同时估计薄荷、樟脑和水杨酸甲酯抗风湿喷雾使用气相色谱法

一个简单、快速、准确、精确和可靠的气相色谱(GC)方法已经开发了薄荷醇的同时估计,樟脑和水杨酸甲酯的抗风湿喷雾。这三个组分的分离进行DB-23列(60 m×250µm×0.25µm)。氮气作为载气的流量2.5 mL / min。入口温度和检测器温度设置为250°C和280°C。最初的烤箱温度为125°C 5分钟,然后增加到150°C的坡道3°C /分钟,最后达到200°C的坡道10°C /分钟。肌萎缩性侧索硬化症(自动液体取样器)系统是用于注射试样。注射2µl成交。色谱图的运行时间为20.333分钟。拟议中的GC方法提供了一个很好的解决薄荷醇,樟脑和水杨酸甲酯。该方法根据我的指导方针进行验证。薄荷醇的线性,樟脑和水杨酸甲酯被发现在10 - 50µg /毫升,20µg /毫升和100 - 300年分别µg /毫升。 The recovery was calculated by using external standard method and the mean average recovery for Menthol, Camphor and Methyl Salicylate were found to be 100.55%, 99.93% and 99.95%. The tested validation parameters were found to be within acceptable limits. The method was successfully applied for quantification of these three ingredients in anti-arthritic spray formulation.
