Abstract

The antimicrobial activities of the ethyl acetate, acetone and methanol extract of 12 plant species were studied. The extract of Capsicum annuum (red pepper) (fruit) Zingiber officinale (ginger) (root), Cuminum cyminum (cumin), Alpinia ficinarum (galingale), Coriandrum sativum (coriander), Cinnamomun zeylanicum Nees (cinnamomun), Origanum onites L. (thyme), Folium sennae (senna), Eugenia caryophyllata (cloves), Flos tiliae (lime), Folium menthae crispae (peppermint) and Piper nigrum (blackpepper) were tested in vitro against 2 fungi and 8 bacterial species by the disc diffusion method. Klebsiella pneumonia 13883, Bacillus megaterium NRS, Pseudomonas aeroginosa ATCC 27859, Staphylococcus aureus 6538 P, Escherichia coli ATCC 8739, Enterobacter cloaca ATCC 13047, Corynebacterium xerosis UC 9165, Streptococcus faecalis DC 74, Kluyveromyces marxianus, Rhodotorula rubra were used in this investigation. The results indicated that extracts of different spices has shown antibacterial activity in the range of 7-24 mm? 30?l^-1 inhibition zone Eugenia caryophyllata (clove), 7-20 mm 30?l^-1 inhibition zone Capsicum annum (red pepper) and Cinnamomun zeylanicum (cinnamon) bark, 7-18 mm 30?l^-1 inhibition zone Folium sennae (senna) leaves, 7-16 mm 30 ?l^-1 inhibition zone Zingiber officinale (ginger) root, 7-15? mm 30?l^-1 inhibition zone Cuminum cyminum (cumin) seed, 7-14 mm 30 ?l^-1 inhibition zone Folium menthae crispae (peppermint), Origanum onites (thyme) leaves and Alpinia ficinarum (galingale) root, 7-12 mm 30 ?l^-1 inhibiton zone Piper nigrum (blackpepper), 7-11 mm? 30?l^-1 inhibition zone Flos tiliae (lime) leaves, 7-8 mm 30?l^-1 inhibition zone Coriandrum sativum (coriander) to the microorganisms tested.
