Objective: To optimize extraction technology of total flavonoid from Malus hupehensis by entropy-weighting method. Method: With yield of extract
the content of total flavonoid and phloridzin as comprehensive evaluation indexes
the concentration and dosage of solvent
extraction time were selected as factors
weight of which were determined by entropy-weighting method
extraction technology was optimized by orthogonal test which was realized by Matlab. Result: Optimum extraction technology was:reflux extracted 3 times with 10 folds the amount of 70% ethanol
1 h each time. Conclusion: Entropy-weighting method could be used in optimizing of extraction technology for traditional Chinese medicine
calculation amount of orthogonal test could be reduced by Matlab programming.
