Comparative Study on the Antioxidant Activity of Monascus Yellow Pigments From Two Different Types of Hongqu-Functional Qu and Coloring Qu.

ABSTRACT: This study is the first to investigate the difference in the composition of Monascus azaphilone pigments (MonAzPs) between functional Qu (FQ) and coloring Qu (CQ) and analyze their relationships with antioxidant activity. The composition of key active components and antioxidant activity of the ethanol extracts of FQ and CQ were analyzed by Uv-vis, HPLC, and chemical antioxidant tests. The composition of MonAzPs of the ethanol extracts was further analyzed by HPLC-MS. Seven Monascus yellow pigments (MYPs) with high abundance were successfully purified for the antioxidation evaluation in vitro and in the cell. Correlation analysis between the metabolites and the antioxidant activity of Hongqu indicated that MonAzPs might play an essential role in the antioxidant a
