Popis: Danggui Buxue Tang (DBT), a traditional Chinese medicine (TCM) formula for 'invigorating qi and enriching blood', has been reported to produce a good effect on chronic fatigue syndrome (CFS). However, the related mechanism remains largely undetermined. This study devised a metabolomics approach with GC-MS combined with pattern recognition to estimate the extent to which DBT alleviated CFS induced by food restriction and force swimming in rats. After 4 weeks of treatment, the endurance capability of rats was significantly better, and the motionless time was significantly shorter in the DBT group than in the CFS model group. Moreover, the activities of superoxide dismutase and glutathione peroxidase increased, whereas the levels of malondialdehyde, interleukin 6, and tumor necrosis factor alpha decreased in the DBT treatment group. Fifteen significantly changed metabolites were observed in the serum of rats with CFS, which was reversed markedly by DBT treatment. Metabolic pathway analysis showed that DBT could possibly alleviate CFS in rats by regulating the biosynthesis of phenylalanine, tyrosine, and tryptophan and the metabolism of glycine, serine, threonine, glycerolipid, glyoxylate, dicarboxylate, and tyrosine. It was observed that the metabolism of glycine, serine, and threonine was most closely related to the improvement in CFS by DBT treatment. This study showed that DBT could improve CFS effectively, and metabolomics was a powerful means to gain insights into the TCM formulas against CFS.
