| Abstract: | Objective: To optimize extraction process of Matteuccia struthiopteris. Method: Orthogonal test was carried out to investigate influences of the concentration of ethanol,material-liquid ratio,extraction time and extraction times on extraction with yield of total flavonoids as index. Result: Optimum extraction technology was as follows: the concentration of ethanol was 70%, ratio of material-solvent was 1 : 12(g·mL-1),extracted 2 times with 1 h per time. Conclusion: Optimized extraction process was stable and reasonable. |
