Title: Optimization of the extraction technology of flavonoids from HERBA TARAXACI.
Abstract: [Objective] To optimize the extraction technology of flavonoids from HERBA TARAXACI.[Method] By adopting orthogonal experiment and artificial neutral network,the content of total flavonoids was determined,the effects of extracting time,extracting temperature,solid-liquid ratio and ethanol concentration on the extraction process were studied,based on which the extraction technology was optimized.[Result] The effects of factors on the extraction decreased as solid-liquid ratioethanol concentrationextracting timeextracting temperature,and the optimum conditions simulated by artificial neural network were extracting temperature 75 ℃,ethanol concentration 65%,solid-liquid ratio 1∶30 g/ml and extracting time 3 h.[Conclusion] The artificial neural network based on orthogonal test could be used in optimizing the extracting technology of flavonoids from HERBA TARAXACI.
