Abstract

The method and influencing factors of total flavonoids extraction in Juglandis Mandshuricae Cortex were studied systematically.Taking the total flavonoids content as index,the effect of extraction method including routine extraction,ultrasonic extraction,reflux extraction and Soxhlet extraction and kind of solvent,concentration and temperature on extraction rate were investigated.The results showed that the best extraction method was ultrasonic extraction.The extraction rate was the highest when the concentration of ethanol was 60% and the temperature was 60℃.

Key words： Juglans mandshurica Cortex; total flavonoids; extraction method
