Phytochemical Screening and Antimicrobial Activity of Leaf Extracts of Zanthoxylum armatum against some Bacteria and Fungi DC: An Important Medicinal Plant

The medicinally active substance were isolated from dried leaves of Zanthoxylum armatum DC by using Soxhlet apparatus and identified by photochemical tests. The soxhlet extraction in powdered form was performed using Petroleum ether, chloroform, n-hexane, acetone, ethanol and methanol. The result indicated that alkaloids were present in methanol and ethanol extracts. Flavanoids were present in acetone, chloroform, methanol and ethanol extract, Carbohydrates were present in acetone, petroleum ether, methanol, ethanol and n-hexane extract. Proteins and triterpenoids were not present in any of the extracts. The most Pseudomonas aerugenosa while most resistant bacteria wasE. coli. Maximum zone of Staphylococcus aureusat 100 % concentration. Among fungal strains Aspergillus fumigateswas the most susceptible whileAspergillusniger, Candida albicans and Saccharomyces cereviseae are the resistant ones. n-hexane and acetone extract did not show any antimicrobial activity against all the tested organism. None of the extracts showed any inhibitory potential against bacteria E. coli and Candida albicans, Saccharomyces cereviseae and Aspergillus niger
