[Nuclear magnetic resonance-based metabonomics for sedative and hypnotic effect of Banxia Houpo decoction].

Insomnia was a common disease, which might be correlated with γ-aminobutyric acid A (GABAA) receptor mechanism, cytokine regulatory mechanism, excitatory amino acid mechanism and hydroxytryptamine (5-HT) receptor mechanism, but the correlations between these independent mechanisms and pathological characterization were still unclear. To further explore the effect of Banxia Houpo decoction on known or unknown biological pathways during treatment of insomnia, the metabonomics method based on ¹H-NMR was developed for detecting the significant changes in metabolomics after the administration with Banxia Houpo decoction in pentobarbital sodium-induced rat sleeping experiment. Serum and urine samples were analyzed by ¹H-NMR.
