The comparison of the essential oils chemical composition in healthy and infected Bakraei with Candidatus phytoplasma aurantifolia in Rigan-Bam

In this investigation essential oil chemical composition of healthy and infected Bakraei with Candidatus Phytoplasma aurantifolia from Rigan-Bam area have been studied. The branches of flower and roots of this species were collected in spring 2014 and dried in shade (at room temperature) and subjected to volatile fraction were isolated by hydrodistillation using an all-glass clevenger-type apparatus. The analysis of the essential oils were performed by using GC-MS. In the aerial organs, 39 components of essential oil of healthy bakraei were identified including linalool-L (22.7%), n- octane (11.4%), E-caryophyllene (9.8%), citronellal (8.7%), limonene (5.3%), β-bisabolene (5.3%) while, 44 components were identified in the essential oil of infected bakraei with major components including linalool-L (14.0%), n-octane (12.4%), E-caryophyllene (11.5%), citronellal (7.4%), β-bisabolene (6.9%), α-sinensal (6.0%) and limonene (5.3%). In the essential oil of underground organs in healthy bakraei, 9 components (including major component: elemol (34.3%), geijerene (11.3%), n-decane (8.0%), dictamnol (7.5 %), pregeijerene (6.0%), β-eudesmol (5.2%)) and in infected bakraie 12 components (including major component: elemol (39.5%), geijerene (16.9%), dictamnol (7.8 %), pregeijerene (5.0%). The comparison of the essential oil chemical compositions was showed that α-sinensal compound as one of the major components in infected aerial organs does not exist in healthy bakraei. Also, n-dodecane, α-santalane and seselinee as identified partial components in underground organs do not find in it,s healthy type.
