacterial strains were collected from Institute of Microbial Technology (IMTECH), Chandigarh. Antibacterial activity was done using slight modification of standard methods of Agar Well Diffusion assay (Allen, Molan, Reid, 1991), Disc Diffusion method (Scorzoni et al, 2007;Amanda et al, 2012;Zare et al, 2012;Thompson et al, 2013) and Broth dilution assay (Rai et al, 2010).…”

Dioscorea pentaphylla L., a wild tuber is used both as food and medicines among different ethnic groups of Similipal Biosphere Reserve, India. Tubers are used against skin infections. In order to establish and confirm tribal claims, methanol extract was subjected to fractionation. The active fraction (DP1) was subsequently used for further purification and NMR (Nuclear magnetic resonance) characterization. The phytochemical analysis revealed the presence of saponin groups. The antibacterial activity of DP1 was done against selected bacterial strains (Salmonella typhi, Shigella flexneri, Streptococcus pyogenes, Streptococcus mutans and Vibrio cholerae) using DD (disc diffusion), AWD (agar well diffusion) and broth dilution assay. The activity was compared with antibiotics Penicillin and Kanamycin. It was observed that DP1 showed significant inhibitory activity against the tested bacteria. The characterization of DP1 through NMR analysis and presence of proton in carbon position at C-3, C-19, C-18, C-21 and C-27 was same as the known compound "Diosgenin". Therefore, isolated compound was confirmed to be Diosgenin. The study for the first time showed that, diosgenin present in D. pentaphylla tuber was responsible for antibacterial and antioxidant potential. Present study highlights the importance of Dioscorea species as sources of diverse secondary metabolites for the isolation of active compound(s).

Leaf blight of potato and tomato caused by Alternaria solani is an important fungal disease that causes heavy loss to the growers. In case of suitable conditions the pathogen causes maximum damage to these vegetable crops and even the fruits of tomato are also attacked by the pathogen. In the present study the pathogens was isolated and pure culture was maintained on Potato Dextrose Agar medium. In vitro experiments were done to evaluate the fungitoxic effects of three different concentrations of 7 selected fungicides as well as leaf extracts of 7 different plants extracts separately. Among the fungicides, 100 inhibition was found when 2000 ppm of Difenconazole, Propinconazole and Benomyl was used. Diphenconazole and Propinconazole even at 1000 ppm, completely inhibited the mycelial growth of the pathogen in vitro. Lowest percentage of inhibition of mycelial growth was found in case of copper hydroxide. Even at 2000 ppm the percentage of inhibition was 68.72 only. Similarly, Thiophenate at 2000 ppm could inhibit the mycelial growth that was 78.85 only. Among the phytoextracts, leaf extract of Acasia nilotica at 30 inhibited 84.74 of mycelial growth, which was followed by the extract taken from the cloves of Allium sativa. At 30 the percentage of inhibition was 81.65. This was followed by the percentage of inhibition by leaf extract of Azadirachta indica, which were 78.54 at 30. Minimum inhibition at 30 of leaf extract of Phyllanthus niruri was 68.66. In the present work it was noted that mycelial growth was inhibited at all the concentrations of the seven fungicides and leaf extracts of all the plants with different percentages of inhibition.

“…A partir do extrato metanólico das folhas e flores de L. nodiflora, Zare et al (2012), constataram a atividade antimicrobiana dessa espécie contra 4 bactérias gram-negativas (Kelebsiella oxytocal, K. pneumoniae, Pseudomonas aeroginosa e Escherichia coli), 4 gram-positivas (Staphylococcus aureus, Bacillus subtilis, B. cereus e Micrococcus luteus) e 2 fungos (Candida albicans e Aspergillus niger). A atividade observada pode ser atribuída a presença de terpenóides, sesquiterpenóides e ácido fenólico.…”

-(Antimicrobial activity and therapeutic potential of the genus Lippia sensu lato (Verbenaceae)). The growing number of infectious diseases combined with the continuous increase of antimicrobial resistance of certain microorganisms justify the constant search for new drugs. Given this situation, plants are a rich source of bioactive resources of pharmacological interest. The Verbenaceae family, especially the genus Lippia L., has representatives with potential already confirmed against various pathogens; the species of Lippia are widely used in folk medicine for their anti-inflammatory, antifungal, antiseptic, anti-hypertensive, anxiolytic, anti-leishmania, antiviral, and digestive properties, among other applications. This review gathers information about the antimicrobial potential of the main species of the genus Lippia, relating to the type of extract, its constituents, and the importance of this genus in the investigation of natural products and their phytochemical and biological characteristics. Keywords: antibiotics, antifungals, phytochemical composition, natural products, tribe Lantaneae RESUMO -(Atividade antimicrobiana e potencial terapêutico do gênero Lippia sensu lato (Verbenaceae). O crescente número de doenças infecciosas somado ao aumento contínuo da resistência antimicrobiana de determinados micro-organismos justificam a busca constante por novos fármacos. Diante dessa situação, os vegetais representam uma fonte rica de recursos bioativos de interesse farmacológico, dentre os quais a família Verbenaceae, que possui representantes com potencial já confirmados contra diversos agentes patogênicos, especialmente o gênero Lippia L., cujas espécies são muito utilizadas na medicina popular por possuírem propriedades anti-inflamatória, antifúngica, antisséptica, anti-hipertensiva, ansiolítica, anti-leishmania, antiviral, digestivas, entre outras aplicações. A presente revisão reúne informações acerca do potencial antimicrobiano das principais espécies do gênero Lippia, relacionando ao tipo de extrato, seus constituintes e a importância desse gênero dentro da prospecção de produtos naturais, bem como suas características fitoquímicas e biológicas.
