Abstract
The recycling of agro-industrial bio-wastes of most vegetable residues into value-added products has been highly encouraged. High-value naturally occurring compounds can be found in sugar beet pulps. Comprehensive GC/MS analysis of the volatile compounds of petroleum ether (60-80oC) and methylene chloride fractions of sugar beet pulps has led to the identification of thirty eight volatile secondary metabolites of biological interests belonging to different classes such as acetogenins (Fat derivatives), sesquiterpenes, sterols and shikimate derivatives (phenolic constituents). Twenty-two compounds were identified from petroleum ether (60-80oC) extract, the most predominant constituents were n-hexadecanoic acid (42.79 %),  (Z,Z)-9,12-octadecadienoic acid (21.94%), hexadecanoic acid, methyl ester (6.67%), (E)-8-octadecenoic acid methyl ester (5.40%), (Z, Z)- 9,12-octadecadienoic acid methyl ester (5.02%) and (3β, 5α)-stigmasta-7,16-dien-3-ol (1.53%). Methylene chloride fraction afforded twenty three compounds and the more predominant constituents were 2-hydroxy-1-(hydroxymethyl) hexadecanoic acid ethyl ester (11.20 %), (Z) 9- octadecenal (7.08%), hexadecanoic acid, methyl ester (5.17%), 4-((1E)-3-hydroxy-1-propenyl)-2-methoxyphenol (4.37%), n-hexadecanoic acid (3.23 %), (Z,Z)-9,12-octadecadienoic acid methyl ester (3.04 %), (Z)-9-octadecenoic acid methyl ester (2.95%) and (3β, 24S) stigmast-5-en-3-ol (2.00 %).
