Abstract: The extraction technology of total flavonoids from the leaves of Dendrocalamous latiflorus Munro was studied. The results showed that extraction time, extraction temperature, liquid-solid ratio and stirring rate had significant effect on yield. The optimal conditions were as follows:60%(volume fraction)ethanol,80℃ temperature, 25:1(mL:g) liquid-solid ratio,300 r/min stirring rate. After two times extraction and 2 h each time, the yield of total flavonoids was 1.06%.

Key words: Dendrocalamus latiflorus Munro, total flavonoids of bamboo leaves, extraction
