Objective: To explore the effect on total flavonoids’content of compound Pyrola with different extraction process and optimize the best extraction process. Method: Flavonoid compounds were extracted from compound Pyrola with different solvent
water and alcohol respectively. Orthogonal test was used to determine the best extraction process of compound Pyrola flavonoids with the content of total flavones as the marker. Result: The more effective way to extract total flavones was extraction with 20 times amount of 60% alcohol under reflux for 1 hour. Conclusion: This method obtains more effective components. It is stable and reliable.
