The Present Study found out the extraction the oil of Cucurbita maxima and determination the ratio of it in seeds , leaves , hypocotyle stems and in callus of this parts like percentage. This study singled out Fatty acids like palmitic acid , stearic acid, oleic acid, linoleic acid, and also Singled out new three Fatty acids like, Myristic acid, arachidic acid and Lauric acid first time in this plant besides the qualitative diagnosis of cucurbitacin and defining its isomers Cuc E, Cuc B ,Cuc I, and Cuc L by using thin layer chromatoghraphy (TLC).
