The aim of this work was to investigate of the antimicrobial and antioxidant potentials of methanol extracts from Ficus carica. Methanol extracts were screened for antimicrobial activity against different species of Gram positive andGram negative bacteria and one yeast. The methanol extract of Ficus carica showed maximum inhibition zone of 10 mm against Listeria monocytogenes. In addition to, the plant extracts were tested against the stable DPPH (2, 2-diphenyl-1-picryl-hydrazyl-hydrate) free-radical. Trolox was chosen as a standard antioxidant. Finally, the methanol extract displayed a strong antioxidant activity (Trolox equivalent= 1.33 mM). Ficus carica methanol extracts have antimicrobial and antioxidant...

A facile synthesis of novel 2-amino-1,2-dihydroisoquinoline-3(4H)-one and their amide derivatives (6a-o) through sydnone intermediate (3) was derived from tetrahydroisoquinoline-3-carboxylic acid (1) and various substituted phenyl acrylic acid derivatives (5a-o) in short reaction time with good yield. The structure of all novel synthesized compounds was established based on Mass, 1H NMR, 13C NMR, IR spectral data and Single crystal X-ray study (6e). All the synthesized compounds were evaluated for their antimicrobial and antioxidant...

Present investigation deals with the evaluation of the antimicrobial activity of extracts of Jatropha gossypifolia Linn., Sapium sebiferum (L.) Roxb., Kirganelia reticulata (Poir) Baill., Phyllanthus fraternus Webster and Pedilanthus tithymaloides (Linn.) Poit. against Escherichia coli, Proteus vulgaris, Staphylococcus aureus and Bacillus cereus and Trichophyton mentagrophytes and T. rubrum. The antibacterial activity was tested by the disc diffusion method and the antifungal (antidermatophytic) activity by the method of Abubacker et al. It was observed that only DMSO extracts of the leaves of K. reticulata and the flowers of P. tithymaloides inhibited the growth of P. vulgaris and S. aureus with MIC at 200 mg ml–1. The extracts did not inhibit the growth of T. mentagrophytes and T. rubrum. The phytochemical analysis of these extracts indicated that the tannin and saponin contents were highest in the leaves of K. reticulata (6.0 and 12.04 % respectively) whereas, the flavonoid and steroid and triterpenoid contents were highest in theflowers of P. tithymaloides (41.20 % and 46.74 %). The MIC values of extracted tannins...

Complexs of Fe, Cu and Zn have been prepared by reacting metal chloride\sulphate with p-hydroxyacetophenone thiosemicarbazone, p-fluoroacetophenone thiosemicarbazone, p-bromoacetophenone thiosemicarbazone as ligands and their complexes were screened for their IR, NMR, and antifungal and antibacterial studies. . Acetophenone thiosemicarbazone ligands were prepared by the reaction of substituted acetophenone with thiosemicarbazone in the presence of hot ethanol. All the transition-ligands 1:2 complexes have been isolated in the solid state, are stable in air, and characterized on the basis of their elemental and spectral data. They were found to be active against influenza, protozoa, small pox, and certain kinds of tumor. Their metal complexes were used, in various biological systems, polymers, dyes, anti-inflammatory, analgesic and anti-oxidative action. The Schiff bases and their metal complexes were used in various biological activities such as antimicrobial, antifungal, antiviral, insecticides, and antitumor...

The acute dental abscess is frequently underestimated in terms of its morbidity and mortality. The risk of potentially serious consequences arising from the spread of a dental abscess is still relevant today with many hospital admissions for dental sepsis. Acacia nilotica was commonly known in India as Babul has a wide range of medicinal uses. In the present study antibacterial activity of different parts of Acacia nilotica was studied to evaluate their potential for being used as natural antibacterial agent against various dental infections. The bioactivity Acacia nilotica was analyzed crude extracts of bark, leaves, and Pod of Acacia nilotica against five dental pathogens (Lactobacillus acidophilus, Streptococcus sanguinis, Streptococcus salivarius, Aggregatibacter actinomycetemcomitans) using agar diffusion technique and determine the minimum inhibitory concentration of each extract against the dental pathogen. The present study conducted to evaluate the highest anti dental infection property of different extract of Acacia nilotica. In this study the pod extract shows highest antibacterial potential followed by the bark extract and leaves...
