Objective: To optimize extraction process of total flavonoids from poplar buds. Method: With the content of total flavonoids from poplar buds as index
based on single factor tests
orthogonal test was adopted to optimize extraction technology by taking ethanol concentration
extraction time and solid-liquid ratio as factors. Result: Optimum process determined by orthogonal test was as following:extracted tiwce with 13 times the amount of 90% ethanol for 30 min per time;The content of total flavonoids was 28.82%.The best process optimized by central composite design-response surface methodology was as following:extracted twice with 14 times the amount of 80% ethanol for 24 min per time;The content of total flavonoids was 31.14%. Conclusion: Central composite design-response surface methodology was better than orthogonal method in accuracy
combined two methods for optimizing application of extraction process for traditional Chinese medicine had good predictability.
