Abstract:
ObjectiveTo explore the regulatory effect of polysaccharides and n-butanol fractions of Atractylodis Rhizoma stir-fried with bran on the plasma metabolites of spleen-deficient rats， and then to elucidate their mechanisms of spleen-enhancing effects. MethodForty male SD rats were randomly divided into the blank group， model group， polysaccharide group （FD group， 0.075 6 g·mL-1·d-1）， n-butanol fractions group （FZ group， 0.012 1 g·mL-1·d-1）， with 10 rats in each group. Except the blank group， the other three groups used the compound factors of overwork， dietary disorders and intragastric administration of Sennae Folium decoction to replicate the rat model of spleen deficiency. After the end of modeling， the FD group and FZ group were given the corresponding medicinal solution by gavage for 7 d， meanwhile， the blank group and model group were given an equal volume of saline. The plasma samples from rats in the blank， model， FZ and FD groups were analyzed by ultra-high performance liquid chromatography-quadrupole/electrostatic field orbitrap high-resolution mass spectrometry （UHPLC-Q-Orbitrap-MS）， multivariate statistical methods were used to process the data and screen differential metabolites， and metabolic pathway enrichment analysis of the screened differential metabolites was performed using the Kyoto Encyclopedia of Genes and Genomes （KEGG)）database and MetaboAnalyst 5.0. ResultThe results of multivariate statistical analysis showed that there were significant differences in plasma metabolites between the model group and blank group， FZ group and model group， FD group and model group. There were 380 differential metabolites between the blank group and the model group， of which 78 and 57 were called back by polysaccharides and n-butanol fractions of Atractylodis Rhizoma stir-fried with bran， respectively. Metabolic pathway enrichment results showed that the n-butanol fractions mainly affected glycine， serine and threonine metabolism， alanine， aspartate and glutamate metabolism， D-arginine and D-ornithine metabolism， which were summarized as amino acid metabolism， while the polysaccharides mainly affected glycine， serine and threonine metabolism， alanine， aspartate and glutamate metabolism， tricarboxylic acid cycle， biotin metabolism and thiamine metabolism. ConclusionBoth of polysaccharides and n-butanol fractions of Atractylodis Rhizoma stir-fried with bran have significant regulating effects on the metabolic abnormalities in spleen-deficient rats， in which the n-butanol fractions is mainly involved in amino acid metabolism， and the polysaccharides are involved in energy metabolism and cofactor and vitamin metabolism in addition to regulating amino acid metabolism.
