Pharmacokinetics, distribution and excretion of inulin-type fructan CPA after oral or intravenous administration to mice

The aim of this work has been to establish and validate a simple and efficient method to detect the concentration of inulin-type fructan CPA from the roots of Codonopsis pilosula (Franch.) Nannf. in biosamples, and then apply it to evaluate the pharmacokinetics behavior, distribution character in tissue and excretion in mice. In this work, fluorescein isothiocyanate (FITC) was used to label CPA. Then FCPA was intravenously and orally administered to mice at different doses. In both i.v and p.o administration, FCPA concentration slowly declined in the circulatory system with a much longer
