Abstract:
In this article, the purified anthocyanins from Lonicera edulis Turcz was acylated. The UV absorption spectrum and infrared spectrum showed that the sample had been acylated successfully. To research the antioxidant activity of anthocyanin derivatives, the following experiments were carried out, including the scavenging effects on DPPH?,?OH, O2?and H2O2. anti-lipid peroxidation and total antioxidant and reduction capacities with Vc and no acylated sample as the control group. The results showed that, anthocyanin derivatives exhibited antioxidant abilities in a dose dependent manner. The total antioxidant capacity was stronger than Vc and the scavenging effects on ?OH, O2?and H2O2 were close to Vc, but the reduction capacity, anti-lipid peroxidation and the scavenging effect on DPPH? were weaker than Vc.
