[Studying of Biological Diversity of Some of LamiaceaeFamily plants (Zoufa and Thyme)in the Syrian Seaside]

The Thyme and Zoufa (hyssop) are two wild plant naturally present in the Syrian Seaside at varying altitudes up to more than 1000 m above sea level, they are considered two important components of biological diversity of wild plants in the Syrian flora. Samples were taken from seven sites (Safita - Beit Sheikh Younis, Khirbet Al-Mezah – Albirdanie, Sheikh Badr – Aljalsat, Banias – Shibani, Qadmous – Alhatria, Qardahah - Deir Hanna, Albhloulih - Beit Alia) Then conducted a study of the most important specifications morphological a plant height - Number of branches on the plant - branch length - number of leaves on the branch - the distances between the nodes and the number of flowers in the inflorescence flowering and then been working on extracting the essential oil of plants by distilling 200 g of dry leaves from each site to obtain the essential oil and we could not get Zoufa oil despite repeated several times in the experiments when they were getting an adequate amount of thyme oil . Statistical analysis of the morphological findings showed there were significant differences between the plants in each of the adjective plant height - the number of branches on the plant - branch length - number of leaves on the branch, did not show any significant differences in the distances between nodes recipe in thyme and Zoufa .While significant 59 differences appeared in the number of flowers in the recipe floral inflorescence of thyme and did not appear in the Zoufa. Gas Chromatography – Mass Spectrometry technique (GC-MS) was used for the determination of essential oil content of Thymol, Carvacrol and Pinene compounds. The results of chemical analysis showed that Thymol percentage ranged between 1.28 and 7.80 % and that of Carvacrol ranged between 75.32 and 83.27 %, while Pinene content ranged between 11.86 and 22.58%. Statistical analysis showed significant differences between the compounds contents studied in the seven sites. The percentages of Thymol were as Following Banias – Shibani Albirdanie Aljalsat Alhatria Beit Sheikh Younis
