| Abstract: | Objective:To establish the optimum preparation procedure of flavonoids from Symphytum Officinal Linn by orthogonal design.Method:Using water as extracting liquid,the effect factors of temperature,time of extraction and ratio of material to solvent on the flavonids extracted from Symphytum Officinal Linn were studied through orthogonal design.Results:The optimum extraction conditions of flavonoids from Symphytum Officinal Linn were as follows:water as extraction solvent at 90 ℃ for 2.5 h,the ratio of material to solvent was 1∶40.Under the above conditions,percent content of flavonoids in Symphytum Officinal Linn extraction was 3.01%.Conclusion:This technological process is feasible and can be used for extracting flavonoids from Symphytum officinal Linn. |
