DETERMINATION OF TANNIN CONTENT AND ANTIBACTERIAL ACTIVITY OF CHROMOLAENA ODORATA L.
Keywords:
Chromolaena odorata L., Folin-ciocalteu, tannins, TLC bioautographyAbstract
Aims and objectives: To ascertain the antibacterial capability using TLC-bioautography and the tannin content using the UV-Vis spectrophotometric method in the ethanol extract of kopasanda (Chromolaena odorata L.) leaves.
Methods: Tannins quantitatively utilizing the UV-Vis spectrophotometric technique using the folin ciocalteu reagent at a wavelength of up to 687 nm. Antibacterial potential against gastrointestinal infection-causing bacteria (Salmonella typhi, Vibrio cholerae, Escherichia coli, and Shigella dysentriae) is assessed using TLC-bioautography technique.
Results: The tannin content of the ethanol extract of kopasanda leaves (Chromolaena odorata L.) is 41.9064±0.26 mgTAE/g extract. Escherichia coli, Shigella dysentriae, Salmonella typhi, and Vibrio cholerae, respectively, create inhibitory zones in the antibacterial potential test that yields 7, 8, 8, and 7 stains. Tannins, flavonoids, alkaloids, and saponins are believed to be among the chemicals found in the TLC results obtained with stain spraying reagents 1, 3, 5, and 4, respectively.
Conclusions: The average tannin concentration of the ethanol extract of kopasanda leaves (Chromolaena odorata L.) is 41.9064±0.26 mgTAE/g extract, and it has antibacterial properties against germs that cause gastrointestinal illnesses.
