The comparison of constituents of leaf essense oils in endemic and medicinal Zhumeria majdae Rech.f. & Wendelbo at different stages

The monotypic Iranian Zhumeria majdae (Lamiaceae),known locally by the name of Mourekhosh,was recently described as the first member of a new genus(Zhumeria)lt has a limited geographical rang in south of 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 essence oils of Zhumeria majdae leaves before flowering and at the end of flowering in Geno mountain of Hormozgan province were analyzed via GC and GC/MS and compared together. The oil yield of the dried leaves by hydrodistillation at two stage were7.5 and 9.3%, respectively (v/w). At the essence oils before flowering and at the end of flowering stages,22 and 16 compounds accounting for 99.9% of the oil, were identified.Camphenol,one of the end of flowering stage compounds, at the before flowering stage,and five compounds of the before of flowering stage (Alpha-phellandrene, p-cymeme,cis-Linalool oxide, trans-Linalool oxide, Neral and Caryophyllene oxide) have not been shown at the essence oil of flowering stage. The major constituents were Linalool (35.6-39.4) and Camphor (39.8-42.1), that they belong to the first group. Whereas, four compounds,Camphene (3.51-4.13), Limonene (2.94-3.47), Alpha-terpineol (2.83-2.93) and Myrcene (1.77-2.16) belong to the second group. 17 other compounds, are as minor components in the essence oil at different stages.
