RESULT: The K or K of laetrile, paeoniflorin and paeonol had no significant difference at concentration of 19.2~304.8, 18.4~329.5 and 7.8~125 μg/mL respectively or in four different regions of rat intestinal tract, the absorption quantity of laetrile, paeoniflorin and paeonol was proportional to its concentration respectively and the phenomena were not observed saturable. Except for Paeonol, the K and K of laetrile and paeoniflorin had no significant difference at pH value 5.0~7.4. The K or K of laetrile and paeoniflorin from the extration which contains one kind of active components was significantly less than that of same components from GuizhiFuling Capsule content.
