Abstract: The scavenging effects of Litchi fruit pulp and Longan fruit pulp on O2-• were studied by using ammoniumpersulfate /N,N,N’,N’ tetramethyl ethylene diamine system (AP-TEMED) method. The cleaning capability of polysaccharidesof Euphoria Longan (Lour.) Steud and the Litchi Chinensis Sonn for oxygen free radicals was determined. The results showed thattwo kinds of fruit scavenging effect on activated oxygen were rather strong, and the result of Longan was better that Litchi. Theability of the polysaccharides of Litchi to weeded out the oxygen radical was us with the amount of polysaccharide but Longanhad not the similar ability.

Key words: Litchi fruit pulp, Longan fruit pulp, Polysaccharides of the Euphoria Longan(Lour)Steud and the Litchi chinensis Sonn, activated oxygen, scavenging
