ABSTRACT

Objective:

To construct the targeting evaluation method of traditional Chinese medicine (TCM) preparations based on supramolecular Qi chromatography theory, and to study the liver targeting effect of Bupleuri Radix on Pien Tze Huang.

Method:

The molecular connectivity index (MCI) was used to analyze the characteristics of imprinted template and liver targeting tendency of TCM mainly attributed to liver meridian and components of Pien Tze Huang, and combined with target dynamics and total statistical moment principle, aimed at the independent action characteristics of multi-component imprinted template of TCM, a method for evaluating the targeting of TCM preparations was established. Hepatoma rats in Pien Tze Huang group, Bupleuri Radix<italic> </italic>group, Pien Tze Huang+Bupleuri Radix group and blank group were tested and verified.

Result:

After the average value of MCI of TCM mainly attributed to liver meridian was deducted, the MCI similarity between Pien Tze Huang group and Bupleuri Radix group was 0.376 8, Pien Tze Huang+Bupleuri Radix group and Bupleuri Radix group was 0.988 2, so it was predicted that Bupleuri Radix could enhance the liver targeting of Pien Tze Huang. A system for evaluating the targeting of TCM compounds was established, including relative total uptake efficiencyRUE<sub>T</sub>), relative total concentration (RC<sub>T</sub>), relative imprinted tendency (RIT<sub>T</sub>) and relative imprinted variance (RIV<sub>T</sub>). The RUE<sub>T</sub> and RC<sub>T</sub> of liver were the highest in all tissuesRUE<sub>T</sub>=1.88>1,RC<sub>T</sub><italic>=</italic>2.30>1), and the corresponding values of other tissues were all <1, indicating that Pien Tze Huang combined with Bupleuri Radix could increase its distribution in liver and enhance liver targeting. Except for plasma, the RIT<sub>T</sub> and RIV<sub>T</sub> of other tissues fluctuated around 1.0, indicating that targeted modification did not change imprinted tendency of Pien Tze Huang and had no significant effect on the types of components.

Conclusion:

Under the guidance of supramolecular Qi chromatography theory, a targeting evaluation parameter system can be established to characterize the multi-component imprinted effect of TCM preparations by MCI and total statistical moment parameters, so as to realize the evaluation of targeting of TCM preparations. The addition of Bupleuri Radix can increase the liver targeting of Pien Tze Huang.
