The main aim of this study is to analyze antioxidant properties of Polygonatum odoratum fermented with bacteria, fungi and yeast. Antioxidant activities (1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging, hydroxyl radical scavenging, and anti-lipid peroxidation abilities) were assessed in samples of flavones isolated from fermented P. odoratum (Mill.) druce samples. Fermentations using Lactobacillus, yeast and Aspergillus were investigated. Results showed that the antioxidant ability of Polygonatum odoratum flavones was decreased by the fermentation of Lactobacillus and yeast. Aspergillus niger fermentation improved the antioxidant ability of P. odoratum flavones. In this study, effective antioxidant activity was achieved in flavones fermented with Aspergillus niger than yeast and Lactobacillus species.
