The extraction method of effective components of
traditional Chinese medicine composition for treating knee
osteoarthritis based on
entropy weight method and response surface method belongs to the technical field of
traditional Chinese medicine extraction, establishes the
content determination method of index components in the composition, i.e.,
sinomenine,
magnoflorine,
paeonol glycoside,
paeoniflorin and dioscin, and carries out methodology investigation; the comprehensive
score of index component content is calculated by the
entropy weight method as an evaluation index, the influence factors are
ethanol concentration,
solid-
liquid ratio and soaking time, the experiment is designed by applying the response surface method, the index weight is determined by the comprehensive weighting theory of evaluation index, the comprehensive
score is calculated, the multiple quadratic regression model of comprehensive
score and investigation factors is established, the variance analysis is carried out, the optimal process is predicted and verified, and the optimized extraction process parameters of Jiantongkang are determined. The extraction condition optimization research of index components of the composition based on the
entropy weight method and the response surface method is strong in pertinence, simple in operation, high in accuracy, scientific and reasonable in process, and is suitable for the
content determination of medicinal material effective components.
