Abstract:
Taking leaves of Indocalamus latifolius as experimental material，the effect of the ethanol concentration,solid-liquid ratio,extraction time on the yield of total flavonoids were studied by the single factor experiments and orthogonal experiments,and the extraction technology was optimized.The results showed that the optimized extraction process of ethanol refluxing method,the extraction solvent was 85% ethanol，material/liquid ratio was 1∶20 g/mL，extracting time was 50 min.The optimized extraction process of ethanol ultrasonic method：the extraction solvent was 85% ethanol，material/liquid ratio was 1∶30 g/mL，extracting time was 35 min.Under the optimum process conditions,the yield of total flavonoids from leaves of indocalamus by ethanol refluxing method was 2.66%，the yield by ethanol ultrasonic method was 1.59%，the ethanol refluxing method was more suitable for the extraction of flavonoids.
