Abstract Tunceli is a province that has different kind plants and large biodiversity and also there are more endemic and local endemic species. It has also consist of more medicinal and aromatic plants naturally grown. The essential oil from plants has more widely used for different purposes. The essential ois of wild-growing Allium tuncelianum from Munzur Valley in Turkey was obtained by hydrodistillation and analyzed by GC and GC-MS. In the oil of the Allium tuncelianum were characterized 1-propene 3,3- thiobis (21.2%), disulfide di-2-propenyl (12.9%), trisulfide di-2-propenyl (21.2%), diallyl tetrasulphide (17.35%) and linoleic acid ethyl ester (6.2%) as the main constituents. The light and scanning electron microscope results showed that the pollen grain Allium tuncelianum is monads, oblate (P/E= 1.39), monosulcate. The exine sculpturing is rugulate-perforate. The sulcus extends to the proximal side of pollen.
