    Abstract: The decoction of Alisma orientale is used as a traditional medicine for the treatment of hyperlipidemia in China with a long clinical history. The present study undertook a detailed investigation to compare the hypolipidemic effect and chemical composition of two extracts of Alisma orientale prepared by boiling water and organic reagent, respectively. Methods: The hyperlipidemic mice were induced by administration of a High-Fat Diet (HFD) for one month. The body weight of mice and the serum Cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), Superoxide Dismutase (SOD), malondialdehyde (MDA), aspartate Aminotransferase (AST) and alanine aminotransferase (ALT) levels were determined. Meanwhile, the chemical constituents of the extracts were characterized using liquid chromatography-quadrupole time of flight mass spectrometry (LC-QTOF-MS/MS). Results: The better hypolipidemic effect was observed in mice administered with the decoction compared to that of methanol extract. In addition, the liver protective effects were confirmed by the photographs stained with oil red lipid stain. As for the chemical constituents in the extracts, twenty major components were identified or characterized using LC-QTOF-MS/MS. Among them, eight oligopeptides were characterized for the first time and proved to only exist in the decoction of Alisma orientale. Conclusion: It is reasonable to assume that the oligopeptides may partially contribute to the hypolipidemic effect of Alisma orientale. The structural characterization procedures also provide a suitable method to analyze oligopeptide analogues in plant samples.

    Abstract: Objective: Acute liver injury (ALI) has become a major reason for emergency liver transplantation mortality worldwide. Diwuyanggan (DWYG), a hospital preparation of traditional chinese medicine, does a satisfactory job of treating liver disease, but its pharmacological mechanisms should be further investigated. Thus, we aimed to unravel the mechanisms of DWYG against ALI through a comprehensive approach integrating metabolomics and network pharmacology analysis in this study. Methods: An untargeted metabolomics based on ultra-high pressure liquid chromatography together with quadrupole time of flight mass spectrometry was applied to identify differential metabolites between normal mice and thioacetamide (TAA)-induced ALI mice. By utilizing network pharmacology, potential targets against ALI caused by TAA were excavated. Subsequently, the key targets were validated by real-time polymerase chain reaction assays. Results: DWYG alleviated TAA-induced ALI. Furthermore, 28 differential metabolites were identified with an association between ALI pathological processes and DWYG effects. The pathways involved in bile acid, glycerophospholipid, fatty acid, sphingolipid, tryptophan, and tyrosine metabolism. Then, we found 127 active compounds in DWYG and 26 hub genes associated with the treatment of ALI according to network pharmacology. Besides, according to Kyoto Encyclopedia of Genes and Genome analysis, sphingolipid signaling pathway was deemed as one of the main signaling pathways involved in DWYG anti-ALI, which was in agreement with the metabolomics findings. Further, a combined analysis was performed focusing on 7 key targets, including mitogen-activated protein kinase 1, mitogen-activated protein kinase 8, caspase 3, peroxisome proliferator-activated receptor gamma, albumin, carboxylesterase 1 and glucocerebrosidase, along with their related core metabolites and pathways. Confirmatory experiment further showed that DWYG could reverse the abnormal mRNA expression of these targets in TAA mice. Conclusion: This study revealed direct evidence for the preventive effect of DWYG against ALI and the related pharmacological mechanisms.
