Antimicrobial activities of several parts of Pinus brutia, Juniperus oxycedrus, Abies cilicia, Cedrus libani and Pinus nigra

In this study, the antimicrobial activities of several parts of various tre es grown in the Kahramanmaras region of Turkey were investigated by the dis c diffusion method. Chloroform, acetone and methanol extracts of leaves, re sins, barks, cones and fruits of Pinus brutia Ten., Juniperus oxycedrus L,, Abies cilicia Ant. & Kotschy Carr,, Cedrus libani A. Rich. and Pinus nigra Am. were prepared and tested against Bacillus megaterium DSM 32, Bacillus subtilis IMG 22, Bacillus cereus FMC 19, Escherichia coli DM, Klebsiella pn eumoniae EMC 3, Enterobacter aerogenes CCM 2531, Staphylococcus aureus Cowa n 1, Mycobacterium smegmatis RUT, Proteus vulgaris FMC 1, Listeria monocyto genes Scoot A, Pseudomonas aeruginosa DSM 5007, Candida albicans CCM 314, C andida tropicalis MDC 86 and Penicillium italicum K. The results showed that antifungal effects were not observed for the whole extracts, E, coli was not inhibited by any of the plant extracts except by the chloroform and acetone extracts of the leaves of A. cilicia, which show ed inhibition zones of 16-18 mm, respectively, All the plant extracts used in this study inhibited the development of the other bacteria studied, When the results of this study were compared with an ampicillin standard, it tv as found that the microorganisms studied mere generally susceptible, interm ediate or resistant to the extracts of species when compared with the ampic illin standard. On the other hand, the acetone and methanol extracts of Jun iperus fruits were found to be quite resistant. Copyright (C) 1999 John Wil ey & Sons, Ltd.
