[Objective] To study extraction technology of flavonoids from Aloe arborescens Mill.by microwave method.[Method] Taking extraction rate of flavonoids as index,singer-factor experiments and orthogonal test were applied to optimize the extraction technology of flavonoids from Aloe arborescens Mill.by microwave method.[Results] The optimum extraction technology of flavonoids was as follows:solid-liquid ratio of 1:50,ethanol concentration of 80%,microwave power of 560 W and microwave treatment time of 40 s.Under this condition,the extraction rate of flavonoids was 5.604%.[Conclusion] Compared with ethanol extraction method,microwave method was characteristic of shorter extraction time,less ethanol volume and higher extraction rate,which was an ideal method to extract flavonoids from Aloe arborescens Mill..
