Allelopathic Effect of the Liquid Extract of Parthenium hysterophorus on Microorganism

Dipak Kumar Kanaujiya, Neha Ansari, Saurabh Kant Dubey, Komal Chaudhary, Kesav Kishore


Basically in this work study of allelopathic effect of liquid extract of any weed on microorganism like Escherichia coli, Pseudomonas aeruginosa, Bacillus subtillis, Staphylococcus aureus, Parthenium hysterophorus plants were used for the isolation of liquid and oil extraction, because parthenium has a wide variety of medicinal and adverse effect over microorganism. Basically P. hysterophorous shows allelopathic effect over various crops and some time increases production rate as well as reduces the growth. It was observed that the organic solvent increased the activity of liquid extract of the potent isolates by many times. The best activity of liquid extract in organic solvent, and the liquid extract (distilled water and ethanolic) gives various diameter zones of inhibition in spread plate by well-diffusion methods, and later this liquid extract with the organic solvent Ethanol and acetone gives more valuable zone of inhibition in cultured colonies and we have seen comparative effect of antibiotics, liquid, ethanolic and so this study is helpful for herbal drug formulation and antibiotics as well as vaccine formulation.


Herbal drug formulation, Allelopathic, Liquid extract, Well diffusion.
