In this research ,total lipid ,fatty acids ,soap index and iodine index were determined by Soxhlt method,Gas chromatography and chemical methods in seed of several varieties of cucurbita,respectively.Then considering the result and using the multy variable statistical methods these varieties were studied and compared chemotaxonomically.Conclusionly four main of fatty acids, including,palmitic,stearic,oleic and linoleic acids,were observed in four studied plant. Range of oleic acid was between 75.98- 81.84% and linoleic acid was between 12.1 _ 16.5%.In addition another fatty acid ,myristic acid,(3.88%)was measured in kaghazi variety from cucurbita pepo, which is absent in other plants.In study of chemical characteristics of seed oil, soap index were measured by titermetry method and iodine.
