摘要
通过"代谢产物-效应检识"模式进行相关性分析,初步明确菟丝子在体内发挥拟雌激素作用的直接作用物质。以去势(卵巢摘除)雌性大鼠为研究对象,灌胃给予菟丝子的95%乙醇提取部位、大孔树脂40%乙醇洗脱部位、正丁醇萃取部位作为给药部位,采用UPLC/Q-TOF-MS技术建立不同给药部位、不同给药次数的血清指纹图谱。同时检测血清中雌二醇(E2)、促卵泡激素(FSH)、促黄体生成素(LH)水平,并进行双变量相关分析和灰关联度分析,筛选雌激素效应组分。结果表明,含药血清中发现9个与雌激素效应高度相关的体内直接作用物质,分别是:金丝桃苷、紫云英苷、甲基化槲皮素葡萄糖醛酸苷、槲皮素-二葡萄糖醛酸苷、槲皮素、芹菜素、异槲皮苷、山柰酚葡萄糖醛酸苷和山柰酚。基于血清谱效相关性的研究思路可初步发现菟丝子拟雌激素作用的体内直接作用物质。为菟丝子雌激素作用药效物质的揭示和质量标志物的确证提供了初步参考。本实验获得了哈尔滨商业大学伦理委员会的批准(批准号:HSDU2020-065)。
