Abstract:
An ultrasonic method for the extraction of total flavonoids from Ligustrum Vicaryi Hort.was investigated and optimized.Using single factor and L9(34)orthogonal design,the effects of ethanol concentrations,ultrasonic time,ultrasonic power and extraction temperature were considered.The impact will activate by ethanol concentrations,ultrasonic time,ultrasonic power and extraction temperature.The optimum extracting conditions of total flavonoids are:mesh number 40,extraction time 75 min,extraction temperature 50 ℃,ultrasonic power 400 W and ethanol concentrations 65%.Under these conditions the yield of total flavonoids can reach the highest.
