Abstract:
Araloside A is one of the main active ingredients of Aralia taibaiensis. In this study, HPLC-MS/MS analysis method of araloside A in the main organs of SD rats was established. At the same time, the content of araloside A in the main organs (heart, liver, spleen, lung, kidney, brain) after oral administration with araloside A (50 mg•kg⁻¹) were determined to explore the tissue distribution characteristics of araloside A in vivo. The results showed that the methodological study of araloside A in the main organs of SD rats met the requirements, araloside A distributed in heart, liver, spleen, lung, kidney and brain tissues reached peak at 1 h or 2 h after oral administration with 50 mg•kg-1.The distributions of araloside A at different time points after administration were distinct as follows： the content of araloside A at 20 min：liver>heart>spleen>lung>kidney>brain; the content of araloside A at 1 h： liver>spleen>kidney>lung>heart>brain; the content of araloside A at 2 h： liver>kidney>heart>spleen>lung>brain; the content of araloside A at 4 h： kidney>liver>spleen>heart>lung>brain; the content of araloside A at 8 h： spleen>heart>liver>kidney>lung>brain. Therefore, araloside A was mainly distributed in liver tissue, which had a certain correlation with the common use of Aralia taibaiensis in the treatment of hepatic disease. In addition, araloside A shows a low content but an obvious distribution in brain tissues, which indicates that the drug can pass through blood-brain barrier, and provides the basis for the study of araloside A in brain tissue.
