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%).
