| Abstract: | Objective] To study the best semi-bionic extraction technology of total flavonoids from RADIX WIKSTROEMAE.Method] Orthogonal experiment was carried out to investigate the effects of extraction temperature(A),extraction time(B),solid-liquid ratio(C),and ethanol concentration(D) on the extracting yield of total flavonoids.Result] The optimal conditions for semi-bionic extraction were: 70% alcohol,1∶14(g ∶ml) of solid-liquid ratio,and extracting at 80 ℃ for 70∶35∶35 min for three times,the extracting yield of flavonoids under these conditions was 4.73%.Conclusion] Semi-bionic extraction was applicable to extracting total flavonoids from RADIX WIKSTROEMAE. |
