Abstract : The work described in this Thesis has been undertaken with the object of contributing further studies of some flowering plants wild in Al-Baha area in Kingdom of Saudi Arabia. Twelve plants from different families were chosen according their valuable medicinal importance and many of them used as edible plants. The volatile oils from the plant samples were isolated by hydrodistillation. The identification of volatile oils constituents were carried out by GC/MS analysis. The phytochemical screening of the natural constituents of the selected plants were done. In addition to identify the hydrocarbons and fatty acids by GLC analysis and study the distribution of elements in all plant samples. The aerial parts of the two plants (Achillea biebersteinii and Dodonaea viscosa) were selected for further phytochemical examinations. From ethyl acetate of Achillea biebersteinii, three derivatives of 3- methoxy flavone aglycones SA1, SA4 and SA5 were isolated, beside two germacranolide sesquiterpenes SA2 and SA3. All the isolated compounds were identified for the first time from Achillea biebersteinii. On the other hand, Toluene and ethyl acetate extracts of Dodonaea viscosa gave six of flavone aglycones SD1-SD6. On the other hand, methanolic extract gave one flavone glycoside SD7. Throughout the investigation different chromatographic techniques such as, TLC, PC, CC, GLC and GC/ MS have been adapted and useful information were obtained on the utilization of modern spectroscopic techniques such as, UV, MS, 1H and 13C NMR techniques.
