Inhibition activity of extracts (acetone, ethanol, water) parts of the (Myrtus
communis L.) (root, stem, leaves, fruits) with concentrations (25,50,75,100%)
was carried out against growth of Gr- and Gr+ bacteria which were isolated and
identified
from the pathogenic specimens of The University Children's Hospital
bacterial laboratory in Damascus, using agar well diffusion method on Mueller
– Hinton medium.
During the last twenty years there was an increased interest to large extent in
crowing up the fruitful trees all over the world. That is a natural result of knowing its high
feeding value beside its being good source for income. Due to its economical importance,
there was variety of searches and studies which approached its farming.
to investigate the effect of Myrtus communis L ethanolic extract in
streptozotocine-induced diabetic rats.
Bioeffect of some Syrian Myrtus communis L. leaves extracts in growth of some pathogenic microorganisms, which were isolated from Al-Assad hospital laboratory in Lattakia, was tested by disc diffusion method. Results showed that cold and hot water ex
tracts have antibacterial activity against all Gram positive and negative bacteria, and pathogenic Candida albicans except Klebsiella pneumoniae. All organic extracts have antibacterial activity against Proteus vulgaris, Entrococcus faecium, Staphylococcus aureus and Staphylococcus albus.
Pseudomonas aeruginosa and Pseudomonas fluorescens were affected by most of the organic extracts, and the most bioactivity was by methanol extract, and all inhibition zones of extracts were bigger than inhibition zones by control
antibiotics. Serratia marcescens and Acinetobacter calcoaceticus were affected by methanol (with highest inhibition zone 37.33 and 27.33 mm respectively), ethanol, acetone and ethyl acetate extracts, but resistant to the others. Klebsiella pneumoniae affected by ethanol extract only with inhibition zone 20.33 mm.
Results of bioactivity according to a various solvents used in this study demonstrate that Syrian Myrtus communis L. leaves extracts have antimicrobial activity, so expected to be potential sources of natural antibacterial and antifungal products against some pathogenic bacteria and fungi in the future.
