Title: Study on the Semi-bionic Extraction Technology of Total Flavonoids from RADIX WIKSTROEMAE
Abstract: [Objective] To study the opyimum semi-bionic extraction technology of total flavonoids from RADIX WIKSTROEMAE. [Method] Orthogonal test 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] When RADIX WIKSTROEMAE sample power was refluxed at 80 ℃ for 70∶ 35∶ 35 min for three times with 14 volumes of 70% ethanol, the yield of total flavonoids was the highest at 4.73%. [Conclusion] Semi-bionic extraction was applicable to extract total flavonoids from RADIX WIKSTROEMAE.
