摘要(Abstract)：
蝉棒束孢(蝉花)Isariacicadae是药食两用真菌,具有多种生理活性,但其物质基础依然不明确。据此,本实验采用长期高脂高胆固醇饮食制备肥胖小鼠模型,灌胃给予蝉棒束孢乙醇提取物、水提取物和氢氧化钠碱水提取物等不同提取物,测定其血清中总胆固醇(T-CHO)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)和高密度脂蛋白胆固醇(HDL-C)等脂质代谢指标;观察其肝、肠组织的病理变化情况,以及肠道内容物中的菌群结构等,综合分析并筛选出蝉棒束孢改善肥胖的有效提取物或成分,为其进一步的深加工提供基础。结果表明,蝉棒束孢的不同溶剂提取物均可不同程度减缓高脂高胆固醇饮食诱导小鼠肥胖,同时改善其脂质代谢情况,减轻脂肪在肝脏中的堆积,减缓肠组织损伤,并调整肠道菌群结构,蝉棒束孢醇提取物效果较优,但其具体作用机制还有待进一步的研究揭示。
