摘要：
Multiple bioactive compounds including phenolics, triterpene acids, cyclic nucleotides, VC, α-tocopherol and β-carotene contents were determined by HPLC. In the meanwhile, the antioxidant activity of jujube extracts and the correlation between antioxidant activity and antioxidants were also discussed. The results showed that there was significant difference on the multiple bioactive compounds contents among various cultivars jujube. The total phenolics, total flavonoids, individual phenolic compounds (vanillic acid, caffeic acid, syringic acid, epicatechin, catechin, rutin) contents of 'muzao' were significantly higher than these of the rest jujube. The total phenolics content was significantly correlated with the FRAP value and scanvenging ABTS·+ ability. In addition, the syringic acid content was significantly correlated with scanvenging ·DPPH ability the rest of individual phenolics showed no significant correlation with the antioxidant activity of jujube fruits. The α-tocophero, β-carotene contents and cAMP contents of 'hamidazao' was significantly higher than these of the other five of jujube and the cGMP level of 'jinsixiaozao' was significantly higher than that of the rest jujube. With regard to triterpene acids, all jujube fruit except for 'lizao', the betulinic acid was the predominant triterpene acid followed by oleanolic acid and ursolic acid. © 2017, Editorial Office of Journal of CIFST.
