Abstract
The antimicrobial property of Taraxacum officinale plant extracts have been carried out by Agar Well Diffusion method. Five types of microbial strains viz. (Streptococcus mutans, Streptococcus pyogenes, Streptococcus pneumonia, Streptococcus aureus and Pseudomonas aeruginosa) have been used for the estimation of antimicrobial effect of Taraxacum officinale. The DCM, ethyl acetate, methanol and water extracts of stem, root and flower of Taraxacum officinale gave the varying values of IZD, on their application against the microorganisms with the safe conclusion on the fact that the solvents could extract the different bio-organics varying in number and antimicrobial potential(s). The concentration increase of the extracts resulted in the increase of IZD values resulting in the increase in the antimicrobial activities of the extracts. Among all the plant extracts, the methanolic extracts were found to bear the highest antimicrobial potential against the all bacterial strains, followed by the Ethyl acetate extracts of the plant. The DCM extracts were found to possess the antimicrobial potential in between ethyl acetate extracts and the water extracts. The water extracts were found to have little influence upon the growth of micro-organisms. Among the plant parts observed, roots were observed to be more effective in inhibiting the growth of micro-organisms followed by flower extracts. The stem extracts have a little effect upon the growth of micro-organisms.
Highlights
Plants are of most important sources of medicines since times immoral
Five types of microbial strains viz. (Streptococcus mutans, Streptococcus pyogenes, Streptococcus pneumonia, Streptococcus aureus, and Pseudomonas aeruginosa) have been used in order to know about the antimicrobial effect of T. officinale
The DCM, ethyl acetate, methanol and water extracts of stem, root and flower of T. officinale gave the varying values of Inhibition zone diameter (IZD) on their application against the microorganisms with the safe conclusion on the fact that the solvents could extract the different bio-organics varying in number and antimicrobial potential(s)
Summary
Large numbers of drugs are being isolated and extracted from plants. Wolbis et al [1] carried out an analysis in which they mentioned and isolated various polyphenolic compounds from T. officinale plant extracts thereby showing that the plant is rich in various antioxidants and can have a direct effect of these phytochemicals with health of an organism. The concerned plant is being consumed in the Kashmir valley from times immoral as source of vegetable and for the lactating mothers as a source of minerals especially calcium. Taking these above mentioned factors into mind the study was carried out to know the microbial properties of the plant. The reference plant was collected from the North region of Kashmir (J&K) district Kupwara
