Total phenolic contents,total flavonoid contents,procyanidin contents,DPPH+ scavenging capability and total antioxidant capability were used to evaluate the composition of phenolic compounds and their antioxidant activity in jujube marmalade.The results showed that phenolic acids are the main phenolic compounds in jujube marmalade,and they are mainly presented in esterified form.Compared with jujube,the total phenolic contents and procyanidin contents in jujube marmalade were decreased,but total flavonoid contents were increased and antioxidant activity went up.This indicates that the jujube marmalade has strong antioxidant activity.
