Essential oil composition and secretory structurs of Chaerophyllum macropodum Boiss

The genus of Chaerophyllum macropodum belongs to Umbelliferae family which used as spice. Alsoin Iran and Turkey it has been used for cheese production. In addition, it is traditionally believed by local people that this plant has antibacterial activity. C. macropodum were collected from northwest mountains of Aleshtar in Lorestan province, Iran. Collected plant materials were dried in shade and were hydrodistillated using a clevenger apparatus. The oil was analyzed by capillary GC and GC/MS. The anatomical studies were carried out using distaining method with brown bismark and methyl green. GC and GC/MS analysis of the essential oil resulted in the identification of 20 compounds, representing the 97.6% the total oil. Major constituents of the oil were myristicin (23.2%), p-cymene (16.7%), trans-ocimene (10.2%), sabinene (8.8%), cis-ocimene (7.3%) and spathulenol (6.1%). The anatomical studies showed that, secretory canals were found in differend regions of stem, especially in the near of collanchyma tissues.
