Abstract

Objective Bile-processed Coptidis Rhizoma (CR) exhibits stronger cold properties and central effect. However, the commonly used bile includes pig/cattle/sheep bile. It is currently unclear which kind of bile performs the best synergistic effect, and the enhanced efficacy is mainly contributed by what components. In this work, a comparative study on pig/cattle/sheep bile processed CR (pCR/cCR/sCR) was carried out. Materials and Methods Firstly, the anxiety model of sthenic heat type was established. Then, pharmacological research involving general state observation, biochemical examination (succinate dehydrogenase, glucokinase, corticosterone, adrenocor ticotropic hormore), pathological evaluation (liver and hippocampus tissue), and behavioral tests (elevated plus maze, open field test) was implemented. Finally, chemical assessment involving high-performance liquid chromatography (HPLC) fingerprints of pCR/cCR/sCR extracts and mass spectrograms of pig/cattle/sheep bile were performed in combination. Results cCR performed the most prominent enhancement in improving hyperactive energy metabolism in liver and abnormal hyperactivity of hypothalamic–pituitary–adrenal axis axis. As for chemical assessment, HPLC fingerprints of pCR/cCR/sCR extracts indicated that alkaloid components detected in cCR extracts were relatively low, mass spectrograms of pig/cattle/sheep bile suggested that bile acids in cattle bile were relatively abundant, and the contents of taurocholic acid, glycocholic acid, and glycodeoxycholic acid were particularly high. Conclusion Cattle bile could be specified as the processing excipient for bile-processed CR, and the high levels of taurocholic acid, glycocholic acid, and glycodeoxycholic acid mainly contributed to the enhanced efficacy of cCR.
