薄层色谱法是一种吸附薄层色谱分离法,它利用各成分对同一吸附剂吸附能力不同,使在流动相(溶剂)流过固定相(吸附剂)的过程中,连续的产生吸附、解吸附、再吸附、再解吸附,从而达到各成分的互相分离的目的。薄层色谱法应用广泛,可用于化合物的鉴别和少量化合物的分离、用于检测药品含量、药物合成中用于鉴别反应程度和监控反应历程、用于摸索高效液相的色谱条件等。


bocengsepufazaizhongyaofenxifangmiandefazhanlicheng:

薄层色谱法鉴别是在1985版中国药典被首次收载的,但由于受到当时可获得的化学对照品的缺乏故仅限于个别的专论中。实践表明化学对照品的缺乏阻碍了薄层色谱法鉴别在草药中应用的拓展。甚至一些多数草药共同含有的化学对照品对于质量评价来说是不太重要的。为了解决薄层色谱法鉴别中的瓶颈问题,对照药材自1990版中国药典起被引入了薄层色谱法鉴别项当中。众所周知,薄层色谱法的独一无二的优势是能够提供类似图画的成像使得草药中的成分组成能够整体地被可视化。不同种属的草药产生的薄层色谱法图像具有各自的专属性。

薄层色谱法在复杂体系药物的检测方面应用越来越广,且05版药典在薄层鉴别收载方面呈现如下特点:
    在已有的薄层鉴别中,2015版药典增加了专属性更强的药材作对照。与对照品相比,本版药典更强调使用对照药材做鉴别,以增加整体专属性,新增的513个薄层色谱法鉴别中,使用对照药材的占61.6%;
    增加对照品同时作对照,使鉴别更具针对性和专属性。对照品和对照药材同时使用,增强专属性,空白不得有干扰;
    将有较好专属性的成分替换专属性不佳的成分。
    薄层色谱法有操作方便、设备简单、显色容易、速度快等特点,在我国中药发展历程中至关重要,已为中药生产及质量监督管理部门所广泛认同。随着薄层色谱技术的不断发展,它在中药标准研究方面有更广阔的前景。
