Impacts of multicomponent environment on intrinsic dissolution rate of berberine in biopharmaceutics classification system of Chinese materia medica / 中国中药杂志

ABSTRACT

To illustrate the intrinsic dissolution rate(IDR) involved in biopharmaceutics classification system of Chinese materia medica(CMMBCS), investigate the effect of artificial multicomponent environment on IDR of berberine, by using a non-disintegrating disk, and summarize related rules by using the obtained data. Progressive levels design was used to investigate the effects of single component environment (puerarin, baicalin, and glycyrrhizic acid); double-component environment(puerarin+baicalin, puerarin+ glycyrrhizic acid, baicalin+glycyrrhizic acid); and triple-component environment(puerarin+baicalin+glycyrrhizic acid) on IDR of berberine, laying a foundation for further researches on the absorption mechanism of multiple components.
