Tripterygium wilfordii Hook. f. induced-hepatotoxicity was the main limitation for its usage in clinic. Qingluo Tongbi formulation showed obvious attenuation for hepatotoxicity in clinic and fundamental research in vivo. To explore the potential mechanism of the attenuation, we conducted a study on the plasma metabolomic profiles of T. wilfordii and Qingluo Tongbi formulation in rats by a sensitive gas chromatography-mass spectrometry (GC-MS/MS) method. In plasma samples, a total of 72 compounds were analyzed by EI source MS, and were successfully identified by matching NIST database. The semi-quantification results were then calculated by OPLS-DA model with SIMCA-P 13.0 software. The three groups were clearly distinguished in OPLS-DA score plot. In addition, the observation values of Qingluo Tongbi formulation showed the obvious trend towards the control levels, suggesting the detoxicity effect of the formulation. Variation metabolites were further analyzed by VIP and One Way ANOVAs, and the results showed a significant increase in compounds of glycogenic amino acids, such as alanine, proline, serine and glutamine after the administration of T. wilfordii, indicated that the tissue proteins were decomposed and amino acids were leakage into blood. Qingluo Tongbi formulation could reverse the amino acids into normal level. On the contrary, the levels of glucose, lactic acid and hydroxy butyrate decrease, and the formulation can relieve the disorder in the levels of lactic acid, suggesting the regulation of the energy metabolism. Additionally, the level of branched chain amino acid was decreased, suggested the toxicity was induced, but the formulation cannot increase it into the normal levels. Nevertheless, all the above results suggested that the classical Qingluo Tongbi formulation displayed the liver protection effect by adjusting the amino acid levels and regulating the energy metabolism. Qingluo Tongbi formulation was developed based on traditional Chinese medicine theory "detoxicity compatibility", and contained Panax notoginseng (Burk.) F. H. Chen to nourish blood and absorb clots. Modern pharmacology suggested that its liver protection effect was correlated with the promotion of protein synthesis. Another important herb is Rehmannia glutinosa Libosch., which can regulate the energy metabolism. Both were consistent with the metabolomic results in this study, which explained the potential mechanism of "detoxicity compatibility" theory. Therefore, the currently developed metabolomic approach and the obtained results would be highly useful for the comprehensive toxicity studies for other herbal medicines and various complex deoxicity formulations.
