RESUMO
The lipid content of Salicornia fruticosa [L.] grown in Egypt was studied. A series of hydrocarbons ranging from C[13]-C[31], in addition to cholesterol, stigmasterol and the triterpenoid alpha-amyrin were identified. The GLC of the fatty alcohol fraction revealed the presence of 8 fatty alcohols, also the analysis of the fatty acid fraction revealed the presence of 11 fatty acids in which palmitic acid [32.4%] represent the main component. The flavonoidal constituents isolated from the chloroform, ethyl acetate and butanol fractions of the aqueous alcoholic extract of S. fruticosa were identified as apigenin, isorhamnetin, isorhamnetin-3-O-galactoside, acacetin and apigenin-7-O-galactoside. The crude protein of the plant was found to be 14.75%. The analysis of the amino acids revealed the presence of 14 amino acids. The mucilage hydrolysate of the aerial parts of S. fruticosa was found to contain xylose, manose, galactose and glucose using PC. The radical scavenging effects of the extracts and isolated compounds on DPPH free radical were studied, n-butanol and ethyl acetate extracts showed strong antioxidant activity, also the isolated flavonoidal compounds showed high antioxidant activity compared to Trolox [standard antioxidant compound]. The different extracts and isolated compounds of the plant exhibited no cytotoxic activity against Ehrlich-ascitis carcinoma cell line at the tested concentrations
