The main aim of this study was to find a new natural, non toxic, effective antibiotic from plant extract. In the present study, Solanum torvum (Sundakai) was selected. The antibacterial activity of different extracts of Solanum torvum (Sundakai) fruit coat was studied in vitro against human pathogenic strains. The Water Extract (WE) and Ethanol Water Extract (EWE) was found to be effective against all bacterial strains and inhibition is comparable to that of commercial antibiotics, choramphenicol and streptomycin. Initial screening of antibacterial activity was done by disc diffusion method in Nutrient agar medium. Minimum inhibition concentration was done serial dilution method. The MIC values of the Water Extract (WE), Ethanol Water Extract (EWE) and Ethanol Extract (EE) ranged from 9.6 to 19.2 μg mL-1. It was observed that there was a correlation between the amounts of polyphenols and flavonoids content and effective antibacterial activities of the inhibited extracts. These results indicate that Sundakai coat may be yet an another source of natural antibiotic. Further, this study reaffirms the ethanomedicinal property of S. torvum plant.

I will be very grateful if I can get in touch with the authors. I am an aspiring Phd student and will be working on micropropagation of S. torvum. I need more information about the plant
