Abstract: Flavonoids in leaves of Prunus virginiana was determined by spectrometric. The analytical result showed that the average content of flavonoids in leaves of Prunus virginiana was 0.875%. The optimum extracting conditions were: alcohol density 60%, extract time 2.5h, extract temperature 60℃ and solid-liquid ratio 1g: 30ml.

Key words: Prunus virginiana, total flavonoids, spectrometric method, extract
