Journal Title: The Journal of Phytopharmacology - Year 2016, Vol 5, Issue 4
Abstract
The fruit of Syzygium aromaticum is an important medicinal plant was subjected to phytochemical screening and antimicrobial effect of methanol, ethyl acetate and acetone extracts. Antimicrobial activity was analyzed by agar well diffusion method against gram positive and gram negative bacteria. The phytochemical analysis carried out revealed the presence of alkaloids, coumarins, catechins, flavanoids, phenols, saponins, terpenoids, tannins and steroids in various solvent extracts. Methanol extract of S. aromaticum showed good antimicrobial activity against Bacillus subtilis, Pseudomonas aeruginosa and Staohylococcus aureus. It has been showed that the methanol extracts had wider range of activity on these organisms than the acetone and ethyl acetate extracts, which indicates that the methanol extracts of selected plants may contain the active components. The use of plant extracts with known antimicrobial properties can be of great significance in therapeutic treatments.
