Comparative study of the essential oils in leaf and stem of Zhumeria majdae at vegetative stage

The monotypic Iranian Zhumeria majdae (Lamiaceae), known locally by the name of Mohrekhosh, was recently described as the first member of a new genus (Zhumeria). It has a limited geographical rang in southern Iran at Hormozgan province. The leaves have been used for many years as a curative for stomachaches and an antiseptic. In this research, the constituents of essential oils of Zhumeria majdae leaves and stem in Geno mountain of Hormozgan province were analyzed via GC and GC/MS and compared together. The oil yield of the dried leaves and stem by hydrodistillation were 7.5 and 0.3 %, respectively (v/w). 22 and 19 compounds were identified. The major constituents were Linalool and Camphor, which they belong to first group. Wheras, compounds, like alpha-Pinene, Camphene, Limonene, Alpha-terpineol, Caryophyllene oxide and Myrcene belong to second group.
