| Abstract: | Objective：The microwave-assisted extraction （MAE） technique was used to extract flavonoids from Scutellaria baicalensis Georgi.Methods：The effects of solvots,liquor-solid ratio,extraction temerature,particle size,microwave power and extraction time on the extracting rates of flavonoids were determined by single factor test.Results ：When 50% ethanol as solvents,liquor-solid ratio was 20mL/g and microwave power was 800W,40 mush of particles sample was treated at 90℃ for 8 min,the highest extraction rate of flavonoids was 99.42% which was bigher than reflue extraction method for 4h.Conclusion：MAE has characteristics of high officiency and selectivity,saving time and energy for extracting flavonoids from Scutellaria baicalenssi Georgi. |
