Abstract:
For the effects of multi-component environment on the solubility and permeability of single components,and the problems of biopharmaceutical attribute classification of single components in the compound prescriptions environment,baicalein was used as the research object in this study to investigate the biopharmaceutic attributes of single-component and their traditional Chinese medicine( TCM) biopharmaceutic attributes in the multi-component environment of Gegen Qilian Decoction. Shaking flask method,intrinsic dissolution rate test and HPLC were used to determine solubility of baicalein. Markers specified by FDA were utilized as permeable boundary reference materials to verify the applicability of the single-pass intestinal perfusion method( SPIP),and the quantitative research on the permeability of baicalein was also conducted. It is concluded that baicalein could be categorized as BCS-Ⅱ drug based on its low solubility and high intestinal permeability values,and it may be categorized into CMMBCS-I in the multi-component environment of Gegen Qilian Decoction due to its poor solubility but enhanced solubility and permeability in compound environment. This study could provide verification ideas for clinical determination of the best human oral dose of baicalein,and provide the data basis for the study of biopharmaceutics classification system of Chinese materia medica( CMMBCS).
