气相色谱-质谱联用测定止痛药中有效成分的质量
当人体生理系统的某些部分出了问题时,疼痛能起到警示作用。疼痛的刺激从来都不容易定义,也不容易消除,因此有必要将疼痛作为症状来对待。因此,许多制药公司已经冒险进入生产非处方药物(OTC)的业务,这导致了止痛药的生产,以不同的品牌名称到达消费者。本研究旨在确定目前在肯尼亚销售的各种止痛药物中对乙酰氨基酚(4 ' -羟基乙酰苯胺)、阿司匹林(乙酰水杨酸)和咖啡因(3,7-二氢-1,3,7-三甲基-1- h -嘌呤- 2,6 -二酮)活性成分的质量。九种止痛药(panadol, action, hedex, maramoja)。P500, P5500, elymol, neldol和APC片)随机从肯尼亚内罗毕附近的多家商店购买,并带到乔莫·肯雅塔农业技术大学(JKUAT)实验室进行分析。使用二氯甲烷(DCM)进行提取,并通过气相色谱-质谱(GC-MS)分析提取物的活性成分质量。气相色谱-质谱分析采用8串联气相色谱系统,采用Trio-01质谱检测器,电子电离(EI)模式。采用毛细管柱TFX-5 (30mX0.25mm id, 0.25 μ m薄膜)进行分离。结果表明,panadol中的对乙酰氨基酚水平与Neladol和Elymol (455-560mg/片)相当,而hedex的含量最低(24mg/片)。 These values agreed well with the value on the label on the blistered pack. The highest amount of asprin was found in maramoja (937mg/tablet) followed by hedex (790mg/tablet). Panadol, Elymol and Neladol asprin contents were below detectable limits. Maramoja (93mg/tablet) had high amounts of caffeine which was not significant to that of Action 50mg/tablet). Panadol (0.1mg/tablet) had the lowest caffeine content. The outcome of this study suggests the possible availability of counterfeit drugs in the market. The brand mostly affected for analysis of acetaminophen was found in panadol, action, P500, P5500, elymol and neladol.
