Description
本发明涉及化学检测领域,特别涉及一种醒脑静注射液中大分子物质的检测方法。
醒脑静注射液是由麝香、冰片、郁金和栀子经水蒸气蒸馏提取精制而成的复方中药注射液,始创于上世纪70年代,组方由中医名方安宫牛黄丸化裁而得,具有清热解毒,凉血活血,开窍醒脑功效。
中药注射剂残留的微量大分子物质如蛋白质、缩合鞣质等可能是导致中药注射剂安全性的重要原因。国家食品药品监督管理局出台了“中药注射液安全性在评价质量控制点”,明确要求对于具体品种的工艺条件下可能存在、而在质量研究中未检出的大类成分,应建立排除性检查方法,必要时应建立高分子量物质检查项。本研究正是基于这一要求展开,建立了一种简便快捷的方法检测醒脑静注射液中的大分子物质。
现有注射剂对大分子物质的检测,已有报道,如:中国专利“一种舒血宁注射液中大分子物质的检测方法”;“一种冠心宁注射液中大分子物质的检测方法”“一种红花注射液中大分子物质的检测方法”“中药注射剂中大分子物质筛查方法研究”等,但目前没有关于醒脑静注射液中大分子物质的检测方法,为了建立准确、灵敏、实用的大分子物质检测方法,对有效控制醒脑静注射剂中大分子物质,提高中药注射剂的用药安全性,本发明在现有技术的基础上进行了大的改进,研究出一种适合本发明的方法。
发明内容
一种醒脑静注射液中大分子物质的检测方法,所述方法,步骤如下:
步骤1:对照品储备液的配制
生长抑素储备液(0.4mg/ml):取约2mg,精密称定,置5ml容量瓶中,加流动相稀释即可。
胸腺肽α1储备液(0.4mg/ml):取约2mg,精密称定,置5ml容量瓶中,加流 动相稀释即可。
人胰岛素储备液(0.4mg/ml):取约2mg,精密称定,置5ml容量瓶中,加流动相稀释即可。
核糖核酸酶A储备液(0.4mg/ml):取约2mg,精密称定,置5ml容量瓶中,加流动相稀释即可。
步骤2:混合对照品溶液的配制
精密量取步骤1各对照品储备液1ml,置5ml容量瓶中,加流动相稀释至刻度,即得每1ml中分别约含生长抑素0.08mg、胸腺肽α1 0.08mg、人胰岛素0.08mg、核糖核酸酶A 0.08mg的混合对照品溶液。
步骤3:供试品溶液的配制
取脑静注射液,用水稀释,或者不经过稀释,直接作为供试品溶液。
步骤4:取混合对照品溶液和供试品溶液,注入高效液相色谱仪,得到色谱图,根据色谱图,计算供试品溶液中生长抑素、胸腺肽α1、人胰岛素、核糖核酸酶A的含量,也可以根据色谱峰,计算其他成份的含量。
