Title: Study on extraction process of Scutellaria barbata
Abstract: Objective:To study the optimum ethanol extraction process. Methods: The extraction rate of extractum and total flavonoids as well scutellarin was choosen as the assessment index. The optimum ethanol extraction process was selected with the orthogonal design. Results: The optimum ethanol extraction process conditions follow as: adding 10 fold of 75% ethanol, extracting for 2.0h and twice in all. Conclusion: The average extraction rate of extractum and total flavonoids as well scutellarin was 13.6%, 91.7%, 78.4%(n=3), respectively.
