The paper studied the extracting of flavonoids in the stem of Dracaena cochinchinensis with microwave assisted extraction. The single factor and orthogonal designmethods L9（3^4） were applied for the optimal technological conditions ：50℃ ,90% ethyl alcohol, 1： 10,420 W,8 min. Under the optimized conditions, the extraction percent of total flavonoids was about 1.20% from the stem of Dracaena cochinchinensis .
