The urine and bile samples were collected with 24 h after oral administration of GGFTT. A total of 34 compounds, including 11 parent compounds and 23 metabolites were unambiguously or tentatively identified. Our results indicated that glucuronidation, oxidation and methylation were the major metabolic pathways of the constituents in GGFTT. In addition, the results of this work also demonstrated the feasibility of HPLC-ESI-Q-TOF/MS for reliable characterization of the in vivo metabolites from herbal preparations.展开更多

However, appropriate strategies and supportive evidences are still lacking to uncover the synergistic or additive combinations. The present investigation aimed at seeking a screening strategy to identify the targeted combinations in GuG e FengT ong Tablet(GGFTT), an herbal formula. Two compounds, belonging to different chemical classes, were combined with different concentration ratios and their anti-inflammation effects were investigated. The most significant anti-inflammatory combinations were evaluated by combination index(CI) method(additive effect, CI = 1; synergism, CI < 1; antagonism, CI > 1). The modulating effects of candidate combinations on pro-inflammatory cytokines and MAPKs signaling pathway were also detected. Two combinations, "biochanin A + 6-gingerol"(Bio-6 G) and "genistein + 6-gingerol"(Gen-6 G), showed synergistic effects(CI < 1), and Bio-6 G was selected for further study. Compared with single compound, Bio-6 G could synergistically inhibit the production of pro-inflammatory cytokines(TNF-α, IL-1β, and IL-6) and the activation of MAPKs signaling pathway in LPS-stimulated RAW264.7 cells. The combined results showed that Bio-6 G was a synergistic anti-inflammatory combination in GGFTT. Our results could provide a useful strategy to screen the synergistic combinations in herbal formulae.展开更多
