Characterization of effective constituents in Acanthopanax senticosus fruit for blood deficiency syndrome based on the chinmedomics strategy

The fruit of (Rupr. and Maxim.) has been newly developed for the treatment of blood deficiency syndrome clinically, but the effective constituents are still unclear, restricting its quality control and the new medicinal development based on it. This study elucidated the efficacy of fruit (ASF) for treating blood deficiency syndrome and accurately characterize the constituents. Chinmedomics strategy was used to identify the metabolic biomarkers of the model and the overall effect of ASF was evaluated based on the biomarker when it showed intervention effects for blood deficiency syndrome. ultrahigh performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was used to analyze the components in the blood absorbed from fruit, and the components highly relevant to the biomarker are regarded as potential effective constituents for blood deficiency syndrome. Twenty-two of the 28 urine metabolites of blood deficiency syndrome were significantly regulated by fruit, 97 compounds included 20 prototype components, and 77 metabolites were found under the acting condition. The highly relevant constituents were isofraxidin, eleutheroside B, eleutheroside B1, eleutheroside E, and caffeic acid, which might be the effective constituents of fruit. It is a promising new medicinal resource that can be used for treating blood deficiency syndrome.
