Objective: To study the separation and purification of total flavonoids determined experimental conditions of Chinese medicine dandelion flowers. Methods: the total flavonoids by macroporous resin D-101 to dandelion flowers was purified, determine the best purification the purification condition. Results: the optimum purification conditions of pH3.0, 2BV, sample volume, flow rate of 2BV/h. Conclusion: under the optimal conditions, total flavone from dandelion flowers best purification purification effect, provide better scientific basis for total flavonoids from dandelion flowers.
