Four flavonol glycosides and one flavonol were separated and collected from myrica rubra leaf using reversed-phase high performance liquid chromatography with RP-C18 column as stationary phase and methanol-water-formic acid as mobile phase. The chemical structure of five flavonoids in myrica rubra leaf was identified by spectral analysis and their content was determined by reference to internal standard anthracene. Their antioxidant activity was determined in a rancidity analyzer and results showed that ...
