| Abstract: | Objective：To compare the effects of four kinds of processes on the extraction of total flavonoids from LianXing JiDou（Oxytropis falcata Bunge）. Methods：The contents of total flavonoids from LianXing JiDou were detected by NaNO2-Al（NO3） 3 chromatometry, the yield and the purity of total flavonoids were taken as the indexes, total flavonoids were extracted with the processes including water-extraction alcohol-precipitation and acid-hydroly-sis, water-extraction, alkaline-extraction and acid-precipitation, water-extraction and acid-hydrolysis. Results： The best extraction process for LianXing JiDou was water-extraction and acid-hydrolysis. The extraction percentage and the purity of total flavonoids were 1.6%and 11.26%respectively. Conclusion：The process could be used to extract total flavonoids from LianXing JiDou, which is reliable, simple and practicable. |
