塞内西奥丑闻布奇。-火腿.,一种临床上常用的中药,表现出各种药理特性,包括消炎药,抗肿瘤,抗病毒,和抗菌活性。然而,它的水提取物的化学成分和代谢物没有被充分理解,限制了进一步的研究。在这项研究中,千里光的化学成分和代谢过程,在体内(血浆,粪便,尿液,和胆汁)和体外(肠道菌群和肝微粒体),基于超高效液相色谱与混合四极杆-轨道阱高分辨率质谱联用技术进行了表征。此外,在粪便样本和培养的肠道微生物群中可检测但在肝微粒体中不存在的代谢物被鉴定为肠道微生物群的特征性代谢物.收集肠道菌群特征代谢产物的靶标,然后通过KEGG富集分析探索潜在的途径。因此,总共初步鉴定了133种化学成分,包括35种有机酸,21种生物碱,19类黄酮及其糖苷,17种苯丙素类化合物,10种蓝花兰达酮,和其他31种化合物。值得注意的是,其中12个是潜在的新化合物。此外,对大鼠中的39种原型成分和109种代谢物进行了鉴定和表征,包括体内102种代谢产物和体外52种代谢产物(大鼠肠道菌群51种,大鼠肝微粒体24种)。主要的代谢途径包括氧化,reduction,水解,甲基化,葡糖醛酸化,磺化,和乙酰化反应。此外,KEGG富集分析显示,肠道菌群的特征性代谢产物可能与ErbB,福克斯,mTOR,和MAPK信号通路,表现出抗炎和抗肿瘤作用。总之,用快速、准确的方法对千里光的化学成分和代谢产物进行了全面鉴定,为深入研究千里光的物质基础及其临床应用提供科学依据。
Senecio scandens Buch.-Ham., a traditional Chinese medicine commonly used clinically, exhibits various pharmacological properties, including anti-inflammatory, anti-tumor, antiviral, and antibacterial activities. However, its water extracts\' chemical components and metabolites are inadequately understood, limiting further research. In this study, the chemical components and metabolism processes of
Senecio scandens, both in vivo (plasma, feces, urine, and bile) and in vitro (gut microbiota and liver microsomes), were characterized based on ultra-high performance liquid chromatography coupled with hybrid quadrupole-orbitrap high-resolution mass spectrometry. Additionally, metabolites detectable in fecal samples and intestinal microbiota incubated but absent in liver microsomes were identified as characteristic metabolites of intestinal microbiota. The targets of the characteristic metabolites of intestinal microbiota were collected, followed by exploration of potential pathways through KEGG enrichment analysis. As a result, a total of 133 chemical components were preliminarily identified, including 35 organic acids, 21 alkaloids, 19 flavonoids and their glycosides, 17 phenylpropanoids, 10 jacaranda ketones, and 31 other compounds. Notably, 12 of these were potentially novel compounds. In addition, 39 prototype components in rats and 109 metabolites were identified and characterized, including 102 in vivo and 52 metabolites in vitro (51 in rat gut microbiota and 24 in rat liver microsomes). The main metabolic pathways include oxidation, reduction, hydrolysis, methylation, glucuronidation, sulfonation, and acetylation reactions. Furthermore, KEGG enrichment analysis revealed that the characteristic metabolites of intestinal microbiota may be related to the ErbB, FoxO, mTOR, and MAPK signaling pathways, exhibiting anti-inflammatory and anti-tumor effects. In summary, the chemical components and metabolites of
Senecio scandens were comprehensively identified using a rapid and accurate method, providing a scientific basis for the in-depth study of the material basis and its clinical application of
Senecio scandens.
