Abstract:
AIM: To determine the suitable condition and the optimal parameters for the extraction and purifiction process of total flavonoid compounds in Scutellaria baicalensis. METHODS: It was investigated by orthogonal experiment design of form L_9(3~4) with the extraction percentage of the total flavonoid compounds and baicalin from Scutellaria baicalensis as the standard. RESULTS: The optimal condition of extraction was with water as much as ten times of the medicine amount and was boiled for 2 h and three times,and the optimal condition of purifiction was as follows: solution concentration 0.25 g(crude medicinal materials) /mL,adjusting pH to 2,80 ℃ heat preservation up to 60 min, 50% alcohol as precipitant and the precipitated adjusted pH to 4.0. CONCLUSIONS: The optimal process is rational,practical and adapted to industry production.
