Phyto-chemical Screeningof Seedsand Physicochemical Characterization of the Oil of Citrullus Colocynthis

Abstract

A sample of Citrullus colocynthis fruits were collected from Alamab Area South Khartoum state, the seeds were isolated after dryness of the fruits. Phytochemical screening of the seeds indicate that they contain of flavonoids, tannins, cumarins , sterol, triterpene, saponins and Alkaloids. The oil of Citrullus colocynthis was extracted from the seeds. The average yield was 20%. Physico-chemical characterization result show that the density of the oil was 0.9728 g/cm3, Iodine value was 94.68, Saponification value was 223.763, Acid value was 1.29, Peroxide value was trace and Ester value was 222.473.
