[Progress of serum pharmacochemistry of traditional Chinese medicine and further development of its theory and method].

Serum pharmacochemistry of traditional Chinese medicine (TCM) is designed to screen the efficacy material base of TCMs from the constituents absorbed into the blood after oral administration. The theory and method is in accordance with the effect characteristics of TCMs, and reflects the interaction between the body and the drugs, has become an effective pathway for researching the efficacy material base of TCMs which has been recognized and used widely. In the paper, the previous research contents and methods of the serum pharmacochemistry of TCM were reviewed, and on the basis of the further validity of the special administration form of the TCM formula and the corresponding property to TCM syndrome, the new strategy of serum pharmacochemistry of TCM integrating the metabonomics technologies was put forward. According to the strategy, we take the biological characters of TCM syndrome as a research starting point, taking TCM formula as object, using the metabolic biomarkers of syndromes or disease to evaluate the therapeutic effect of formula and screen the compounds of TCMs in serum which are highly correlated with the metabolic biomarkers through the correlation analysis, and by further biological validation to finally confirm the efficacy material basis of TCMs. Integrating with the systems biology technologies, the theory and method of serum pharmacochemistry of TCM will further develop, and open a new chapter in the interpretation of the theory of TCM.
