This study was carried to investigate the volatile oil content of (basil - rosemary - marjoram - rose) plants grown inrndifferent regions at Taif Governorate. Moreover, the main components of volatile oil as well as, changes in itsrncompositions were also investigated as a result of changing the collection regions. The samples for volatile oilrnextraction were collected from several regions and volatile oil was extracted and consequently its percentages wererncalculated. The volatile oil composition was occurred by using GC-MS and the main components of volatile oilrnfrom different regions were compared. The results of this study showed that the volatile oil percentage was changedrnamong the collection samples in all studied plants. Moreover, the percentages of the main components of volatile oilrnwere also differed as results of changing the geographical regions. Studying the environmental conditions of thernlocation which aromatic plants will be cultivated is recommended according to our study.
