AIM : To study the extraction kinetical deviation rules of muhicomponents in single and formula for the traditional Chinese materials medica. METHODS: By the established kinetics model of the components extracted form the Chinese medicine compound prescription(KMCECMCP) , the kinetical profile deviations of berberine alkaloids in Rhizoma Coptidis and Zuojin formulae were carried out, with analyses of berberine alkaloids,ρ2 and w0 by HPLC chromatographic fingerprint, with deterimation of V0, V1, V2 by water absorbing, with fited M,α,N,β,L...
