Abstract

Ziziphus jujubapulps are very much appreciated by the inhabitants and have beenrecently exported. This article reports on the chemical composition (amino acids,polyphenols and sugars) of the pulps of fourZ. jujubaecotypes (Choutrana, Mahdia,Mahres and Sfax). The major amino acids identified were proline, aspartic acid andglutamic acid. Among these, proline was the most abundant amino acid (17.4 mol).Considerable differences in total phenolic contents (15.85 mg/L) were found.Predominant phenols identified by using HPLC were rutin (1.09 mg/L) and chlorogenicacid (2.57 mg/100 g). Sugars isolated fromZiziphuspulps were found at a rate of43.52%. Using HPLC method, three sugars from the pulp extract were identified:glucose, galactose and sucrose. The Mahdia ecotype was the richest in these sugarswith 0.45, 136.51 and 113.28 mg/L, respectively.
