Preferred Abstract (Original): 
Background: In the recent years new technique s were applied for extraction and isolation of natu ra l  phytochemicals  from living organisms by using microwaves to assist extraction , decrease the time and  cost of  isolation methods in the same ti me these methods  must  gua rantee the highest yield from the plants. Objectives: this research aimed to evaluate two methods of volatile oils extraction, the microwave accelerated  distillation and hydrodistillation also to  find  the best source of Rue oil  Rut a graveolens  or Ruta chalepensis leaves.  In this  research , the effect of microwave power on the yields of volatile oils in  R . graveolens  and R . chalepensis is the first time proven in the literature. Method: Microwave accelerated distillation was applied f or the extraction of  volatile oil s from the leaves of  Ruta graveolens  and Ruta chalepensis . The microwav e assisted extraction method had been compared with  hydro distillation  conventional technique, in terms of extraction  yields , cost and time . Results: The volatile oils of the dried  Ruta graveolens collected from the Jerusalem  area  of Palestine were  recovered by microwave accelerated distillation  method with approximately  2.2 % yield  in  Ruta graveolens and  approximately 1.8% yield of the volatile oils in  Rut a chalepensis on a dry weight basis ,  in the same time the  yield was approximately 1.2% in  Ruta graveolens  while was 0.6% yield of the volatile oils in  Ruta chalepensis  by using hydrodistillation method. Conclusion:  The results show ed that  the  isolation of  the  volatile  oils from  R. graveolens  and R. chalepensis by  microwave assisted extraction is more efficient  in time cost and yield  rather than  hydrodistillation; also the  results showed that the best economical source for Rue oil is  R. graveolens for food,  cosmeceuticals and  pharmaceutical industries
