The effect of some ecological factors on the essential oil of Teucrium polium L.

Aim and Background. Teucrium polium L. belongs to the genus of Teucrium and Labiatae family. It has been used in folk medicine to treat some diseases. The aim of this research was investigation some effective ecological factors on the essential oils of Teucrium polium in different habitats. Material and Methods. The flowering aerial parts of Teucrium polium were collected, dried and obtained from 9 habitats in Mazandaran province. Of course the habitats were named G1-G9 that included 3 classified heights. Then the essential oils of this plant were analyzed by GC and GC-MS aparatus. This investigatation was done based on a complete randomized block design with 3 replications by using of SPSS statistic software. Results. There was a significant correlation between height, heat and moisture with α-Pinene, β-Pinene, Limonene, α-Copaene and the yield of the essence. The rain had a significant correlation with Sabinene. Among the elements of the soil there was only a significant correlation between the electerical conduction with α-Pinene, Limonene and E-β-Farnesene. Moreover a significant correlation was observed between the solution Sodium and Magnesium of the soil with Limonene. Conclusion. The lowest classified height was known as the best habitat because of quality of essence.
