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 extracts 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.

This research was carried out to determine the quantity of essential oil extracted from myrtle Myrtus communis L leaves, by hydro distillation, and to identify the major and minor components, besides to determine its quantities in the essential oil by Gas Chromatography-Mass Spectrometry GC-MS. The samples were collected on November 2013 from eight different climatic locations (Aleppo, Zarzour, Alzenea, Katra AL-Rayhan, Al- Rayhana, Kasab, Mashta al-Holou and Mosiaf). The quantity and composition of the essential oil were estimated on the basis of the leaves dry weight. Oil quantity varied between the studied genotypes from different locations, which range from 0.46 to 0.55 ml, with non-significant differences. Eighteen compounds were identified in myrtle essential oil, and there were significant differences in 13 compounds. 1,8-Cineole performed the highest rate (18.85%) compared with other components, followed by α-Pinene (16.93%). While the lowest percentage was (0.31%) of Myrcene. The
Activity of Ziziphora tenuior L. leaves organic extracts against four pathogenic bacteria, which were isolated from clinical samples and prepared from Al-Assad hospital laboratory in Lattakia, were tested by disc diffusion method through 2014. Res ults showed that Ziziphora tenuior L. leaves extracts have antibacterial activity against all Gram positive and negative bacteria. Inhibition zones were recorded between 9mm against Pseudomonas aeruginosa and 44mm against Staphylococcus aureus at concentration of 200mg/ml for the methanolic extract. Whereas the inhibition zones for the ethanolic extract were recorded between 7mm at concentration of 40mg/ml against Streptococcus sp. and 34mm at concentration of 200mg/ml against Staphylococcus aureus. These results represent the importance of Ziziphora tenuior L. as a source of natural substances counteraction of pathogenic bacteria.
Single nodes and axillary buds excised from adult trees of Myrtle (Myrtus communis L.) grown in the field under natural conditions at Damascus countryside (Ain Elfiegh) were used as primary explants, which were surfacedisinfected by 70% Ethanol an d Clorox containing 5.25 % Sodium Hypoclorite with a drop of Tween 20 for different periods and concentrations before being placed onto MS basal medium. Established cultures were then transferred onto MS basal medium containing a combination of growth regulators at different concentrations (BA at 2.22 and 4.44 μM) each with NAA at 0.54, 1.62, 5.4 μM or 1.47 μM IBA with GA3 at 0.58 μM for all tratments. Multiplication rate of 12.8-fold was achieved every 4 weeks on MS medium supplemented with 4.44 μM BA with 1.47 μM IBA and GA3 at 0.58 μM.
Olive trees are grown in many regions of Syria, especially in wet regions where the olive knot disease (Pseudomonas savastanoi pv.savastanoi ) prevails .Symptoms similar to those found on olive trees have been observed on myrtle shrubs (Myrtus com munis) growing naturally in some olive-grown regions. This study aimed at identifying the pathogen isolated from myrtle plant, and testing the pathogenicity of these isolates on olive trees. Morphological, biochemical and serological tests of bacteria isolated from myrtle showed similarity to those from olive and other hosts. Pathogenicity tests showed that the myrtle isolates were pathogenic on both myrtle and olive trees. Myrtle could be considered as a source of inoculum for the olive knot disease.
Due to the economical and medical importance of the Melilotus plant and the wide distribution of this plant in the Syria environment, it was of necessity to study the the composition of organic matter extracted from the leaves of this plant. The M elilotus Officinal organic matter was extracted and purified their where were studied by GC-Maas spectrometry. The organic matter was obtained by Soxhlet extractor and by solvent n-Hexane. Components have been found which was about (99.91%) from the total of Essential Oil. The major components were extracted by Soxhlet extractor and the following components were determined : n-Docosane(39.82%) , Hydrocoumarin(15.39%) , Methyl 3-(2-hydroxyphenyl)propionate(14.29%). The major components were determined by solvent n-Hexane: 1,2-Benzenedicarboxylic acid(17.77%) , 9,12,15-octadecatrienoic acid(12.85%) The effects of the extracted aromatic oil from the leaves of Melilotus plant on some of Pathogenic Microorganisms were studied.
