Objective To optimize the diphasic dynamic extraction technology of anthraquinone aglycone from Rheum palmatum L. Methods With the content of anthraquinone aglycone as an index ,multiple of extraction solvent ,extraction temperature ,extraction time and extraction times taken as investigation factors ,extraction technology of anthraquinone aglycone from Rheum palmatum L was opti-mized by L9 (34 ) orthogonal test .Results Optimal extraction technology was as follows:10 times amount of solvent was added ,extrac-tion temperature was 80℃ and extraction was conducted three times ,1.5 hours each time.Conclusions This optimized extraction technology is feasible ,stable and reasonable with high yield of anthraquinone aglycone .
