\nMatricaria aurea<\/em> L. is considered the most available plant in the Syrian flora, and it has multi-popular uses. This was the motive to conduct this scientific study. The work focused on the plant ecology and its essential oil.
\nThe middle region of Syria had been chosen; mainly the provinces Homs and Hama, to conduct the work .The two provinces represent large area\u00a0\u00a0 of Syria and have different ecological locations.
\nThis work was carried out during 2008 \u2013 2009. Investigation\u00a0\u00a0 of ecogeographic survey shows that an enormous set-back had taken place within\u00a0 Matricaria aurea<\/em> L. concerning its natural habitats and the severs collection of the plant, in addition to land reform into farming system.
\nEight location have been selected. Plants samples were steam extracted in a shelf\u00a0 manner in a four replicates for each. The results showed that in both years the highest percentage of essential oil was at the site of Hamra\u00a0 at the pick of flowering stage .The amount of essential oil were 0.15% ,0.16 %\u00a0 respectively (ml \/ 100 g dry flowers ). The results also showed the role of the interaction between the soil and the climate on the percentage of oil\u00a0 in the different location.
\nStudying the content of the essential oil by the technique of GC\/MS revealed more than a hundred compounds where the Caryophyllene oxide showed to be the main compound representing between (11-42%).
\nEnvironmental study showed that the factor of humidity has the most important effect on the essential oil quantity.
\nThe results of the study of cultivation of Matricaria aurea<\/em> L. indicated that the best date for the cultivation of the plant is from January 15 until the first of February, as the appropriate depth for cultivation of the plant should not exceed 0.5 cm .<\/p>\n","protected":false},"excerpt":{"rendered":"
