The medicinal plants represent a massive reservoir of probable microbial compounds that could be useful as a substitute to synthetic microbicides as well as are being used to develop drugs. In the present study, the powder extracts of Ricinus communis L. (Euphorbiaceae) were tested for their antioxidant activity by radical scavenging activity using 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) method and antibacterial acitivity against different bacteria i.e. Shigella flexneri, Staphylococcus aureus, Salmonella typhi, Pseudomonas aeruginosa, Klebsiella pneumonia, Proteus vulgaris, Enterobacter aerogenes, Aspergillus niger, Candida albicans, Trichophyton rubrum by disc diffusion method. Also, Phytochemical screening of methanolic extracts of Ricinus communis have been screened. Further, the antioxidant activity shows moderate to potent antioxidant activity, with the ED50 value i.e. 0.838 μg/ml. When screening for antimicrobial activity, the results were expressed in terms of the diameter of the inhibition zone: The maximum efficacy of methanolic extract was showed against Enterobacter and Aspergillus niger.Keywords

The present study has been designed with the objective to examine the methanol extract of Tectona grandis L. leaves (family Verbenaceae). In order to investigate its antimicrobial potential against strains of Shigella flexneri, Staphylococcus aureus, Salmonella typhi, Pseudomonas aeruginosa, Klebsiella pneumonia, Proteus vulgaris, Enterobacter aerogenes, Aspergillus niger, Candida albicans, Trichophyton rubrum. The methanolic extract was found to be the most effective and showed antimicrobial activity against the organisms tested. The zone of inhibition (mm) at various concentrations of methanolic extract of Tectona grandis L. was found in the range 50mg/20disc - 200mg/20disc on tested all the test organisms. The antimicrobial activity was more significant against Salmonella typhi i.e. 21.33 mm zonetion. The study revealed the methanol extract of Tectona grandis L. leaves against microbes.Keywords

Solanum surattense and Solanum nigrum belongs to the family Solanaceae and in general commonly circulated species. Ethanomedicinally these genus are noteworthy as well as traditionally known as Yellow- barried-nightshade and Makoy in ayurvedic classification of medication. The goal of the SWOT was to scrutinize the antioxidant activity of methanolic extract of Solanum surattense and Solanum nigrum by dissimilar in-vitro methods. Extract from two plants; Solanum surattense and Solanum nigrum were tested for antioxidant activity using 2,2-Diphenyl-1-picrylhydrazyl (DPPH). Free radical assays like as iron chelating, total antioxidant activity. It was experiential that the methanolic extract of Solanum surattense and Solanum nigrum successfully scavenged free radical activity that that of other extracts. Those antioxidant activities were compared to paradigm antioxidants such as ascorbate as well as EDTA. Our conclusion endow with the evidence that the rudimentary methanolic extract of Solanum surattense and Solanum nigrum are the probable cause of natural antioxidant, along with this vindicated its uses in folkloric medicines.

Antimicrobial activity of the extracts of Solanum xanthocarpum against bacteria and fungus was evaluated. Plant extracts of S. xanthocarpum were prepared in distilled water and in organic solvents, petroleum ether, chloroform, benzene, ethyl acetate and ethanol. Disc diffusion method technique was used to assess the antimicrobial activity of various extracts against Shigella flexneri, Staphylococcus aureus, Salmonella typhi, Pseudomonas aeruginosa, Klebsiella pneumonia, Proteus vulgaris, Enterobacter aerogenes, Aspergillus niger , Candida albicans, Trichophyton rubrum. The diameter of zone of inhibition was taken as an indicator of antimicrobial effect. Except aqueous extracts of S. xanthocarpum, extracts prepared in organic solvents showed antimicrobial activity against the test organisms. Methanol extract showed the best activity against all test microorganisms than other solvent extracts. The maximum efficacy of methanol extract A4 (200mg concentration) was against Staphylococcus aureus (I.Z.-23mm) was screened. Thus, S. xanthocarpum could be considered as a potential source of natural antimicrobials.
