TITLE: Full spectrum analysis of chemical constituents of Sargassum fusiforme and its in vitro anti-neuroinflammatory activity
摘要: 目的 研究羊栖菜的化学成分组成及体外抗神经炎症活性,为其开发利用以及药效物质研究提供参考。方法基于超高效液相飞行时间质谱联用技术(UHPLC-QTOF-MS/MS)和气相色谱-质谱联用技术(GC-MS/MS)对羊栖菜中化学成分进行全谱分析。利用脂多糖(1μg/mL)建立小鼠小胶质细胞BV2的炎症模型,以帕罗西汀(5μg/mL)为阳性对照药物,通过CCK-8法检测20、40、60、80、100μg/mL羊栖菜提取物作用24h后对细胞活性及形态的影响,通过酶联免疫吸附法检测40、60、80μg/mL羊栖菜提取物作用24h后对细胞上清液中肿瘤坏死因子α(TNF-α)、白细胞介素6(IL-6)含量的影响。结果经UHPLC-QTOF-MS/MS分析共鉴定出103种非挥发性成分,经GC-MS/MS分析共鉴定出60种挥发性成分。40、60、80μg/mL羊栖菜提取物可显著降低因脂多糖诱导而异常升高的BV2细胞活化程度和细胞上清液中TNF-α、IL-6的含量(P<0.05或P<0.01)。结论本研究建立了海藻羊栖菜的化学成分全谱,并证实了羊栖菜具有一定的体外抗神经炎症活性。
ABSTRACT: OBJECTIVE To study the composition of chemical constituents of Sargassum fusiforme and its in vitro anti- neuroinflammatory activity ,and to provide reference for its development and utilization and the study of pharmacodynamic substances. METHODS UHPLC-QTOF-MS/MS analysis method and GC-MS/MS method were used to analyze the chemical constituents of S. fusiforme . The lipopolysaccharide (1 μg/mL)was adopted to establish the inflammatory model of neuromicroglia BV2. Using paroxetine (5 μg/mL)as positive control ,CCK-8 assay was used to detect the effects of the extracts of S. fusiforme (20,40,60,80,100 μg/mL)on the activity and morphology of neuromicroglia BV 2. The effects of the extracts of S. fusiforme (40,60,80 μg/mL)on the contents of tumor necrosis factor α(TNF-α)and interleukin- 6(IL-6)in cell supernatant were detected by ELISA. RESULTS A total of 103 non-volatile constituents were identified by UHPLC-QTOF-MS/MS ,and 60 volatile constituents were obtained by GC-MS/MS. The extracts of S. fusiforme (40,60,80 μ g/mL) could significantly reduce the abnormally increased activation of neuromicroglia BV 2 and the contents of TNF-α and IL-6 due to lipopolysaccharide (P<0.05 or P<0.01). CONCLUSIONS The study establish the full spectrum of chemical constituents of S. fusiforme ,and it is confirmed that fusiforme has certain in vitro anti-neuroinflammatory activity.
