[¹H-NMR-based metabonomics on chemical component groups with toxicity alleviation effect to Realgar in Niuhuang Jiedu tablet].

To study the chemical component groups with toxicity alleviation effect to Realgar in Niuhuang Jiedu tablet based on ¹H-NMR metabonomics. Twenty-four male Wistar rats were divided into four groups： control group, R group (treated with Realgar), RRSPG group (treated with Realgar, the root and rhizoma of Rheum palmatum, the root of Scutellaria baicalensis, the root of Platycodon grandiflorum and the root and rhizoma of Glycyrrhiza uralensis) and RC group (treated with total anthraquinones from the root and rhizoma of R. palmatum, total flavonoids from the root of S. baicalensis, total saponins from the root of P. grandiflorum, total flavonoids and saponins from the root and rhizoma of G. uralensis). Based on ¹H-NMR spectra of urine and serum from rats, PLS-DA was performed to identify different metabolic profiles.The metabolic profiles of R group were different from that of control group, while the metabolic profiles of RC group were almost similar to control group.Total anthraquinones from the root and rhizoma of R. palmatum, total flavonoids from the root of S. baicalensis, total saponins from the root of P. grandiflorum, total flavonoids and saponins from the root and rhizoma of G. uralensis regulated energy, choline and amino acid metabolism and gut flora disorder affected by realgar's toxicity.
