Abstract
Artemisia species have been regarded as an important source of ethnic medicinal plants, such as A. annua and A. capillaris, both of which are widely used in clinical treatment. The clinical efficacy of A. japonica is similar to that of A. capillaris, but fewer pharmaceutical studies have been reported. Given that the extracts of A. japonica were observed to reduce the rectal temperature of febrile rats induced by LPS, this study was designed to demonstrate this regulatory effect of the extracts, with a particular focus on the lipidomic profiling of the febrile rat hypothalamus. A total of 72 differential metabolites were filtered out and the association between lipid profiling and potential mechanism was explored. Sphingolipid, glycerophospholipid, arachidonic acid and ether lipid metabolism pathways were significantly enriched. TNF-α, IL-6 and PGE2 cytokines in the hypothalamus were significantly downregulated by the intervention of the extracts of A. japonica. Enzymatic reaction enrichment analysis suggested that PEMT and COX-2 might be potential targets of the efficacy, and which were testified to be downregulated by the ELISA assay under the extracts intervention.
期刊介绍：
This journal is an international medium directed towards the needs of academic, clinical, government and industrial analysis by publishing original research reports and critical reviews on pharmaceutical and biomedical analysis. It covers the interdisciplinary aspects of analysis in the pharmaceutical, biomedical and clinical sciences, including developments in analytical methodology, instrumentation, computation and interpretation. Submissions on novel applications focusing on drug purity and stability studies, pharmacokinetics, therapeutic monitoring, metabolic profiling; drug-related aspects of analytical biochemistry and forensic toxicology; quality assurance in the pharmaceutical industry are also welcome.
Studies from areas of well established and poorly selective methods, such as UV-VIS spectrophotometry (including derivative and multi-wavelength measurements), basic electroanalytical (potentiometric, polarographic and voltammetric) methods, fluorimetry, flow-injection analysis, etc. are accepted for publication in exceptional cases only, if a unique and substantial advantage over presently known systems is demonstrated. The same applies to the assay of simple drug formulations by any kind of methods and the determination of drugs in biological samples based merely on spiked samples. Drug purity/stability studies should contain information on the structure elucidation of the impurities/degradants.
