Abstract The extraction of flavonoids Platycladus orientalis by microwave was plimized. Taking the yield of flavonoids as index, the best extraction process was investigated by orthogonal experiment. The optimal condition is: ethanol concentration 60%(V), solidliquid mass ratio 1∶20, microwave time 4 min, microwave power 385 W.Certification experiment was done under these conditions, the extraction yield of flavonoids in Platycladus orientalis was 5905%.Compared with the direct heating extraction, microwave extraction can greatly shorten the extraction time, decrease the extraction dosage, and improve the yield of the extractants. Quality analysis was investigated for the extracted active ingredients and results showed that the extractants were determined to be from Platycladus orientalis.
