| Abstract: | Objective To optimize the extraction procedure of flavonoids from Bauhinia championii Benth.Methods An orthogonal test was used to test the factors of extraction times,extraction times,alcohol concentration and solvent amount.The content of flavonoids was determined by spectrophotometry.Results The optimum extraction process was as follows:10 times the amount of 60% ethanol,3 times of extraction and 3 h each.The yield of extracted flavonoids reached 7.426%.Conclusion The method is simple and convenient, which can be used to extract flavonoids from Bauhinia championii Benth in large scale. |
