Extraction, and Physicochemical Characterization of Solanum dubium Seed Oil

Abstract

The aim of this study is to investigate the quantity of Solanum dubium seeds oil and study some physio-chemical properties of the extracted oil. The results show the oil yield was (50%), fatty acid composition was (75%), phytochemical screening of the seed powder show higher Alkaloids contents (+ + +), moderate Flavinoid composition (+ +), low tannin content (+) and free of Saponine, Cumarin, Steroids, and Anthraquinones. Investigation of the chemical properties show the Saponification value (131.835), Ester value (130.713), acid value was (1.122), mg/g and no Peroxides. The study of antimicrobial sensibility shows that Candida(16.5mm), Bacillus (15.5mm), Pseudomonas, Staphylococcus (15mm), and E. coli unaffected. GC-MS of the oil show that it is contain 9-12Octadacenoic acid (54.17%), Hexadecanoic acid (17.8)%, 9-Octadecenoic acid (15.82%), Methyl stearic acid (7.49%) as the major fatty acids (98%).
